一個簡單的ajax操作

由於公司接下來的項目 會不斷用到ajax！

因此好好研究了下。

 

基本操作 挺簡單的！

 

HTML：

代碼

    <form id="form1" runat="server">
<div>
<input type="text" id="commentTitle" /><br />
<textarea id ="commentBody" rows="10" cols="20"></textarea><br />
<input type="button" id="btnsummit" value="提交" onclick="atPost();" />
</div>
</form>

 

JS檔案：

代碼

function atPost(){
var commentTitle=$("#commentTitle").val();
var commentBody =$("#commentBody").text();

            $.ajax({
                type:"POST",
                url:"atPost.aspx",
                data:"commentTitle="+commentTitle+"&commentBody="+commentBody,
                dataType:"json",
                error:function(){
                    alert("未知錯誤！"); 
                }, 
                success:function(data){
var msg ="未知錯誤!";

switch(data.result){
case 0:
                            msg="提交失敗！";
break; 
case 1:
                            msg="提交成功！"; 
break;
case 2:
                            msg="Code錯誤！";
break;
default:
                            msg=data.result;
break;       
                    }
                    alert(msg);
                }  
            });
        }
