传多个id 存入一个容器里，让另一个页面接受并显示数据

Posted 2020-09-19 遇事稳坐钓鱼台

要传页面的id：

　　<ul class="contrast-ul">
　　
<!-- <li>id都在这里面</li> -->
    </ul>
  
    </div>
    <div class="contrast-act clearfix"> <a href="javascript:;" target="_self" class="go-contrasts fl">开始对比</a> <a href="javascript:;" class="go-reset fr">清空</a> </div>
    <script>
     $(\'.go-contrasts\').click(function(){
         var dbli = $(\'.contrast-ul\').find(\'li\');//收集所有<li>里面的 id
        var t_Str = \'\';
        $.each(dbli,function(index,ele){
            t_Str = t_Str + \'_\' + $(ele).attr("data-platid");  //以 _ 分隔
        })
        t_Str=t_Str.substr(1,t_Str.length-1);
         var url = "{:U(\'Index/data_duibi\')}" + \'/data/\' + t_Str;
        location.href = url;
     });
      
        //30_29_29 join
    </script>

data_duibi页面 的控制器里方法

    public function data_duibi(){
        $data = explode(\'_\', I(\'get.data\'));
        $grade = $this->grade_model->where(array(\'id\'=>array(\'in\',$data)))->select();
        $this->assign(\'grade\',$grade);
        
        foreach($grade as $k=>$r){
            $tmp = $this->archives_model->where(array(\'delete\'=>0,\'id\'=>$r[\'aid\']))->find();
            $archives[] = $grade[$k][\'archives\'] = $tmp;
            
        }
        $this->assign(\'archives\',$archives);
        $this->display(":data_duibi");
    }
