頁面代碼:

<div align="center">
  <p>用戶名：
    <input type="text" name="lid" id="lid" />
  </p>
  <p>密碼：
  <input type="text" name="pwd" id="pwd" />
  </p>  
  <p>
    <input type="submit" name="loginbt" id="loginbt" value="登 陸" />
  </p>
  <p><div id="state" name="state"></div></p>
</div>

 

Javascript代碼:(有兩種方法)

    $(document).ready(function(){
        $('#loginbt').click(function(){
            // case one :
            $.ajax({
                type:"POST",
                url:"../index.php/index/doAjax",
                data:{lid:$('#lid').val(),pwd:$('#pwd').val()},
                success:function(msg){
                            $('#state').html(msg);
                        }           
            });    
            // case two:
            
        });
    });

 

 後臺php代碼: 

class IndexAction extends Action
{
    public function index()
    {

    }
    
    public function doAjax()
    {
        $lid=$_POST["lid"];
        $pwd=$_POST["pwd"];
        if($lid==""||$pwd=="")
                echo '用戶名或密碼爲空！';
        else
        {
            if($lid=="admin" && $pwd=="admin")
                    echo '登陸成功！';
            else
                    echo '登陸失敗！';
        }
    }
}
