thinkphp中ajax与php响应过程详解

<a href="javascriptvoid(0);" id= "<php>echo $val[id]</php>" class="delete" >删除</a>

jQuery(".list a.delete").click(function(){
            if(confirm("你确定要删除吗？")){
                var _this=this;
                var id = jQuery(_this).attr("id");
                jQuery.ajax({
                    url : '/Search/index.php/Jason/delete?',
                    data : {'id':id},
                    dataType : 'json',
                    suess : function(data){
                        var del = data.del;
                        if(del == 1){//删除成功
                            jQuery("#"+id).parents(".list").remove();
                        }else{//删除失败
                            alert("删除失败");
                        }
                    }
                });
            }
});

public function delete(){ 
        if($this->isGet()){ 
            $userId = session("uid");//用户登录 
            if(!empty($userId)){ 
                $a = M(''); 
                $id = $this->_get('id'); 
                $result=$a->where("id=$id")->delete();//删除 
                if($result > 0){ 
                    $arr = array("del"=>'1'); 
                }else{ 
                    $arr = array("del"=>'0'); 
                } 
                $json_str = json_encode($arr); 
                echo $json_str;//返回给js 
            } 
        } 
}

if(del == 1){//删除成功 
     jQuery("#"+id).parents(".list").remove();//这句话就是后台删除成功后，直接在前台对响应的div进行删除，这样性能就会很快，无需进行后台数据的重新提取至前台页面中， 
 }else{//删除失败 
     alert("删除失败"); 
}

jQuery("#"+id).parents(".list").remove();

jQuery("#"+id).parents(".list").slideUp("slow", function(){ 
      jQuery(this).remove(); 
});
