一个简单的ajax操作

由于公司接下来的项目 会不断用到ajax！

因此好好研究了下。

基本操作 挺简单的！

HTML：

    <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文件：

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("未知错误！"); 
                }, 
                success:function(data){
                    var msg ="未知错误!";

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

        Response.ContentEncoding = System.Text.Encoding.UTF8;       
        Response.Write("{\"result\":"+_StausCode+"}");
        Response.End();
    }

    public bool PostComment()
    {
        WXCommentInfo comment = new WXCommentInfo();
        comment.CommentTitle = _title.ToString();
        comment.CommentContent = _content.ToString();

        return Comment.AddComment(comment);
    }
}
