Mootools扩展了“功能"功能.具有“扩展"类别的类.使jQuery无法使用的方法 [英] Mootools extends the "Function" class with an "extend" method making jQuery unusable

问题描述

Mootools扩展了"Function"类，并在其中添加了一个名为"extend"的新方法.现在，jQuery尝试使用jQuery.prototype.extend添加"extend"功能.但是，由于"extend"已经是jQuery对象的一部分(因为jQuery是Function类的对象)，所以jQuery.prototype.extend不起作用. 有人在同时使用Mootools和jQuery时遇到过这种冲突吗?

Mootools extends the "Function" class and adds a new method called "extend" in it. Now jQuery tries to add "extend" function using jQuery.prototype.extend. However since "extend" is already a part of the jQuery object (since jQuery is an object of the Function class) so jQuery.prototype.extend doesn't work. Did anyone come across this conflict while using Mootools and jQuery simultaneously ?

更笼统地说，如果扩展了诸如函数，数组或对象"之类的本机类，我们是否有办法恢复为原始定义?

More generically, if a native class like "Function or Array or Object" is extended, do we have a way to revert back to the original definitions ?

推荐答案

我认为做到这一点的唯一方法:

The only way I can think to do that:

<script type="text/javascript">
    // copy the original function
    var ext = Function.prototype.extend;
    // remove it
    delete Function.prototype.extend;
</script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script> 

<script type="text/javascript">
    // Copy the jQuery version
    var jqext = jQuery.prototype.extend;
    // remove it (for sanity).
    delete jQuery.prototype.extend;

    // reassign the original function.
    Function.prototype.extend = ext;
    // remove the jQuery extend method (now the original Function.extend method)
    delete jQuery.prototype.extend;
    // reassign jQuery's original extend method.
    jQuery.prototype.extend = jqext;
</script>
