Question

我在liferay中使用我的自定义portlet。但不知何故，当我运行我的portlet时，我在错误控制台中有以下错误

Timestamp: 12/10/2012 12:33:19 PM
Error: ReferenceError: AUI is not defined

Error: ReferenceError: Liferay is not defined
Source File: http://localhost:8080/eMenuAdvertise-portlet/js/jquery.min.js
Line: 3

那么为什么这个错误会出现在我的jsp页面中的一些jquery？

Answer 1

在<script>中，您有两个javascript函数 - createRowURL和createRenderURL，它们使用Alloy UI脚本，如下所示：

function createRowURL( row ) {
   var portletURL = new Liferay.PortletURL(); // this is the line using AUI
   portletURL.setParameter("rowNumber", row );

   return portletURL.toString();
}

function createRenderURL(str) {

    alert("");

    var renderURL = Liferay.PortletURL.createRenderURL(); // this is the line using AUI
    alert("hi");
    renderURL .setParameter("jspPage",str);
    renderURL .setPortletId("eMenuAdvertise_WAR_eMenuAdvertiseportlet");
    // i.e. your-unique-portlet-id can be like "helloworld_WAR_helloworldportlet"
}

因此，我建议您使用此<script> ... </script>标在你的jsp中定义taglib，如：

<aui:script> ... </aui:script>

修改（在看到主题模板后）：

我可以看到，在AUI您已分别从Liferay和<%@ taglib uri="http://alloy.liferay.com/tld/aui" prefix="aui" %>`标记中删除了以下行：

portal_normal.vm

请在主题模板中包含这些语句，您的脚本才有效。语句<head>这有责任包括所有<body>相关内容（javascripts，函数等）以及请求属性中的一些变量。

注意：从主题和挂钩中删除任何内容时请务必小心。您应该始终知道要删除或修改的语句的目的是什么。

希望这有帮助。

AUI没有定义，Liferay在jsp页面中没有定义错误？
