Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The method for switching the document page provided by the embodiment of the invention can be applied to any electronic equipment needing to switch the document page, and is not particularly limited herein. For convenience of description, the electronic device is hereinafter referred to simply as an electronic device.
As shown in fig. 1, a specific processing flow of the method for switching document pages provided by the embodiment of the present invention includes:
step S101, a page switching instruction for the current document is obtained, wherein the page switching instruction comprises a target page identifier.
The embodiment of the invention can be applied to various electronic devices, such as: computers or mobile terminals, etc.
In practice, the electronic device may obtain a page switching instruction for the current document, where the page switching instruction may include the target page identifier.
Step S102, obtaining a target page from the page loaded in the memory according to the target page identifier included in the page switching instruction.
In an implementation, the target page may have been previously loaded in the memory, and the target page may be obtained from the memory according to the target page identifier included in the page switching instruction.
In step S103, the target page of the document is switched to the current page.
Step S104, taking the current page as a reference page, and loading the page after the reference page into the memory until the utilization rate of the memory by the current program reaches a preset threshold value of the utilization rate of the memory by the current program, wherein the current program is a program for opening the current document.
In the embodiment of the invention, the page behind the reference page can be preloaded after each page switching, so that the target page can be obtained from the page loaded in the memory when the page switching is carried out next time.
In an implementation manner, the threshold of the memory usage rate of the current program may be preset, and specifically, in order to enable the electronic device to have enough memory space for running other programs, the threshold of the memory usage rate of the current program may be set to 30%.
Therefore, when the user switches the document page, the method and the device do not need to load the content of the document target page into the memory of the computer or the RAM of the mobile terminal from the ROM or the Flash of the hard disk of the computer or the mobile terminal according to the page switching instruction, and then obtain the target page from the memory of the computer or the RAM of the mobile terminal; but according to the page switching instruction, the page switching instruction is directly loaded in the memory in advance, such as: the target page is obtained from the page in the RAM of the computer or the RAM of the mobile terminal, and the switching speed of switching from the current page to the target page is improved.
Specifically, the specific implementation process of step S101 in the embodiment shown in fig. 1 can be seen in fig. 2. Fig. 2 is a specific flowchart of step S101 in the embodiment shown in fig. 1, which includes:
step S201, judging whether the user clicks the page switching key of the current document or executes the page up and down sliding operation.
The electronic device may determine whether the user clicks a page switch button of the current document or performs a page up/down sliding operation.
If the result is yes, i.e. the user clicks the page switching key of the current document or performs the page up/down sliding operation, then step S202 is performed; if the judgment result is negative, namely the user does not click the page switching key of the current document or execute the page up and down sliding operation, the operation is ended.
Step S202, determining a target page according to user operation, and obtaining a target page identifier.
Step S203, a page switching instruction including the target page identifier is generated.
The process of generating a page switch instruction containing a target page identifier shown in fig. 2 can be applied to various electronic devices, for example: computers or mobile terminals, etc.
Another flowchart of the method for switching document pages provided in the embodiment of the present invention, as shown in fig. 3, includes:
step S301, a page switching instruction for the current document is obtained, wherein the page switching instruction comprises a target page identifier.
The specific implementation process of this step may be the same as the process shown in fig. 2, and is not described here again.
Step S302, obtaining a target page from the page loaded in the memory according to the target page identifier included in the page switching instruction.
Step S303, the target page of the document is switched to the current page.
Step S304, obtaining the current utilization rate of the current program for opening the current document to the memory.
Specifically, if the computer is used, the current utilization rate of the memory by the current program can be obtained by reading the memory occupied by the current program in the task management; if the mobile terminal is the mobile terminal, the current utilization rate of the memory by the current program can be obtained by reading the memory occupied by the current program in the storage space information and calculating.
In step S305, the remaining amount of the current total memory is obtained.
The method includes the following steps that (1) the implementation can be carried out, specifically, if the computer is used, the residual amount of the current total internal memory can be obtained through reading the internal memory occupied by each program in task management; if the mobile terminal is the mobile terminal, the residual amount of the current total memory can be obtained by reading the memory occupied by each program in the storage space information.
Step S306, determine whether the remaining amount of the current total memory is smaller than a preset threshold of the memory usage rate of the current program.
If the determination result is yes, that is, the remaining amount of the current total memory is smaller than the preset threshold of the memory usage rate of the current program, executing step S307; if the determination result is negative, that is, the remaining amount of the current total memory is not less than the preset threshold of the memory usage rate of the current program, step S308 is executed.
Step S307, the remaining amount of the current total memory is used as a preset threshold of the memory usage rate of the current program.
In this case, the remaining amount of the current total memory may be used as the preset threshold of the current program for the memory usage rate.
Step S308, determine whether the current utilization rate of the memory by the current program reaches a preset threshold of the memory utilization rate by the current program.
If the judgment result is yes, namely the current utilization rate of the current program to the memory reaches a preset threshold value of the current program to the memory utilization rate, ending the operation and waiting for the next operation instruction; if the determination result is negative, that is, the current usage rate of the memory by the current program is smaller than the preset threshold of the usage rate of the memory by the current program, step S309 is executed.
Step S309, determine whether there is an unloaded page after the page of the loaded current document in the memory.
If the determination result is yes, that is, there is an unloaded page after the page of the loaded current document in the memory, executing step S310; if the judgment result is negative, namely no unloaded page exists after the loaded page of the current document in the memory, ending the operation and waiting for the next operation instruction.
Step S310, sequentially loading the pages subsequent to the loaded page until the utilization rate of the memory by the current program reaches the threshold.
The page after the loaded page may be sequentially loaded until the usage rate of the memory by the current program reaches the threshold, and certainly, the page after the loaded page is sequentially loaded, and when all the pages of the current document are loaded into the memory and do not reach the threshold, the loading is stopped, the operation is ended, and a next operation instruction is waited.
Therefore, when the user switches the document page, the method and the device do not need to load the content of the document target page into the memory of the computer or the RAM of the mobile terminal from the ROM or the Flash of the hard disk of the computer or the mobile terminal according to the page switching instruction, and then obtain the target page from the memory of the computer or the RAM of the mobile terminal; but directly from the pre-loaded memory according to the page switch instruction, such as: the target page is obtained from the page in the RAM of the computer or the RAM of the mobile terminal, and the switching speed of switching from the current page to the target page is improved.
In addition, in this embodiment, the remaining amount of the current total memory may be obtained in advance, so that the memory occupied by page loading does not exceed the remaining amount of the total memory, and the problems of system crash and the like may be avoided.
Still another flowchart of the method for switching document pages provided in the embodiment of the present invention, as shown in fig. 4, includes:
step S401, a page switching instruction for the current document is obtained, wherein the page switching instruction comprises a target page identifier.
The specific implementation process of this step may be the same as the process shown in fig. 2, and is not described here again.
Step S402, obtaining a target page from the page loaded in the memory according to the target page identifier included in the page switching instruction.
In step S403, the document target page is switched to the current page.
Step S404, obtaining the current utilization rate of the current program for opening the current document to the memory.
In step S405, the remaining amount of the current total memory is obtained.
Step S406, determine whether the remaining amount of the current total memory is smaller than a preset threshold of the memory usage rate of the current program.
If the determination result is yes, that is, the remaining amount of the current total memory is smaller than the preset threshold of the memory usage rate of the current program, executing step S407; if the result of the determination is negative, that is, the remaining amount of the current total memory is not less than the preset threshold of the memory usage rate of the current program, step S408 is executed.
Step S407, the remaining amount of the current total memory is used as a preset threshold of the memory usage rate of the current program.
In step S408, it is determined whether the current utilization rate of the memory by the current program reaches a preset threshold of the memory utilization rate by the current program.
If the determination result is yes, that is, the current utilization rate of the memory by the current program reaches the preset threshold value of the current utilization rate of the memory by the current program, then step S409 is executed; if the determination result is negative, that is, the current utilization rate of the memory by the current program is smaller than the preset threshold of the current utilization rate of the memory by the current program, step S410 is executed.
Step S409, determining whether there is an unloaded page after the page of the loaded current document in the memory.
If the determination result is yes, that is, there is an unloaded page after the page of the loaded current document in the memory, execute step S412; if the judgment result is negative, that is, there is no unloaded page behind the page of the loaded current document in the memory, the operation is ended, and a next operation instruction can be waited.
In step S410, it is determined whether there is an unloaded page after the page of the loaded current document in the memory.
If the determination result is yes, that is, there is an unloaded page after the page of the loaded current document in the memory, executing step S411; if the judgment result is negative, that is, there is no unloaded page behind the page of the loaded current document in the memory, the operation is ended, and a next operation instruction can be waited.
Step S411, sequentially loading the pages subsequent to the loaded page until the utilization rate of the memory by the current program reaches the threshold.
In step S412, it is determined whether the page following the reference page has been loaded with less than the preset minimum number of preloaded pages.
It may be implemented that the preset minimum number of preloaded pages may be 20 pages.
If the judgment result is negative, namely the page behind the reference page is loaded with the minimum pre-loaded page number which is not less than the preset minimum pre-loaded page number, ending the operation and waiting for the next operation instruction; if the judgment result is yes, that is, the page following the reference page has been loaded with less than the preset minimum number of preloaded pages, step S413 is executed.
In step S413, it is determined whether there is a loaded page before the reference page.
If the result of the determination is yes, that is, there is a loaded page before the reference page, step S414 is executed; if the judgment result is negative, namely the reference page has no loaded page before, ending the operation and waiting for the next operation instruction.
Step S414, sequentially deleting the pages farthest from the reference page, and releasing the memory occupied by the pages farthest from the reference page until the usage rate of the memory by the current program is less than the threshold.
In an implementation, the page farthest from the reference page may be sequentially deleted, and the memory occupied by the page farthest from the reference page is released until the utilization rate of the memory by the current program is less than the threshold.
After the step is executed, the step returns to the step S410, and the step of determining whether there is an unloaded page after the page of the current document loaded in the memory is executed.
Therefore, when the user switches the document page, the method and the device do not need to load the content of the document target page into the memory of the computer or the RAM of the mobile terminal from the ROM or the Flash of the hard disk of the computer or the mobile terminal according to the page switching instruction, and then obtain the target page from the memory of the computer or the RAM of the mobile terminal; but directly from the pre-loaded memory according to the page switch instruction, such as: the target page is obtained from the page in the RAM of the computer or the RAM of the mobile terminal, and the switching speed of switching from the current page to the target page is improved.
Moreover, in this embodiment, the remaining amount of the current total memory may be obtained in advance, so that the memory occupied by page loading does not exceed the remaining amount of the total memory, and the problems of system crash and the like are avoided.
In addition, in this embodiment, a minimum pre-loaded page number is also preset, and when a page is located before the reference page and a page loaded after the reference page is less than the minimum pre-loaded page number, the page before the reference page is deleted to ensure that the page after the reference page reaches the minimum pre-loaded page number, so that a situation that the page before the reference page occupies a memory so that the usage rate of the memory by the current program reaches the threshold value and a target page after the reference page is not loaded is avoided as much as possible, and a switching speed from the current page to the target page is ensured as much as possible.
