我正在尝试使用Themeroller小部件构建一个页面，我遇到了一些错误，无法弄清楚原因。第一个：我的拖动元素一直在我的drop元素后面，而不是在它上面。第二个：我的标签不显示为标签，而是一个无序列表（这个不一定是一个bug，我只是对jQuery UI很新，我很难链接自定义主题和主题CDN，如果有人能解释我做错了什么，我将不胜感激。最后一个：我正在尝试使用datepicker（）（当然现在没有主题）让用户输入他们的生日。我希望他们按下然后收到通知，只是将他们的生日吐回来，我似乎无法用（$ datepicker）.value做到这一点。这是我的代码：

编辑：哎呀。好吧，我的主题正在运作。使用type =“stylesheet”而不是rel =“stylesheet” 编辑2：我创建了第二页，其中拖放代码几乎相同，并且拖动元素遍历drop元素。所以我的页面中的其他内容必定会导致它，但我不知道是什么。这是新文档中的拖放代码。
$(function(){
var drag = $('#dragdiv');
var drop =$('#dropdiv');
drag.draggable();
drop.droppable({
drop: function(){
drag.text('Dropped!');},
out: function(){
drag.text('No! Please! Take me back!');},
over: function(){
drag.text('Please drop me! Pls...');
}
});
});
几乎相同。事实上，我将此代码复制并粘贴到我的原始文档中，并仍然将拖动元素放在原始文件中的drop元素后面。有些东西告诉我我的CSS不能很好地使用我的代码。
答案 0 :(得分：0)
做到了。但是无法弄明白如何使用datepicker值。
