使用jQuery获取当前事件处理程序的值

问题描述

我可以通过调用

  $（'＃id'）来设置onclick处理程序。 {
 console.log（'click！'）; 
}）; 
  

同样使用jQuery，我如何获得对当前处理click（）事件？

原因是我有另一个对象，并且想要将其点击处理程序设置为与#id相同的一个。

更新

感谢您的所有建议。问题是我不知道哪个函数正在处理点击。跟踪它会将状态添加到已经很复杂的模板编辑系统中。 jQuery的 .click （函数）方法将函数添加到在click事件中执行的队列中〜所以实际上拉出了给定函数的引用可能会比你期望的要多毛。

正如其他人指出的那样，最好传递一个函数引用;然后你已经有了你需要的引用。

  var clicky = function（）{/ * do stuff * /}; 
 $（'＃id'）。click（clicky）; 
 //用clicky 
做其他事情 

更新

如果你真的需要把它弄出来，试试这个：

  jQuery._data（document.getElementById （'id'））。events.click [0] .handler 
  

取决于您的jQuery版本这可能会或可能不会工作〜尝试玩弄

  jQuery._data（document.getElementById（'id'））
  

并且看看您得到了什么。

得到来自这部分来源的想法：

I can set the onclick handler using jQuery by calling

$('#id').click(function(){
   console.log('click!');
});

Also using jQuery, how can I get a reference to the function which is currently handling the click() event?

The reason is that I have another object and want to set its click handler to the same one as #id.

Update

Thank you for all the suggestions. The problem is that I do not know which function is currently handling the clicks. Keeping track of it would add state to an already complicated template-editing system.

解决方案

jQuery's .click(function) method adds the function to a queue that is executed on the click event~

So actually pulling out a reference to the given function would probably be hairy-er than you expect.

As noted by others, it would be better to pass in a reference to the function; and then you already have the reference you need.

var clicky = function () { /* do stuff */ };
$('#id').click(clicky);
// Do other stuff with clicky

Update

If you really really need to get it out, try this:

jQuery._data(document.getElementById('id')).events.click[0].handler

Depending on your version of jQuery that may or may not work~ Try playing around with

jQuery._data(document.getElementById('id'))

and see what you get.
