JavaScript在div后添加删除div

 var idd = \'str\';
        $(\'.task-done-detail-content-p7\').click(function () {
            var id = this.id;
            if(idd !== id){
                $(\'.do-task2\').remove();
                //选中的div后添加div
                $(this).after("<div class=\'do-task2\' ><p class=\'do-task-p2\'>修改任务</p><p class=\'do-task-p2\'>删除任务</p></div>");
                idd = id;
            }else{
                //去除添加div
                $(\'.do-task2\').remove();
                idd = \'str\'
            }
        });
