jQuery中的ajaxStop()和ajaxComplete()函数之间有什么区别？
ajaxStop()方法
每当所有AJAX请求结束时，ajaxStop(callback)方法都会附加一个要执行的函数。
这是此方法使用的所有参数的描述-
callback- 要执行的功能。
假设我们在result.html 文件中包含以下HTML内容：
<h1>THIS IS RESULT...</h1>
示例
以下是显示此方法用法的示例：
<html>
<head>
<title>jQuery ajaxStop() 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 complete */
$(document).ajaxComplete(function(event,request,settings){
count++;
$("#stage3").html("<h1>Completes, Count :" + count + "</h1>");
});
/* Gets called when all requests are ended */
$(document).ajaxStop(function(event,request,settings){
count++;
$("#stage4").html("<h1>Stops, Count :" + count + "</h1>");
});
});
</script>
</head>
<body>
<p>Click on the button to load result.html file:</p>
<div id = "stage0" style = "background-color:blue;">
STAGE - 0
</div>
<div id = "stage1" style = "background-color:blue;">
STAGE - 1
</div>
<div id = "stage2" style="background-color:blue;">
STAGE - 2
</div>
<div id ="stage3" style = "background-color:blue;">
STAGE - 3
</div>
<div id = "stage4" style = "background-color:blue;">
STAGE - 4
</div>
<input type = "button" id = "driver" value = "Load Data" />
</body>
</html>ajaxComplete()方法
AJAX请求完成时，ajaxComplete(callback)方法将附加一个要执行的函数。
这是此方法使用的所有参数的说明：
callback- 要执行的功能。用于该请求的XMLHttpRequest和设置将作为参数传递给此函数。
假设我们在result.html文件中具有以下HTML内容：
<h1>THIS IS RESULT...</h1>
