How to override a function in another javascript file?
提问by Jishnu A P
I have a JavaScript file, Mybasefile.js, which has the function Mybasefunction(). I want to override this function in another JavaScript file. When the function is called in a button click, I want the original Mybasefunction()to be executed along with some other code. How can I do this?
我有一个 JavaScript 文件Mybasefile.js，它具有Mybasefunction(). 我想在另一个 JavaScript 文件中覆盖这个函数。当在按钮单击中调用该函数时，我希望原始Mybasefunction()代码与其他一些代码一起执行。我怎样才能做到这一点？
回答by Horia Dragomir
place this code in the override file. Make sure the override file is included after the orginal one.
将此代码放在覆盖文件中。确保覆盖文件包含在原始文件之后。
var orig_Mybasefunction = window.Mybasefunction;
window.Mybasefunction = function(){
orig_Mybasefunction();
...
}
