This time I will bring you the precautions for calling ajax in jQuery to achieve asynchronous implementation, and the precautions for calling ajax in jQuery to achieve asynchronous implementation. The following is a practical case, let's take a look.
<script type="text/javascript" language="javascript" src="JS/jquery-1[1].2.3.min.js"></script> <script type="text/javascript" language="javascript"> $(document).ready(function(){ //Jquery 页面加载事件,当页面加载之后首先执行这个方法 //第一种Ajax请求 $.ajax({ type:"GET", //请求类型,有get,post等类型,和表单提交是一样的 url:"Result.aspx", //请求处理的页面,就是说由那个页面捕获请求,同样这个路径可以换成ashx,一般处理程序 data: "name=John&location=Boston", //传递参数,实在就是(Result.aspx?name=John&loaciton=Boston) success:function(msg){ //请求成功会由这个方法处理,其中请求成功返回值由msg接收 $("#ajaxp").text(msg); } }); //第二种请求 $.get( //用get请求方式,其实就是上一种的变体 "Handler.ashx", {name:"笨笨熊",sex:"女"}, //要传递的参数,解析为(Handler.ashx?name=笨笨熊&sex=女) function(msg){ //请求返回参数 $("#p1").text(msg); } ); //第三种请求 $.post( //这种请求的上一种是一样的,只是请求方式不同 "Handler2.ashx", {name:"benben 笨笨熊",sex:"女"}, function(msg){ $("#p2").text(msg); } ); //第四种请求 $.getJSON( //这种是用JSON 实现的,JSON是一种通用的数据格式 "Handler3.ashx", //路径 {name:"aaa"}, //传递参数 function (data){ //回调处理函数 返回的就是json数据格式,由data接收这串数据 var str=""; //下面就是解析这些数据,具体接送的使用但不做考虑,设计内容很多,一时无法讲解 str+="姓名: "+data.name+"<br/>"; str+="性别: "+data.sex+"<br/>"; str+="地址: "+data.address+"<br/>"; $("#p3").html(str); } ); }); </script>
