jquery-确保事件处理程序最后在处理程序链中执行

我认为没有办法直接操纵订单。

看看这个: How to order events bound with jQuery

我的解决方案( http://jsfiddle.net/968jj/1345/ ):

 $.fn.lastHandler = function (events, handler) {
     var element = $(this);
     events = events.split(' ');
     for (var evt in events) {
         var event = $(element).data("events")[events[evt]];
         var hsucess = null;
         $.each(event, function (i, h) {
             if (h.handler == handler) {
                 hsucess = h;
             }
         });
         var index = event.indexOf(hsucess);
         if (index > -1) {
             event.splice(index, 1);
             event.push(hsucess);
         }
     }
 }

用途:

$(function() {

   var m1 = function(){ alert("mouseover to be the last"); };
   var m2 = function(){ alert("mouseover to be the first"); };
   var m3 = function(){ alert("mouseover to be the second"); };
   $("#el").mouseover(m1);
   $("#el").mouseover(m2);
   $("#el").mouseover(m3);

   $("#el").lastHandler('mouseover',m1);

});

用一些HTML

<DIV ID=“el”></DIV>

一些CSS

DIV宽度:200px;高度:200px;背景色:红色;

您可以将其用于任何一个或多个事件:

$("#el").lastHandler('keypress keyup change',fnHandler);
$("#el").lastHandler('click mouseover',fnHandler);
