列出jQuery中的所有直播活动 [英] List all live events in jQuery

问题描述

我如何在jQuery中找到哪些事件与特定元素的实时绑定？

How could I find in jQuery what events are bound with live for a particular element?

假设我有一个函数， randomFunction ，从函数数组中返回一个随机函数。如何找到哪个函数绑定到某个元素？

Say I have a function, randomFunction, that returns a random function from an array of functions. How can I find which function has been bound to a certain element?

var arrayOfFunctions = []; //a whole bunch of functions
function randomFunction(array){}; //returns one of those functions
$('#certain_element').live('click', randomFunction(arrayOfFunctions));

与 live for $（'＃certain_element'）？

推荐答案

好吧，想通了。
对于单击事件，对于 $（'＃certain_element'），将每个绑定的索引记录到console：

Alright, figured it out. For a click event, for $('#certain_element'), logging each binding's index to the console:

var relevantHandlers = $.map($(document).data('events').live, function(value){
  if(value.origType == 'click' && value.selector == '#certain_element'){
    return value.handler;
  }
}; //all handlers for #certain_element bound to click by live.
$.each(relevantHandlers, function(){
  console.log("the index is: " + $.inArray(this, arrayOfFunctions));
});
