要处理jQuery AJAX成功事件，请使用ajaxSuccess()方法。只要AJAX请求成功完成，ajaxSuccess(callback)方法就会附加一个要执行的函数。这是一个Ajax事件。
这是此方法使用的所有参数的描述-
callback- 要执行的功能。事件对象，XMLHttpRequest和用于该请求的设置将作为参数传递给回调。
假设我们在result.html中具有以下HTML内容-
<h1>THIS IS RESULT...</h1>
以下是显示此方法用法的示例-
<html>
<head>
<title>jQuery ajaxSuccess() method</title>
<script src = "https://cdn.staticfile.org/jquery/3.2.1/jquery.min.js"></script>
<script>
$(document).ready(function() {
/* Global variable */
var count = 0;
$("#driver").click(function(event){
$('#stage0').load('result.html');
});
/* Gets called when request starts */
$(document).ajaxStart(function(){
count++;
$("#stage1").html("<h1>Starts, Count :" + count + "</h1>");
});
/* Gets called when request is sent */
$(document).ajaxSend(function(evt, req, set){
count++;
$("#stage2").html("<h1>Sends, Count :" + count + "</h1>");
$("#stage2").append("<h1>URL :" + set.url + "</h1>");
});
/* Gets called when request completes */
$(document).ajaxComplete(function(event,request,settings){
count++;
$("#stage3").html("<h1>Completes,Count:" + count + "</h1>");
});
/* Gets called when request is stopped */
$(document).ajaxStop(function(event,request,settings){
count++;
$("#stage4").html("<h1>Stops, Count :" + count + "</h1>");
});
/* Gets called when all request completes successfully */
$(document).ajaxSuccess(function(event,request,settings){
count++;
$("#stage5").html("<h1>Success,Count :" + count + "</h1>");
});
});
</script>
</head>
