jquery(ajax)与js(ajax)的比较

原始js：

 1 function update_mess(){
 2     var account_name = $("#account").val();
 3                     var xmlhttp;
 4                     if(window.XMLHttpRequest){
 5                         xmlhttp = new XMLHttpRequest;
 6                     }
 7                     else{
 8                         xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
 9                     }
10                     xmlhttp.onreadystatechange = function(){
11                         if(xmlhttp.readyState == 4 && xmlhttp.status == 200){
12                             var json = eval("("+ xmlhttp.responseText +")");
13                             if(json.returnedjson.infostatus == 'T'){
14                                 alert(json.returnedjson.infomsg);
15                                 location.reload();
16                             }
17                             else{
18                                 alert(json.returnedjson.infomsg);
19                             }
20                         }
21                     }
22                     var str = "account_id=" + account_id;
23                     xmlhttp.open("post", "/update_mess_action", true);
24                     xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
25                     xmlhttp.send(str);
26 }

 

ajax提交方式比js原始的提交方式更为简介，具体如下：

 1 $.ajax({
 2         type:"post",
 3         url:"find_password_action?account_name="+ account_name + "&account_answer1=" + account_answer1 + "&account_answer2=" + account_answer2,
 4         success:function(date){
 5             var json = eval("("+ date +")");
 6             if(json.returnedjson.infostatus == "T"){
 7                 //alert(json.returnedjson.infomsg);
 8                 $("#mymodal1").modal("toggle");
 9             }
10             else{
11                 alert(json.returnedjson.infomsg);
12             }
13         },
14         error:function (date){
15             alert("找回密码失败！");
16         },
17     });

两种差不多，但是jquery的ajax更加灵活，对于post没有那么多的限制。
