工作：新闻模块修改与删除操作

摘要：添加操作news/doAdd操作add.html $.post(url,data,function(data){})public function doAdd(){   // 获取数据         $data = Request::param

1. 添加操作news/doAdd操作

2. add.html $.post(url,data,function(data){})

public function doAdd(){
		  // 获取数据
        $data = Request::param();
        halt($data);
        // 加入发布的时间
        $data['time'] = time();
        // 加入发布新闻的管理员名称
        $data['username'] = Session::get('username');
        // 将新闻标题独立出来
        $title = $data['title'];
        // 将新闻标题作为条件来查询数据
        $news = NewsModel::where('title', "$title")->find();
        // 验证新闻标题是否重复
        if ($news == true) {
            // 重复并返回提示信息
            return ['res' => 0, 'msg' => '新闻标题重复！'];
        }
        // 实例化模型
        $new = new NewsModel();
        // 存储验证
        if ($new->save($data)) {
            // 返回发布成功的信息
            return ['res' => 1, 'msg' => '发布成功！'];
        } else {
            // 返回发布失败的信息
            return ['res' => 0, 'msg' => '发布失败！'];
        }
		
		
	}	

 
     form.on('submit(add)', function (data) {
            console.log(data);
            //发异步，把数据提交给php
            $.post('{:url(\'doAdd\')}', {
                'title': $('#title').val(),
                'desc': $('#desc').val(),
                'content': editor.txt.html(),
            }, function (data) {
                if (data.res == 1) {
                    layer.alert(data.msg, {icon: 6}, function () {
                        // 获得frame索引
                        var index = parent.layer.getFrameIndex(window.name);
                        //关闭当前frame
                        parent.layer.close(index);
                    });
                } else {
                    layer.alert(data.msg, {icon: 6}, function () {
                        // 获得frame索引
                        var index = parent.layer.getFrameIndex(window.name);
                        //关闭当前frame
                        parent.layer.close(index);
                    });
                }
            })

            return false;
        });
    });

修改操作

public function doEdit(){
		//获取提交的数据
		$data=Request::param();
		$new=new NewsModel();
		$res=$new->save([
			'title'=>$data['title'],
			'desc'=>$data['desc'],
			'content'=>$data['content'],
			'username'=>Session::get('username'),
			'time'=>time(),
		
		],['id'=>$data['id']]);
		if($res){
			return ['res'=>1,'msg'=>'修改成功'];
		}else{
			return ['res'=>0,'msg'=>'修改失败'];
		}
	}	

edit.html中的$.post(url,data,function(data){})

          //监听提交
          form.on('submit(add)', function(data){
            console.log(data);
            //发异步，把数据提交给php
            $.post('{:url(\'doEdit\')}',{
            	'title':$('#title').val(),
            	'id':$('#id').val(),
            	'desc':$('#desc').val(),
            	'content':editor.txt.html(),
            	
            },function(data){
            	if(data.msg==1){
            		 layer.alert(data.msg, {icon: 6},function () {
                // 获得frame索引
               		 var index = parent.layer.getFrameIndex(window.name);
                //关闭当前frame
                		parent.layer.close(index);
            });
            	}else{
					 layer.alert(data.msg, {icon: 6},function () {
                // 获得frame索引
               		 var index = parent.layer.getFrameIndex(window.name);
                //关闭当前frame
                		parent.layer.close(index);
            });            		
            	}
            })
           
            return false;
          });

删除操作

public function del(){
		$newId=Request::param('id');
		$new=new NewsModel();
		if($new->destroy($newId)){
			return ['res'=>1,'msg'=>'删除成功'];
		}else{
			return ['res'=>0,'msg'=>'删除失败'];
		}
	}	

      function member_del(obj,id){
          layer.confirm('确认要删除吗？',function(index){
              //发异步删除数据
              $.get('{:url(\'del\')}','id='+id,function(data){
              	if(data.res==1){
					              $(obj).parents("tr").remove();
					              layer.msg(data.msg,{icon:1,time:1000});
					             }
             				 })
					          });              		
              	}

展示操作

	public function index(){
		$news=new NewsModel();
		$new=$news->order('id','desc')->paginate(8);
		$this->assign('new',$new);
		return $this->fetch();
	}	

	{volist name="new" id="news"}
          <tr>
     
            <td>{$news.id}</td>
            <td>{$news.title}</td>
            <td><img src="#"></td>
            <td>{$news.desc}</td>
            <td>{$news.username}</td>
            <td>{$news.time|date="Y-m-d H:i:s"}</td>
           
            <td class="td-manage">
              <a title="查看"  onclick="x_admin_show('编辑','{:url(\'News/edit\')}?id={$news.id}')" href="javascript:;">
                <i class="layui-icon">&#xe63c;</i>
              </a>
              <a title="删除" onclick="member_del(this,'{$news.id}')" href="javascript:;">
                <i class="layui-icon">&#xe640;</i>
              </a>
            </td>
          </tr>
          {/volist}
