 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‘
            }
        });
