Call ajax in jQuery to achieve asynchronous implementation

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>
