问题描述

我有一个JavaScript文件， Mybasefile.js ，其函数为 Mybasefunction（）。我想在另一个JavaScript文件中覆盖此函数。在按钮单击中调用该函数时，我希望原始 Mybasefunction（）与其他一些代码一起执行。我该怎么做？

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?

推荐答案

将此代码放在覆盖文件中。确保在原始文件之后包含覆盖文件。

place this code in the override file. Make sure the override file is included after the orginal one.

var orig_Mybasefunction = window.Mybasefunction;
window.Mybasefunction = function(){
    orig_Mybasefunction();
    ...
}
