In order to solve the prior art in html page development process, need to load whole JavaScript moulds simultaneously
Then block calls required JavaScript module to assist opening for html page in the JavaScript module of load
The problem of hair, the loading method of this JavaScript module once need module to be loaded excessive, influence the speed of load.
The embodiment of the invention provides a kind of method and devices of dynamically load JavaScript module, and JavaScript mould can be improved
The loading velocity of block.
In order to solve above-mentioned prior art problem, a kind of dynamically load JavaScript module provided in an embodiment of the present invention
Method, this method comprises:
Receive dlm (dynamic loading module) instruction；It include: each module to be called in the dlm (dynamic loading module) instruction
Identification information；According to the identification information of each module to be called, loads in default first function library, is described each
The corresponding each first JavaScript module of the identification information of a module to be called, and it is each described in layout page
The module corresponding position to be called shows the identification information corresponding each first of each module to be called
JavaScript module.
It can be seen that the embodiment of the present invention, loads JavaScript module by the way of dynamically load, according to
Dlm (dynamic loading module) instruction, correlation module required for targetedly loading do not need the whole JavaScript module of load,
The loading velocity of JavaScript module can be improved to avoid excessive unwanted JavaScript module is loaded.
A kind of information interacting method based on barrage is provided for the embodiments of the invention first below to be introduced.
As shown in FIG. 1, FIG. 1 is a kind of dynamically load JavaScript modular approach provided in an embodiment of the present invention, the party
Method may include:
S110 receives dlm (dynamic loading module) instruction；It wherein, include: each to be called in dlm (dynamic loading module) instruction
The identification information of module.
In html page development process, needs to load and call JavaScript module to assist opening for html page
Hair.Wherein, which can be what rear end developer was pre-created, and different JavaScript modules is specific
Different identification informations.
In the embodiment of the present invention, the dlm (dynamic loading module) received for JavaScript module is instructed, the dynamically load mould
The identification information of each module to be called is contained in block instruction.Wherein, dlm (dynamic loading module) instruction is sent out by user
Out, which can be rear end developer etc..The mark for the module to be called for including in dlm (dynamic loading module) instruction
Know the targeted JavaScript module of information, it is either one or more, in the embodiment of the present invention, for the dynamic
The number of the identification information for the module to be called that loading module instruction is included is with no restriction.
In addition, the dlm (dynamic loading module) instructs, it can be rear end developer and edit in advance, and be stored in for software
In the device memory of exploitation.Dlm (dynamic loading module) instruction, is corresponding with the movement of execution, when needing to develop html page, after
End developer issues dlm (dynamic loading module) instruction, after the equipment for developing html page receives the instruction, is setting
The instruction is inquired in standby memory, and executes its corresponding movement.Certainly, the application is only illustrated with above-mentioned implementation,
Implementation in practical application for dlm (dynamic loading module) instruction is not limited to that.
S120 is loaded in default first function library, Ge Geyao according to the identification information of each module to be called
The corresponding each first JavaScript module of the identification information of called module, and each in layout page to be called
Module corresponding position, show the corresponding each first JavaScript module of identification information of each module to be called.
Optionally, each first JavaScript module in the default first function library are as follows: previously according to user
Demand is write and is saved.
In practical applications, which can compile for rear end developer previously according to user demand
It writes and saves, include multiple and different the first JavaScript module in the default first function library.It is a kind of optional
Implementation are as follows: can be in page development initial stage, demand of the rear end developer according to user to product, according to different functions
Demand analysis is carried out, each required function in the page is obtained and then for required function, writes comprising multiple and different
The first JavaScript module the first function library and save.
Wherein, it presets in the first function library, all specifically its is corresponding for each the first different JavaScript module
Identification information, and, the identification information of each the first different JavaScript module is user to default first function text
It is write and creates completion during being saved in part library.
In the embodiment of the present invention, each module to be called included in dlm (dynamic loading module) instruction is being received
It, can be according to the identification information of each module to be called, in default first function library, inquiry after identification information
With the identification information for the module to be called, the first JavaScript module with same identification information.In default first function
Can in library, inquire each first JavaScript module corresponding to the identification information of each module to be called it
Afterwards, the identification information of each module to be called is corresponding each in the default first function library that load is inquired
First JavaScript module.And in layout page each module corresponding position to be called, it to be called each
The corresponding each first JavaScript module of the identification information of module is shown.
Wherein, layout page can be, at page development initial stage, demand of the rear end developer according to user to product,
Edit the layout page generated.Or during page development, rear end developer is according to product demand, editor
The layout page of generation.Specifically, the generating mode of layout page, this is not restricted by the present invention.
Optionally, each module to be called all is corresponding with location information in the layout page, the location information parameter,
It can be added when generating the page layout, be also possible to included in the instruction of received dlm (dynamic loading module), this
When, the dlm (dynamic loading module) instruction in include: each module to be called identification information and each module to be called
Corresponding location information.Certainly, the application is only illustrated with above-mentioned implementation, each in layout page in practical application
The implementation of all corresponding location information of the module to be called is not limited to that.
It illustratively, may include multiple and different first in the embodiment of the present invention, in the default first function library
JavaScript module, multiple the first different JavaScript module can be expressed as multiple js files, each file pair
Answer a specific function.Such as: Tabs.js can be used to encapsulate the function of switch card effect, and Imgs.js can be used to encapsulate
The function of picture carousel, Wins.js can be used to encapsulate the function of floating frame, and Menus.js can be used to encapsulate multistage drop-down
