当我单击将鼠标悬停在文本上时出现的图像时，该元素将移动到另一个UL。我需要与第一个列表相同的图像选项才能将其删除。我不知道如何动态添加它。有人可以帮忙吗？提前致谢。

$(".list1").click(function() {
                var text = $(this).closest("li").text();
                $('<li/>', {html: text}).addClass("ui-selectee").appendTo('ul.seclist').append("<img src='cancel.jpg' class = 'list2 ui-selectee'/>");
                this.style.visibility = 'hidden';
            });

            $('ul').on('click', '.list2', function(e) {
                $(this).parent('li').remove();

                var liTwo = $(this).closest("li").text();
                var listItems = $("#firstlist li");

                listItems.each(function(li) {
                    var liOne = $(this).text();
                    if(liTwo.match(liOne)){
