【问题讨论】：

我们需要查看更多代码，特别是您在 AllyUI 脚本中加载的部分。
您是否已经将<script src="http://cdn.alloyui.com/3.0.1/aui/aui-min.js"></script> 放入您的HTML 中的脚本之前？

标签： javascript jquery alloy-ui

【解决方案1】：

您必须将<script src="http://cdn.alloyui.com/3.0.1/aui/aui-min.js"></script> 放在您呼叫YUI() 的<script> 之前。

【解决方案2】：

在运行自定义 JS 代码之前，您需要加载 aui-min.js 脚本。
