Description

  The present invention relates to a mail list display program and a list display program for scrolling and displaying a list of mails stored in a mailbox of a server connected via a network in a window of a display unit.

  Conventionally, there is web mail software (hereinafter referred to as web mail) for browsing electronic mail on browser software instead of mailer software. In such a web mail, for all mails stored in the mailbox, only the subject is received first and displayed in a list on the terminal side, and only the text of the mail instructed by the user from the list is displayed again. The method of downloading from a mailbox is taken.

  In such a web mail, when there are a large number of received mails and the titles of all cases cannot be displayed on one screen, a list of one screen (for example, 10) is displayed. And if the instruction | indication which displays the list for the next 10 cases is received, the list for the next 10 cases will be received and displayed from a mailbox (for example, patent documents 1).

  Further, Ajax (Asynchronous JavaScript (registered trademark) + XML, asynchronous communication technology) exists as a technique for updating data to be displayed without causing reloading. In such web mail using Ajax, the subject of the list display is received from the mailbox for all mails existing on the mail server regardless of unread and read, and a list is created and displayed based on the information. The mail body is acquired and stored asynchronously before the mail body request is accepted.

  Embodiments of a mail list display program and a list display program according to the present invention will be described below in detail with reference to the accompanying drawings.

  In the following embodiments, the outline and features of the web mail system according to the first embodiment, the configuration of the web mail system, and the flow of processing will be described in order, and finally the effects of the first embodiment will be described.

[Outline and Features of Web Mail System According to Embodiment 1]
First, the outline and features of the web mail system 1 according to the first embodiment will be described with reference to FIGS. 1 to 3 are diagrams for explaining the outline and features of the web mail system according to the first embodiment.

  As shown in FIG. 1, a web mail system 1 according to the first embodiment includes a web server 10 that manages mail and provides a mail-related service, and a user terminal 20 that can access at least the web server 10 (for example, a personal computer). Or a workstation, a home game machine, an Internet TV, a PDA, or a mobile communication terminal such as a mobile phone or a PHS) via a network (for example, the Internet or a local area network). Composed. The web server 10 is connected to a mail server 30 having a user's mailbox so as to be communicable via a network.

  Outline of the web mail system 1 according to the first embodiment having such a system configuration is that a list of mails stored in a mailbox is scrolled and displayed in a list window of a display unit in the user terminal 20. As described below, there are main features in improving operability and ensuring security.

  In the web mail system 1 according to the first embodiment, the web server 10 accesses the mail server 30 in response to a request from the user terminal 20 (or periodically regardless of a request from the user terminal 20). The mail stored in each mailbox is received, and the mail ID database 14a, the list information database 14b, and the mail text information database 14c shown in FIG. 1 are created.

  Here, the mail ID database 14a is a mail for uniquely identifying each mail for all the mails stored in each user's mailbox in association with a user ID uniquely assigned to each user. This is a database that stores IDs and the number of such items (the total number of emails). The list information database 14b is a database that stores list information (for example, information such as a subject name and a sender name) used when displaying each mail in a list on the user terminal 20 in association with the mail ID. is there. Further, the mail text information database 14c is a database that stores mail text information used when displaying the text of each mail on the user terminal 10 in association with the mail ID.

  Then, after accessing the web server 10, the user terminal 20 transmits the user ID to the web server 10 when the user's mailbox is selected by the user (see (1) in FIG. 1). Then, the web server 10 is requested for the mail ID and the number of the mails stored in the mailbox (see (2) in FIG. 1). For example, the user terminal 20 transmits information such as a user ID “1” to the web server 10.

  On the other hand, the web server 10 reads each mail ID and number corresponding to the user ID from the mail ID database 14 a in response to a request from the user terminal 20, and transmits each mail ID and number to the user terminal 20. Then, the user terminal 20 stores each mail ID and the number of cases received from the web server 10 in the mail ID storage unit 25a (see (3) in FIG. 1). As a specific example, the web server 10 transmits information “mail ID“ 1 ”to“ 200 ”, 200” ”corresponding to the user ID“ 1 ”to the user terminal 20, and the user terminal 20 Stores the information “mail ID“ 1 ”to“ 200 ”, 200” ”in the mail ID storage unit 25a.

  Then, according to the scroll position of the list window for all mails, the user terminal 20 transmits the mail ID of the mail corresponding to the scroll position to the web server 10 and uses it for list display of the mail. When the list is displayed for the first time from a state where the list is not yet displayed, it is assumed that the scroll pointer in the scroll bar in the list window is at the top position, and the predetermined mail ID is The data is transmitted to the server 10 (see (4) in FIG. 1). To give a specific example, the user terminal 20 divides the number of display items to be displayed in the list window (for example, 10 items) by a predetermined number of items (for example, 10 items) located in the forward and backward directions of the display object. The setting number (for example, 60 cases before and after 25) is added by setting, and each mail ID (for example, mail ID “ 1 ”to“ 60 ”) is transmitted to the web server 10 to request mail list information corresponding to the transmitted mail ID.

  On the other hand, when the web server 10 receives the mail ID together with the request for list information from the user terminal 20, the web server 10 reads the list information corresponding to the received mail ID from the list information database and transmits it to the user terminal 20 ( The user terminal 20 stores each mail ID and list information received from the web server 10 in association with the list information storage unit 25b (see (6) in FIG. 1). . Specifically, in the above example, the web server 10 reads the list information for each mail corresponding to the mail IDs “1” to “60” from the list information database and transmits it to the user terminal 20. The user terminal 20 stores the list information for the mail IDs “1” to “60” in the list information storage unit 25b.

  Subsequently, the user terminal 20 generates a list to be displayed in the list window based on the list information stored in the list information storage unit 25b and outputs the list to the list window ((( 7) and (8)). Specifically, in the above example, the user terminal 20 assumes that the scroll pointer in the scroll bar in the list window is at the top position, and sets the number of messages from the top position for all mails. Since the list information (for example, the list information for each of the mail IDs “1” to “60”) is acquired for each mail, the list information for each mail corresponding to the number of displayed messages from the top position for all mails. A list to be displayed in the list window is generated using the mail IDs “1” to “10” (for example, information for each list), and this list is output to the list window. Note that the user terminal 20 sets the position of the scroll pointer on the scroll bar to the display target position (here, the top position) for all mails, and sets the size of the scroll pointer to all mails when displaying the list. The ratio of the number of display items to the number (here, 10/200) is set, and the scroll bar set in this way is displayed and output together in the list window.

  Next, description will be made with reference to FIG. When the user terminal 20 receives an instruction to move the scroll through the scroll bar (see (1) in FIG. 2), the user terminal 20 generates a list to be displayed in the list window according to the position of the scroll pointer on the scroll bar. To the list window (see (2) to (4) in FIG. 2). More specifically, in the above example, the user terminal 20 uses the list information (e.g., mail IDs “1” to “60”) for each mail corresponding to the set number of mails from the top position for all mails. In the state where each list information) is acquired, when a scroll movement instruction is received such that the position of the scroll pointer is “11 to 20” from the top position for all mails, In the list window, the information for the list of each mail located at “11 to 20” from the top position for all mails (for example, the list information for each of the mail IDs “11” to “20”) is used. Generate a list that should be displayed and output this list to the list window. Note that the user terminal 20 sets the position of the scroll pointer on the scroll bar to the display target position for all mails (here, “11 to 20 items” from the top position) when displaying the list. .

  Then, as described above, the user terminal 20 generates a list to be displayed in the list window according to the position of the scroll pointer and outputs it to the list window. The position of the scroll pointer for the list information stored in the information storage unit is monitored. Specifically, the list information stored in the list information storage unit is the information for the list of mails that are located in the scrolling direction when viewed from all the mails, and has not yet been displayed in the window. It is monitored whether or not the number of list information items has become a predetermined threshold value (for example, 10 items) or less (see (5) in FIG. 2). For example, as described above, for example, as described above, list information for each of a set number of mails from the top position with respect to all mails (for example, mail IDs “1” to “60” respectively) In this state, it is monitored whether or not a scroll movement instruction is received so that the position of the scroll pointer is positioned at “50th” from the top position for all mails.

  When it is determined by monitoring the scroll pointer that the number of list information items that are not yet displayed in the window has become equal to or smaller than a predetermined threshold, the user terminal 20 determines whether the user terminal 20 has a predetermined number of items that are continuous in the scrolling direction. The mail ID is transmitted to the web server 10 and a new list information is requested (see (6) in FIG. 2). Specifically, in the above example, when a scroll movement instruction is received such that the position of the scroll pointer is “50th” from the top position for all mails, a predetermined number of cases following the mail ID “60” are received. Each mail ID (for example, mail IDs “61” to “120”) is transmitted to the web server 10 as a minute mail, and the mail list information corresponding to the transmitted mail ID is requested.

  On the other hand, when the web server 10 receives a mail ID from the user terminal 20 together with a request for list information, the web server 10 reads the list information corresponding to the received mail ID from the list information database and uses it. The user terminal 20 stores each mail ID and list information received from the web server 10 in association with the list information storage unit 25b (see FIG. 2 (7)). 2 (8)). Specifically, in the above example, the web server 10 reads out the list information for each mail corresponding to the mail IDs “61” to “120” from the list information database and transmits it to the user terminal 20. The user terminal 20 stores the list information for the mail IDs “61” to “120” in the list information storage unit 25b. As a result, the user terminal 20 has acquired the list information for the mail IDs “1” to “120”, and uses the list information as described above, according to the position of the scroll pointer. A list to be displayed in the list window is generated and output to the list window (see (1) to (4) in FIG. 2).

  Next, description will be made with reference to FIG. As described above, the user terminal 20 also performs a process of monitoring the position of the scroll pointer and requesting information for the list in parallel with the process of generating a list according to the position of the scroll pointer and outputting the list to the list window. However, when monitoring the position of the scroll pointer, not only monitoring whether or not the number of list information items not yet displayed in the window has become a predetermined threshold value (for example, 10 items) or less. Further, it is also monitored whether or not the list information of the mail to be displayed in the window is not stored in the list information storage unit 25b in accordance with an instruction to move the scroll greatly ((1) in FIG. 3). And (2)). For example, as described above, for example, as described above, list information for each of a set number of mails from the top position with respect to all mails (for example, mail IDs “1” to “60” respectively) In this state, it is monitored whether or not a scroll movement instruction is received so that the position of the scroll pointer is positioned after the “60th” from the top position for all mails.

  When it is determined by monitoring of the scroll pointer that the list information of the mail that is actually displayed in the window is not stored in the list information storage unit 25b, the user terminal 20 displays the list. The set number of items (for example, 10 items) added to the number of displayed items to be newly displayed in the window (for example, 10 items), plus a predetermined number of items (for example, 25 items before and after) in the forward and backward directions of the display object. , 60 mails), each mail ID is transmitted to the web server 10 to request mail list information (see (3) in FIG. 3). Specifically, from the state in which the list of each of the mail IDs “1” to “10” is output to the list window, the position of the scroll pointer is “145 from the top position for all mails. Upon receiving the scroll movement instruction located at “˜155 cases”, the user terminal 20 sends the mail IDs “121” to “180” to the web server 10 and lists the mails corresponding to the sent mail IDs. Request information for use.

  On the other hand, when the web server 10 receives a mail ID together with a request for list information from the user terminal 20 as in the description of FIGS. 1 and 2, the list information corresponding to the received mail ID is retrieved from the list information database. The information is read and transmitted to the user terminal 20 (see (4) in FIG. 3), and the user terminal 20 stores each mail ID and list information received from the web server 10 in association with the list information storage unit 25b. (See (5) in FIG. 3). Specifically, in the above example, the web server 10 reads the list information for each mail corresponding to the mail IDs “121” to “180” from the list information database and transmits it to the user terminal 20. The user terminal 20 stores the list information for the mail IDs “121” to “180” in the list information storage unit 25b.

  Subsequently, the user terminal 20 generates a list to be displayed in the list window based on the list information stored in the list information storage unit 25b and outputs the list to the list window ((( 6) to (8)). Specifically, in the above example, the user terminal 20 accepts a scroll movement instruction in which the position of the scroll pointer is “145 to 155” from the top position for all mails. Since the list information has been requested, the list information for each mail (for example, each of the mail IDs “145” to “155”) located at “145 to 155” from the top position for all mails. ) Is used to generate a list that should be displayed in the list window, and this list is output to the list window.

  As described above, the web mail system 1 also manages all messages on the server side, and lists information used for list display only for mails that need to be listed in the window from all the mails. As a result of reducing the waiting time due to communication and allowing all titles to be browsed continuously according to the scroll position of the window, as described above, the operability is improved and security is ensured. Is possible.

  Among these, the mail ID request unit 24 a is a processing unit that requests the web server 10 for a mail ID for uniquely identifying each mail and receives the mail ID from the server 10. Specifically, when the user's mailbox is selected by the user, the mail ID requesting unit 24a transmits the user ID to the web server 10 so that all the mails stored in the mailbox are received. Are requested to the web server 10, and each mail ID and number received from the web server 10 are stored in the mail ID storage unit 25a.

  The list information request unit 24b is a processing unit that requests the list information from the web server. Specifically, according to the scroll position of the list window for all mails, the mail ID of the mail corresponding to the scroll position is transmitted to the web server 10 to request the list information used for displaying the mail list. .

  Here, the list information request processing will be described in detail with reference to FIGS. FIG. 13 is a diagram for explaining the processing of the list information request unit 24b when a list is first displayed upon receiving a mailbox selection instruction. FIG. 14 shows the list information request unit 24b when the scroll is moved. FIG. 15 is a diagram for explaining the processing of the list information request unit 24b when the scroll is largely moved.

  As shown in FIG. 13, when the list information request unit 24b first displays a list from a state in which the list is not yet displayed, the scroll pointer in the scroll bar in the list window is at the head position. Assume that a predetermined mail ID (for example, mail IDs “1” to “60”) is transmitted to the web server 10. To give a specific example, the list information requesting unit 24b adds the number of display items to be displayed in the list window (for example, 10 items) to the number of predetermined items positioned in the forward and backward directions of the display target ( For example, the number of setting items (for example, 25 items before and after) is retained by setting, and each mail ID (for example, e-mail) is set for all the e-mails for the set number of e-mails from the top position. IDs “1” to “60”) are transmitted to the web server 10 to request and receive mail list information corresponding to the transmitted mail ID. Then, the list information storage unit 24c described later stores the received list information (for example, the mail IDs “1” to “60”) in the list information storage unit 25b.

  Further, as shown in FIG. 14, the list information request unit 24b includes the list information of the mail positioned in the scrolling direction in view of all the mails in the list information stored in the list information storage unit. Then, it is monitored whether or not the number of list information items not yet displayed in the window is equal to or less than a predetermined threshold (for example, 10 items). Explaining in more detail by example, the list information requesting unit 24b, for example, lists information (e.g., mail IDs “1” to “1”) for each mail corresponding to the set number of mails from the head position for all mails. In the state where the “60” information for each list) is acquired, it is monitored whether or not a scroll movement instruction has been accepted so that the position of the scroll pointer is located at “50th” from the top position for all mails. To do.

  If it is determined by monitoring the scroll pointer that the number of list information items not yet displayed in the window has become equal to or less than a predetermined threshold value, the list information request unit 24b determines the predetermined number of items in the scrolling direction. A mail ID is transmitted to the web server 10 for the number of mails, and a new list information is requested. In the example of FIG. 14, when the list information requesting unit 24b receives a scroll movement instruction in which the position of the scroll pointer is “50th” from the top position for all mails, the mail ID “ Each mail ID (for example, mail IDs “61” to “120”) is transmitted to the web server 10 as a predetermined number of mails following “60”, and a request for mail list information corresponding to the transmitted mail ID is requested. And receive. Then, the list information storage unit 24c described later stores the received list information (for example, the mail IDs “61” to “120”) in the list information storage unit 25b.

  Further, as shown in FIG. 15, the list information request unit 24b monitors the position of the scroll pointer in parallel with the process of generating the list according to the position of the scroll pointer and outputting it to the list window. Although processing for requesting information is also performed, when monitoring the position of the scroll pointer, whether or not the number of items of list information not yet displayed in the window is equal to or less than a predetermined threshold (for example, 10). It is also monitored whether or not the list information of the mail to be displayed in the window is not stored in the list information storage unit 25b in accordance with an instruction to move the scroll greatly. (See (1) and (2) in FIG. 3). Explaining in more detail with an example, for example, as described above, the list information request unit 24b lists information for each mail corresponding to the set number of mails from the head position for all mails (for example, mail ID). In the state where “1” to “60” information for each list) is acquired, a scroll movement instruction is made so that the position of the scroll pointer is located after “60th” from the top position for all mails. Monitor whether it was accepted.

  When it is determined by monitoring of the scroll pointer that the list information of the mail that is actually displayed in the window is not stored in the list information storage unit 25b, the list information request unit 24b , The number of settings that is added to the number of items to be newly displayed in the list window (for example, 10 items) plus the predetermined number of items to be displayed in the forward and backward directions (for example, 25 items before and after). For (for example, 60) mails, each mail ID is transmitted to the web server 10 to request mail list information (see (3) in FIG. 3). Specifically, the list information request unit 24b starts from the state where each list of the mail IDs “1” to “10” is output to the list window, and the position of the scroll pointer is set to all mails. On the other hand, when a scroll movement instruction such as “145 cases to 155 cases” is received from the head position, the user terminal 10 transmits the mail IDs “121” to “180” to the web server 10 and transmits them. Request and receive mail list information corresponding to the mail ID. Then, the list information storage unit 24c described later stores the received list information (for example, the list information of the mail IDs “121” to “180”) in the list information storage unit 25b.

  The list information storage unit 24c is a processing unit that stores the list information in the list information storage unit 25b. Specifically, each mail ID and list information received from the web server 10 are stored in association with the list information storage unit 25b.

  The list generation unit 24d is a processing unit that generates a list to be displayed in the list window based on the list information stored in the list information storage unit 25b. Specifically, the list generation unit 24d assumes that the scroll pointer in the scroll bar in the list window is at the top position, and uses the list for each mail for the number of displayed messages from the top position for all mails. A list to be displayed in the list window is generated using information (for example, information for each of the mail IDs “1” to “10”).

  In addition, the list generation unit 24d acquires list information (for example, list information for each of the mail IDs “1” to “60”) for each set number of mails from the top position for all mails. When the scroll movement instruction is received such that the position of the scroll pointer is “11 to 20” from the top position for all mails, A list to be displayed in the list window is generated using the list information for each mail located at “11 to 20” (for example, the list information for each of the mail IDs “11” to “20”).

  In addition, when it is determined that the list information of the mail that is currently displayed in the window is not stored in the list information storage unit 25b, the list generation unit 24d displays the list information storage unit 25b. The list to be displayed in the list window is generated based on the list information stored in the list window.

  The list output unit 24e is a processing unit that outputs a list. Specifically, the list output unit displays the list generated by the list generation unit 24d on the output unit 22, as illustrated in FIG.

  The mail text information request unit 24f is a processing unit that requests the web server 10 for mail text information. Specifically, the mail body information request unit 24f transmits the mail ID of the mail to the server for the mail received from the input unit 21 as an instruction to view the mail body, and sends the mail body information of the mail. Request and receive.

  The mail text output unit 24 g is a processing unit that outputs the mail text to the output unit 22. Specifically, the mail text output unit 24g uses the mail text information received by the mail text information requesting unit 24f as shown in FIG. 17 for the mail text provided separately from the window in which the list is displayed. Output to window.

[Processing by web mail system]
Next, processing by the web mail system 1 according to the first embodiment when the user's mailbox is selected will be described with reference to FIG. FIG. 18 is a flowchart illustrating the processing operation of the web mail system 1 according to the first embodiment.

  As shown in the figure, when receiving a mailbox selection instruction (Yes at Step S101), the user terminal 20 receives a user ID (for example, a user ID “1”) that is uniquely assigned to the user by the web server 10. ]) Is transmitted to the web server 10 (step S102). When receiving the request from the user terminal 20, the web server 10 transmits the mail ID stored in the list information database 14b and the number of cases to the user terminal 20 as illustrated in FIG. 8 (step S103). . Note that the user terminal 20 stores each mail ID and number received from the web server 10 in the mail ID storage unit 25a.

  Then, the user terminal 20 acquires the mail ID and the number of mails (for example, mail IDs “1” to “200”, 200) corresponding to the user ID from the web server 10, and displays the window of all the mails. In accordance with the scroll position (the position of the pointer in the scroll bar), the mail ID of the mail corresponding to the scroll position is transmitted to the web server 10 to request the list information used for displaying the mail list (step S104). . Then, the web server 10 transmits the requested list information to the user terminal 20 (step S105).

  Subsequently, the user terminal 20 stores the received list information in a predetermined list information storage unit 25b (step S106), and outputs an output unit based on the list information stored in the list information storage unit 25b. A list (for example, a list of 10 items) that should be displayed in 22 is generated and output to the output unit 22 (step S107), and the list of 10 items is displayed (step S108).

[Processing by web mail system when scroll is moved]
Next, processing by the web mail system 1 according to the first embodiment when the scroll is moved will be described with reference to FIG. FIG. 19 is a flowchart showing the processing operation of the web mail system 1 when the scroll is moved.

  As shown in the figure, when the user terminal 20 receives a scroll movement instruction through the scroll bar (step S201), the user terminal 20 moves to the list information storage unit 25b according to the scroll movement (at the position of the pointer in the scroll bar). Accordingly, if there is list information for a list that should be displayed in the output unit 22 (Yes in step S202), a list is created based on the list information stored in the list information storage unit 25b ( In step S203), according to the movement of the scroll (according to the position of the pointer in the scroll bar), a list (for example, a list of ten items) that should be displayed in the output unit 22 is output to the output unit 22. (Step S204).

  When the user terminal 20 receives a scroll movement instruction through the scroll bar (step S205), the user terminal 20 determines whether it is necessary to request the list information (step S206). In other words, in parallel with the process of generating a list according to the position of the scroll pointer and outputting it to the list window, the process of monitoring the position of the scroll pointer and requesting the list information is also performed. When monitoring, not only whether the number of items of list information not yet displayed in the window has become a predetermined threshold (for example, 10) or less, but also by an instruction to move the scroll greatly It is also monitored whether or not the list information of the mail that is actually displayed in the window is not stored in the list information storage unit 25b. As a result, the user terminal 20 does not need to request the list information (the number of the list information items that are not yet displayed is greater than or equal to a predetermined threshold value, or for the list of mails that are actually displayed in the window. In a state in which the information is stored in the list information storage unit 25b), the process ends without requesting the list information from the web server 10 (No in step S206).

  As a result, when the user terminal 20 determines that the number of items of list information not yet displayed in the window has become equal to or less than a predetermined threshold by monitoring the scroll pointer (Yes in step S206). Then, a mail ID is transmitted to the web server 10 for a predetermined number of mails that are continuous in the scrolling direction, and a new list information is requested (step S207). Then, the web server 10 transmits the list information corresponding to the received mail ID to the user terminal 20 (step S208). Then, the user terminal 20 stores the received list information in the list information storage unit 25b (step S209). If step S202 is NO, data necessary for list display in the list information storage unit 25b is obtained by the process starting from step S205 performed in parallel with the process starting from step S201 while the determination of step S202 is repeated. Is stored, the determination in step S202 becomes YES at the stored stage.

  As a result of the above, if it is determined by monitoring the scroll pointer that the list information for the mail that is currently displayed in the window is not stored in the list information storage unit 25b (step S206). (Yes), the user terminal 20 divides the number of display items to be newly displayed in the list window (for example, 10 items) by a predetermined number (for example, 25 items before and after the display object). For each of a set number of mails (for example, 60 mails) added, each mail ID is transmitted to the web server 10 to request mail list information (step S207). Then, the web server 10 transmits the list information corresponding to the received mail ID to the user terminal 10 (step S208). Then, the user terminal 10 stores the received list information in the list information storage unit 25b (step S209).

[Mail text output processing by web mail system]
Next, mail text output processing by the web mail system 1 according to the first embodiment will be described with reference to FIG. FIG. 20 is a flowchart showing the mail text output processing operation by the web mail system 1.

  As shown in the figure, when the user terminal 20 receives an instruction to browse the mail text from the input unit 21 (Yes in step S301), the mail text information of the mail that has received the instruction to browse is mail. It is determined whether the text information storage unit 25c is present (step S302). As a result, when the mail text information is stored in the mail text information storage unit 25c (Yes in step S302), the user terminal 20 outputs the mail text to the output unit 22 based on the mail text information. (Step S305).

  On the other hand, when the mail text information is not in the mail text information storage unit 25c (No at Step S302), the user terminal 20 transmits the mail ID of the mail that has received an instruction to browse to the web server 10. (Step S303). Then, the web server 10 transmits mail body information corresponding to the received mail ID to the user terminal 20 (step S304). Thereafter, the mail text is output to the output unit 22 based on the mail text information (step S305).

[Effect of Example 1]
As described above, the web mail system 1 receives the mail ID for uniquely identifying each mail from the web server 10 for all the mails stored in the mailbox, and the window for all the mails is displayed. In response to the scroll position, the mail ID of the mail corresponding to the scroll position is transmitted to the web server 10 to request the list information used for the list display of the mail, and the mail corresponding to the requested mail ID is listed. Receiving information from the web server 10, storing the received list information in a predetermined list information storage unit 25b, and generating a list to be displayed in the window based on the stored list information Will be output to that window, so you can select all of the emails that need to be listed in the window. As a result of receiving the list information used for displaying the list and reducing the waiting time due to communication and allowing all titles to be browsed continuously according to the scroll position of the window, it is as if all cases It is possible to improve the operability by displaying the terminal as if it has been received. In addition, since all messages are managed on the web server 10 side, security can be ensured.

  Further, according to the first embodiment, when the list information of the mail that is actually displayed in the window is not stored in the list information storage unit 25b, the display is performed in addition to the mail that is the display target. The mail ID is also sent to the server for a predetermined number of mails that are located in the forward and / or backward direction of the target, so when displaying the list first or when the scroll bar is moved greatly, a new list is displayed. When displaying, not only the mail currently displayed in the window, but also extra information for a predetermined number of mails located before and after the scroll bar is obtained, and in response to a slight scrolling operation thereafter As a result of promptly generating a list based on previously obtained list information without newly requesting list information, the operability can be further improved. It is a function.

  Further, according to the first embodiment, the list information stored in the list information storage 25b is the mail list information positioned in the scrolling direction as viewed from all the mails, and is still displayed in the window. If the number of unlisted information falls below a predetermined threshold, mail IDs are sent to the server for a predetermined number of mails that continue in the scrolling direction. The list information is acquired in advance, and the list is quickly generated based on the list information acquired in advance without requesting the list information in response to the subsequent scrolling operation. As a result, the operability can be further improved.

  Further, according to the first embodiment, for a mail that has received an instruction to view the mail text from the input unit, the mail ID of the mail is transmitted to the server to request information for the mail text of the mail. Received mail body information from the server, and outputs the received mail body information to a mail body window provided separately from the window, so it receives the mail body information using the mail ID and displays a list It is possible to output the mail text in a mail text window provided separately from the window to be executed.

  Further, according to the first embodiment, for all cases of mail stored in the mailbox for each user, a mail ID for uniquely identifying each mail is stored in the predetermined mail ID database 14a, and the mail ID database Corresponding to the mail ID stored in 14a, the list information used when displaying each mail as a list on the user terminal 20 is stored in the predetermined list information database 14b, and in response to a request from the user terminal 20 Then, the mail ID stored in the mail ID database 14a is transmitted to the user terminal 20 for all the mails stored in the user's mailbox corresponding to the user terminal 20, and the user terminal 20 When a mail ID of a predetermined mail is received together with a request for list information, the list information corresponding to the received mail ID Since the information is read from the list information database 14b and transmitted to the user terminal, the list information used for the list display is received and communicated only for the mail that needs to be displayed as a list in the window from all the mails. As a result of reducing the waiting time due to and allowing all titles to be browsed continuously according to the scroll position of the window, it is possible to improve the operability by displaying as if all cases were received. It is. In addition, since all messages are managed on the web server 10 side, security can be ensured.
