  VAR XHR = $阿贾克斯（{
    键入：POST，
    网址：some.php
    数据：名称=约翰和放大器;位置=波士顿，
    成功：函数（MSG）{
       警报（数据保存：+味精）;

            VAR XHR; //全局对象

            功能your_function（）{
                如果（XHR＆安培;＆安培;！xhr.readystate = 4）{
                    xhr.abort（）;
                }

                XHR = $阿贾克斯（{
                    键入：POST，
                    网址：some.php
                    数据：名称=约翰和放大器;位置=波士顿，
                    成功：函数（MSG）{

        }）;
 

Is it possible to abort a previously-running Ajax request?

var xhr = $.ajax({
    type: "POST",
    url: "some.php",
    data: "name=John&location=Boston",
    success: function(msg){
       alert( "Data Saved: " + msg );
    }
});

解决方案

try something like this

        $(document).ready(function(){
            var xhr; // global object

            function your_function() {
                if(xhr && xhr.readystate != 4){
                    xhr.abort();
                }

                xhr = $.ajax({
                    type: "POST",
                    url: "some.php",
                    data: "name=John&location=Boston",
                    success: function(msg){
                       alert( "Data Saved: " + msg );
                    }
                });
            }
        });
