//如若上一次AJAX请求未完成，则中止请求

var queryTruckAjax;

        if(queryTruckAjax){

            queryTruckAjax.abort();

        }

        queryTruckAjax =  $.ajax({

            type: "POST",

            url:url,

            dataType: "json",

            success: function(data) {

              do thing...

            },error: function () { 

            }

        });

abort只是停掉本次请求不理会返回，应该不会影响你服务器端执行，应该是你服务器端代码有问题造成的

为什么不是等之前的执行完再执行本次的
jquery ajax abort()的使用方法
由于使用的是jquery,挡在手册里没有找到关于.abort()方法，在网上搜索了一下，在http://ooxx.me/jquery-ajax-abort.orz看到有关于jquery 里.abort()使用方法,直接用例子: 代码如下: current_request = $.get(‘/events’, { ‘七夕’: ‘发春’ },function(resp) { alert(resp); }); if(current_request) {current_request.abort();} 但是使用这个current_request.abort();方法取消的时候，实际上会触发$.a
IE6中ajax aborted错误请求中断解决方法
给a标签绑定了一个click事件用来触发ajax请求，在IE6中，请求时常会被中断，在其他浏览器中都一切正常。 在IE6中使用Fiddler2和httpWatch监视请求，经常会出现”aborted”，折腾了许久，相当的诡异。后来将a标签换成button，请求正常，最后经提醒，可能是a标签的默认事件中断了请求。但是，在HTML代码中，已经将a标签的href设置成了”[removed]void(0)”，通常这样是可以阻止默认事件了(页面跳转)。a标签的click事件会先执行，然后才执行href的跳转，如果href是一段javascript语句，这个时候就会执行。IE6在执行href的java

js与jQuery终止正在发送的ajax请求的方法
本文实例讲述了js与jQuery终止正在发送的ajax请求的方法。分享给大家供大家参考，具体如下： 核心：调用XMLHttpRequest对象上的abort方法 jquery的ajax方法有自己的超时时间设置参数： $.ajax({type:'POST', url:'b.php', data:'', timeout:5000, success:function(){ } }) 同时 1. $.get返回的数据类型是XMLHttpRequest，请参考手册。（$.post、$.ajax、$.getJSON、$.getScript也同样） 2. XMLHttpRequest
jQuery取消ajax请求的方法
本文实例讲述了jQuery取消ajax请求的方法。分享给大家供大家参考。具体分析如下： 这里需要注意的是，在ajax请求未响应之前可以用xhr.abort()取消，但如果请求已经到达了服务器端，这样做的结果仅仅是让浏览器不再监听这个请求的响应，但服务器端仍然会进行处理 var xhr = $.ajax({ type: "POST", url: "test.php", data: "name=test", success: function(msg){ alert( msg ); } }); //取消请求 xhr.abort() 希望本文所述对大家的jQuery程
