我正在尝试在我的Web应用程序中使jQuery UI小部件工作 我从原始demo获得了所有文件，基本上我做了所有可能的事情，因此代码和文件几乎与演示版本相同。
并且一直都会收到此错误：未捕获TypeError：对象[object Object]没有方法'uniqueId'
这是js代码：
$(function () {
var date = new Date();
date.setDate(date.getDate() + 1);
$(".calendar", ".add-item").datepicker({
showAnim: "drop",
dateFormat: "yy-dd-mm",
minDate: date
});
$("#bar1").menubar({
position: {
within: $("#demo-frame").add(window).first()
}
});
$(".menubar-icons").menubar({
autoExpand: true,
menuIcon: true,
buttons: true,
position: {
within: $("#demo-frame").add(window).first()
}
});
$("#bar3").menubar({
position: {
within: $("#demo-frame").add(window).first()
},
items: ".menubarItem",
menuElement: ".menuElement"
});
});
以下是包含的文件：
<script src="@Url.Content("~/content/js/jquery-1.7.2.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/content/js/jquery-ui-1.8.21.custom.min.js")" type="text/javascript"></script>

删除包含：

答案 1 :(得分：3)
uniqueId是jQuery 1.9.x引入的新函数。我假设您使用jQuery 1.8.x的dev Widget（也就是GitHub的主分支）。
答案 2 :(得分：1)
在我看来，您还没有包含所有必需的源（.js）文件。该网址或您的网址错误。
从此页面中只包含一个UI包可能更容易： http://jqueryui.com/download/ 这样你知道你有所有必需的来源吗？
