Along with the raising of the performance of browser, the application of java script in the Internet project is more and more extensive, and code quantity and the complexity thereof of java script are also doubled and redoubled thereupon.Due to historical reasons, there is open global variable in java script, the defects such as incomplete Object-Oriented Design, and innately lack external reference mechanism and modularization mechanism, bring many difficulties to developing and debugging large-scale java script program like this.
A lot of technology attempts the technical problem solving the large-scale java script of exploitation.Such as Require.js and sea.js, the method that they all adopt java script dynamically to add document label realizes the asynchronous download of js, by stating the dependence to other library files in java script file, reach the java script documentation of complexity is divided into can be multiplexing multiple modules, thus the modularization of the js file realized.
The common feature of these methods is: the code of user needs to encapsulate by fixed mode, the specification making it meet modularization to call; Need to rely on declaration module; By the dynamic load of the js file of outside.
Such as in Require.js, can be just the module of " logger " with define function definition ID, like this inside other code, just can utilize Require.js function to call " logger " module.Then " logger " module become realize js file can be multiplexing module.
The problem of prior art is to need the modular functionality originally do not possessed to realize java script the java script script to user writes to encapsulate and rewrite, make it to meet modular specification, so that as the module that can arbitrarily call.Extra code and amendment can increase the complexity of program, and encapsulation and the logic that loads likely are brought program and can not be estimated and uncontrollable impact.What not only increase code writes difficulty, simultaneously can bring compatibility issue to original code write.
Another one problem is the difficulty that modular dynamic load can cause debugging.First the loading sequence of code is no longer controlled, due to load mechanism be different for the control of the loading sequence of dependent file, the program called or triggered after needing to have loaded for some, must the problem of extra consideration loading sequence.Secondly the action scope in order to make code meet the rewriting meeting reprogramming internal variable sum functions that modularization is carried out, when debugging, error message will become and be difficult to follow the trail of.
