如何重命名javascript预定义函数 [英] How to rename javascript predefined functions

问题描述

是否可以像使用php一样重命名JavaScript中的预定义函数:

Is it possible to rename a predefined function in JavaScript as we do with php :

<?php
rename_function('mysql_connect', 'connect' );
?>

推荐答案

在js中也可能.请参阅此功能.

It's possible in js too. See this function.

function rename_function(obj, oldf, newf){
    obj[newf]=obj[oldf];
    delete obj[oldf];
}

此处obj是该函数的关闭.通常，如果您的函数没有闭包，则它位于window对象下. rename_function(window, 'alert', 'al')

Here obj is the closure of the function. Normally if your functions have no closure it's under window object. rename_function(window, 'alert', 'al')
