从jQuery对象中删除函数

Question

How can I remove a function from a jquery object? For example, I have

$('#element').func = function() {
     // function body goes here
}

And later on I want to remove func from $('#element') . I've tried delete but it doesn't work. Thanks.

Answer 1

How about this?

$('#element').fn.func = null;

or

$('#element').prototype.func = null;

or

delete $('#element').fn.func;

or

delete $('#element').prototype.func;

For understanding what the prototype is, have a look here: How does JavaScript .prototype work?

Answer 2

您可以通过分配null来完成。

$('#element').fn.func = null;
