JS implements ajax call background definition (with code)

This time I will bring you JS to implement ajax call background definition (with code). What are the precautions for JS to implement ajax call background definition. The following is a practical case, let's take a look.

1. First we create an antzone.aspx page.

2. Create the following function in its cs file:

public static string mytest(string first, string second) 
{ 
  return return first+second; 
}

2. The html code is as follows:

<form id="myform" runat="server"> 
<p> 
 <asp:Button ID="bt" runat="server" Text="点击测试" /> 
</p> 
</form>

3.javascriptThe code is as follows:

$(function(){ 
 $("#bt").click(function(){ 
  $.ajax({ 
   type:"Post", 
   url:"antzone.aspx/mytest", 
   data:"{'first':'PHP','second':'欢迎您'}", 
   contentType:"application/json;charset=utf-8", 
   dataType:"json", 
   success:function(data){ 
    //返回的数据用data.d获取内容 
    alert(data.d); 
   }, 
   error:function(err){ 
    alert(err); 
   } 
  }); 
  //禁用按钮的提交 
  return false; 
 }); 
});
