Detailed Description

Reference will now be made in detail to the embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the like or similar elements throughout. The embodiments described below with reference to the drawings are exemplary and intended to be illustrative of the present disclosure, and should not be construed as limiting the present disclosure.

The disclosed embodiment provides a page window communication method aiming at the problem that in the related art, the existing method for realizing the communication between page windows by calling a window.

The page window communication method provided by the embodiment of the disclosure calls a page opening function by using a second page parameter to be communicated through a first page to obtain a window object of the second page, and registers a page window loading callback function in the window object of the second page, so that when the first page detects that the loading callback function is called, the first page sends a communication registration request to the second page, wherein the communication registration request includes a first check code and the page parameter of the first page, so that when the second page determines that the first check code is legal, the window object of the first page is obtained according to the page parameter of the first page. Therefore, the first page opens the second page and obtains the window object of the second page by calling the page opening function, and sends the communication registration request to the second page, so that the second page obtains the window object of the first page through the communication registration request, and then the first page and the second page can send information to the other side by using the window object of the other side, thereby realizing the two-way communication between the page windows and improving the user experience.

The page window communication method, apparatus, electronic device, storage medium, and computer program provided by the present disclosure are described in detail below with reference to the accompanying drawings.

The following describes the page window communication method provided by the embodiment of the present disclosure in detail, taking two page window sides for communication as examples.

First, a page window side initiating communication is taken as an example to describe the page window communication method provided by the embodiment of the present disclosure in detail.

Fig. 1 is a schematic flowchart of a page window communication method provided in an embodiment of the present disclosure, where the method is applied to a page window for initiating communication.

As shown in fig. 1, the page window communication method includes the following steps:

step 101, the first page calls a page opening function by using a second page parameter to be communicated so as to obtain a window object of the second page.

The second page parameter may include a Uniform Resource Locator (URL), a window name, a window feature, and a boolean value of a document displayed in the window. The page open function refers to a function for opening a new browser window or finding a named window.

It should be noted that, in the embodiment of the present disclosure, the page open function may be a window.open () function, and a syntax rule of the window.open () is window.open (URL, name, feature, place). The parameters URL, name, feature and place are respectively URL, window name, window feature and Boolean value of a document displayed in the page to be opened. The first page may call a page open function, and take a known parameter of the second page to be communicated as a parameter of the page open function, thereby opening the second page, and obtaining a return value of the page open function, that is, a window object of the second page.

Further, after the window object of the second page is obtained, the window object of the second page may be stored, so that the window object of the second page is called when the first page communicates with the second page. That is, in a possible implementation form of the embodiment of the present disclosure, after the step 101, the method may further include:

and caching the window object of the second page into a variable corresponding to the second page.

It should be noted that, for storing the window object of the second page, so as to be called when the first page sends information to the second page, a variable corresponding to the second page may be created and named, and then the obtained window object of the second page is cached in the variable corresponding to the second page. For example, the variable name of the variable corresponding to the second page may be set to child window.

And 102, the first page registers a page window in the window object of the second page and loads a callback function.

And the page window loads a callback function for indicating whether the second page is loaded completely.

It should be noted that, if the first page sends information to the second page before all elements in the second page are not loaded, an error may occur when the unloaded elements need to be referred to. Therefore, before the first page establishes communication with the second page, the first page needs to confirm that all elements in the second page are loaded completely, so as to avoid failure in establishing communication connection.

In this embodiment of the present disclosure, the page window load callback function may be a window.onload function, which may be executed after all elements in the page are loaded, so that the first page may register the window.onload function, i.e., the page window load callback function, in the window object of the second page, and when the first page detects that the page window load callback function is called, it may be determined that the second page is loaded completely.

Step 103, when detecting that the load callback function is called, the first page sends a communication registration request to the second page, where the communication registration request includes a first check code and a page parameter of the first page, so that when determining that the first check code is legal, the second page obtains the window object of the first page according to the page parameter of the first page.

In this embodiment of the present disclosure, when the first page detects that the load callback function registered in the window object of the second page is called, it may be determined that all elements in the second page have been loaded, that is, the first page may start to establish a communication connection with the second page.

It should be noted that, when establishing a communication connection with the second page, the first page may first send a communication registration request to the second page, where the communication registration request includes the first check code and the page parameter of the first page. The first check code is used for proving the validity of the first page so as to avoid establishing connection between an illegal page and the second page and ensure the network security. The first check code can be a self-preset password character string and is cached in the first page and the second page, when the second page receives the first check code sent by the first page, whether the first check code is consistent with the password character string cached by the second page can be judged, if so, the first check code can be determined to be legal, and communication connection can be established with the first page; if the first check code is inconsistent with the second check code, the first check code can be determined to be illegal, and the communication registration request sent by the first page can be rejected.

Correspondingly, the second page may obtain the window object of the first page according to the page parameter of the first page included in the communication registration request. When the second page determines that the first check code is legal, the second page can establish communication connection with the first page, namely, the window object of the first page can be obtained according to the page parameters of the first page, a variable corresponding to the first page is set, and the window object of the first page is cached in the variable corresponding to the first page, so that the second page can send information to the first page according to the window object of the first page. For example, the variable name of the set variable corresponding to the first page may be fasternow.

Furthermore, after the first page sends a communication registration request to the second page and the verification is successful, the two-way communication between the first page and the second page can be realized. Before the first page and the second page send information to each other, whether a variable corresponding to the other side is contained in the cache needs to be determined firstly, so that a window object of the other side is called, and the information is delivered successfully. That is, in a possible implementation form of the embodiment of the present disclosure, after the step 103, the method may further include:

when the first page calls a delivery information function, judging whether a cache contains a variable corresponding to the second page, wherein a parameter calling the delivery information function is information to be sent;

and if so, sending the information to be sent to the second page according to the window object of the second page cached in the variable corresponding to the second page.

It should be noted that, when the first page sends information to the second page, the information needs to be sent to the second page by calling a variable corresponding to the delivery information function and the second page. However, after the communication connection between the first page and the second page is established, if the first page or the second page is refreshed, the refreshed page loses a variable corresponding to another page, so that the refreshed page cannot successfully send information to another page. Therefore, before the first page sends information to the second page, whether the cache contains a variable corresponding to the second page or not can be judged firstly, if so, the information to be sent can be sent to the second page according to the window object of the second page cached in the variable corresponding to the second page by calling the delivery information function and setting the information to be sent as a parameter of the delivery information function. Accordingly, the second page may also transmit information to the first page in the same way.

For example, the delivery information function may be a postMessage function, and if the cached variable name corresponding to the first page is fasternow and the cached variable name corresponding to the second page is childWindow, the first page may send information to the second page by calling childWindow. Accordingly, information can be sent to the first page at the second page by calling fastmessage.

Further, if it is determined that the cache does not contain a variable corresponding to another page when the first page or the second page sends information to the counterpart, that is, the cache is refreshed after establishing a communication connection with another page, the information to be sent may be cached, so that the information to be sent is sent to another page again after reestablishing a connection with another page. That is, in a possible implementation form of the embodiment of the present disclosure, after the step 103, the method may further include:

and if the cache does not contain the variable corresponding to the second page, storing the information to be sent into a lost information array by taking the identifier of the second page as an index.

It should be noted that, if it is determined that the cache does not contain the variable corresponding to the second page when the first page sends information to the second page, it may be determined that the first page is refreshed after the second page establishes the communication connection, so that reference to the second page is lost, and information cannot be sent to the second page. Therefore, in a possible implementation form of the embodiment of the present disclosure, when the cache does not include the variable corresponding to the second page, the first page may store the information to be sent in the information array by using the identifier of the second page as an index, so that after the connection between the first page and the second page is reestablished, the information to be sent is resent to the second page, and the reliability of information transmission between page windows is improved. The missing information array may be preset in advance. Correspondingly, if the second page sends information to the first page, it is determined that the cache does not contain the variable corresponding to the first page, and the same method can be used to store the information to be sent into the missing information array.

In a possible implementation form of the present disclosure, if one of the pages performs a refresh operation after the first page and the second page establish a communication connection, the serial port object of the unrefreshed page may be obtained again through information sent by the unrefreshed page to the refreshed page, so as to reestablish a communication connection with the unrefreshed page.

The page window communication method provided by the embodiment of the present disclosure is further described below with reference to fig. 2.

Fig. 2 is a schematic flowchart of another page window communication method provided in the embodiment of the present disclosure.

As shown in fig. 2, the page window communication method includes the following steps:

step 201, when detecting that the message receiving callback function of the first page is called, the first page acquires a calling parameter of the message receiving callback function.

The message receiving callback function of the first page is registered when the first page is loaded and is used for receiving information sent to the first page by other pages. For example, the message receive callback function may be a window.

It should be noted that, when the first page receives information sent by another page, the parameter of the delivery information function called when the other page sends information to the first page may be obtained by calling the message receiving callback function, and the parameter calling the obtained delivery information function is used as the calling parameter of the message receiving callback function of the first page.

Step 202, determining whether the calling parameter includes a parameter of the second page, if yes, executing step 203; otherwise step 205 is performed.

Step 203, acquiring the window object of the second page according to the parameter of the second page.

It should be noted that the call parameter of the message receiving callback function of the first page is determined according to the parameter of the delivery information function called by the page sending information to the first page, and the parameter of the delivery information includes information to be sent, the type of the information to be sent, the current state of the call page, and the parameter information of the call page. If the calling parameter includes a parameter of the second page, it may be determined that the message currently sent to the first page is the second page, that is, the parameter of the second page may be obtained by calling the parameter, a window object of the second page may be obtained according to the parameter of the second page, and the window object may be cached in a variable corresponding to the second page, so as to reestablish the communication connection between the first page and the second page.

Furthermore, when the page windows are communicated, the information to be sent and the check code can be sent together, so that the page receiving the information can check the validity of the sent page, and the security of page communication is improved. That is, in a possible implementation form of the embodiment of the present disclosure, before the step 203, the method may further include:

and determining that the first check code in the calling parameter is legal.

It should be noted that the first page may determine the validity of the first check code by determining whether the first check code in the call parameter is consistent with the preset and cached password character string. Specifically, if the first check code in the calling parameter is consistent with the cached password character string, it may be determined that the first check code is legal, that is, the window object of the second page may be obtained, and a communication connection may be established with the second page; if the first check code in the calling parameter is inconsistent with the cached password character string, the first check code can be determined to be illegal, namely the window object of the second page can not be obtained, and the communication connection with the second page is refused to be established.

And step 204, sending the information to be sent in the lost information array by taking the identifier of the second page as an index to the second page according to the window object of the second page.

In this embodiment of the present disclosure, after the first page acquires the window object of the second page, that is, after the communication connection is reestablished with the second page, it may be determined whether the missing information data includes the information to be sent with the second page identifier as the index according to the window object of the second page. If the page window information is contained in the page window information, the information to be sent can be sent to the second page by calling a delivery information function, so that abnormal communication between the page windows caused by the fact that the communication connection between the first page and the second page is disconnected is avoided.

Further, after the information to be sent in the missing information array by the first page is sent to the second page by using the identifier of the second page as an index, the information to be sent by using the identifier of the second page as an index is invalid. Therefore, in a possible implementation form of the embodiment of the present disclosure, after the step 204, the method may further include:

and clearing the information to be sent in the lost information array by taking the identifier of the second page as an index.

It should be noted that, after the first page sends the to-be-sent information indexed by the identifier of the second page in the missing information array to the second page, the to-be-sent information indexed by the identifier of the second page becomes invalid information, and if the sent to-be-sent information is continuously stored in the missing information array, the sent to-be-sent information indexed by the identifier of the second page is repeatedly sent to the second page after the first page is re-connected with the second page next time. Therefore, the information to be sent can be cleared from the missing information array, so as to save the cache space and avoid the influence on the normal communication between the page windows caused by the repeated sending of the information to be sent.

Step 205, obtaining a window object of the third page according to the parameter of the third page in the calling parameters.

It should be noted that, in a possible implementation form of the embodiment of the present disclosure, mutual communication between multiple pages may be implemented, and therefore, when the first page determines that the call parameter of the message reception callback function does not include the parameter of the second page, then the third page that currently sends information to the first page may be another page that has previously established communication connection with the first page, or a new page that requests to establish communication connection with the first page, that is, the first page may also obtain the window object of the third page according to the parameter of the third page included in the call function, and cache the window object in the variable corresponding to the third page to establish communication connection between the first page and the third page.

Further, since the third page may be a page that has previously established a communication connection with the first page, or may be a new page that requests a communication connection with the first page, it may also be determined whether there is information to be transmitted that the first page has not been successfully transmitted to the third page. That is, in a possible implementation form of the embodiment of the present disclosure, after the step 205, the method may further include:

judging whether the lost information array contains information to be sent with the identifier of the third page as an index;

and if so, sending the information to be sent in the lost information array by taking the identifier of the third page as an index to the third page according to the window object of the third page.

It can be understood that, in the embodiment of the present disclosure, whether the missing information array includes the information to be sent with the identifier of the third page as the index may be determined according to the window object of the third page. If the third page is the page which is communicated with the first page before, the third page can be determined, that is, the information to be sent which takes the identifier of the third page as the index in the missing information array can be sent to the third page according to the window object of the third page, and the information to be sent which takes the identifier of the third page as the index in the missing information array is eliminated.

The page window communication method provided by the embodiment of the disclosure acquires a call parameter of a message receiving callback function when the first page detects that the message receiving callback function of the first page is called, acquires a window object of a second page according to the parameter of the second page when the call parameter is judged to contain the parameter of the second page, and then transmits information to be transmitted, which is indexed by an identifier of the second page in a missing information array, to the second page according to the window object of the second page; otherwise, acquiring the window object of the third page according to the parameter of the third page in the calling parameters. Therefore, the first page receives the calling parameter of the callback function through the message, acquires the window object of the page according to the page parameter contained in the calling parameter, reestablishes communication connection with the page disconnected before, and sends the information to be sent in the missing information array to the corresponding page, so that the two-way communication between the page windows is realized, the communication connection between the page windows is reestablished after one page window is refreshed, and the user experience is further improved.

The page window communication method provided by the embodiment of the present disclosure is described in detail below by taking the page window side that receives the communication request as an example.

The page window communication method provided by the embodiment of the present disclosure is further described below with reference to fig. 3.

Fig. 3 is a schematic flowchart of another page window communication method provided in the embodiment of the present disclosure, which is applied to a page window of a communication request.

As shown in fig. 3, the page window side of the communication request includes the following steps:

step 301, when the second page determines that the loading is completed, invoking a window loading callback function, so that the first page registering the window loading callback function sends a communication registration request to the second page when detecting that the window loading callback function is invoked.

The window loading callback function refers to a function which is registered in the second page and used for indicating whether the second page is loaded or not, wherein the function is used for opening the first page of the second page by calling a page opening function. For example, the window load callback function may be a window.

It should be noted that, if the first page sends information to the second page before all elements in the second page are not loaded, an error may occur when the unloaded elements need to be referred to. Therefore, when the second page is loaded, the window loading callback function is called immediately to notify the first page that the second page is loaded, and a communication registration request can be sent to the second page.

Step 302, when detecting that the message receiving callback function is called, the second page acquires a calling parameter of the message receiving callback function.

And the message receiving callback function of the second page is registered when the second page is loaded and is used for receiving the information sent to the second page by other pages. For example, the message receive callback function may be a window.

It should be noted that, when the second page receives information sent by another page, the message receiving callback function of the second page is called, a parameter of the delivery information function called when the other page sends information to the second page is acquired, and the acquired parameter of the delivery information function is used as a calling parameter of the message receiving callback function of the second page.

Step 303, the second page determines whether the first check code in the calling parameter is legal.

The first check code is used for proving the validity of the first page so as to avoid establishing connection between an illegal page and the second page and ensure network security. The first check code may be included in a communication registration request sent by the first page requesting to establish a communication connection with the second page, and the communication registration request further includes a page parameter of the first page.

It should be noted that the call parameter of the message receiving callback function of the second page is determined according to the parameter of the delivery information function called by the first page for sending information to the second page, and the parameter of the delivery information includes information to be sent, the type of the information to be sent, the current state of the call page, and the parameter information of the call page.

Further, a password character string for verifying whether the first check code is legal can be preset, and whether the first check code is legal is judged according to whether the first check code is consistent with the preset password character string. That is, in a possible implementation form of the embodiment of the present disclosure, the step 303 may include:

and the second page judges whether the first check code is matched with a preset second check code corresponding to the first page identifier.

It should be noted that, in a possible implementation form of the embodiment of the present disclosure, different pages may preset different second check codes, that is, a password character string for verifying whether the first check code is legal, and cache the second check code corresponding to each page with the identifier of the page as an index, so as to avoid establishing a connection between an illegal page and a second page, and further improve the security of communication between page windows.

Specifically, if the first check code is matched with the second check code corresponding to the first page identifier, it may be determined that the first check code is legal; if the first check code is not matched with the second check code corresponding to the first page identifier, it can be determined that the first check code is illegal, and the communication registration request of the first page is rejected.

And 304, if the second page is legal, the second page acquires the window object of the first page according to the first page parameter in the calling parameters.

In this disclosure, if the second page determines that the first check code is valid, a communication connection may be established with the first page, and according to a page parameter of the first page in the call parameter, a window object of the first page is obtained, and a variable corresponding to the first page is set, and the window object of the first page is cached in the variable corresponding to the first page, so that the second page may send information to the first page according to the window object of the first page. For example, the variable name of the set variable corresponding to the first page may be fasternow.

According to the page window communication method provided by the embodiment of the disclosure, when the second page determines that loading is completed, the window loading callback function is called, so that a first page of the registered window loading callback function sends a communication registration request to the second page when the window loading callback function is detected to be called, the second page acquires the calling parameter of the message receiving callback function when the message receiving callback function is detected to be called, and the second page acquires the window object of the first page according to the first page parameter in the calling parameter when the first check code in the calling parameter is determined to be legal. Therefore, the second page informs the first page through the window loading calling function, the loading is completed, so that the first page sends a communication registration request to the first page, the window object of the first page is obtained according to the calling parameter of the message receiving callback function, and then the first page and the second page can send information to the opposite side by using the window object of the opposite side, so that the two-way communication between page windows is realized, and the user experience is improved.

Fig. 4 is a signaling interaction diagram of a page window communication method according to an embodiment of the disclosure.

As shown in fig. 4, the page window communication method includes the following steps:

step 401, the first page calls a page opening function by using the second page parameter to be communicated, so as to obtain the window object of the second page.

Step 402, the second page registers the message receiving callback function in the loading process.

And step 403, when the second page determines that the loading is completed, calling a window loading callback function.

In step 404, the first page sends a communication registration request to the second page when detecting that the load callback function is called.

The communication registration request comprises a first check code and a page parameter of a first page, so that when the second page determines that the first check code is legal, a window object of the first page is obtained according to the page parameter of the first page.

Step 405, when detecting that the message receiving callback function is called, the second page acquires a calling parameter of the message receiving callback function.
