JSP（四行代码）

<%@ taglib prefix="s" uri="/struts-tags"%>
<html>
    <head>
        <s:head theme="ajax" debug="true"/>
        <script type="text/javascript">

Answer 1

好吧，因为Ajax主题是使用DOJO处理的，你需要在JSP中包含它。第一步是在jsp中添加Struts-dojo标记库，方法是添加以下行

<%@ taglib prefix="sx" uri="/struts-dojo-tags"%>

嵌套步骤是通过要求S2加载所需的文件和其他东西以使Ajax主题正常工作来启用Ajax支持。继续跟踪你的index.jsp

<sx:head />

如果您使用的是S2 2.1及更高版本，我不建议使用DOJO标签，因为该插件已被弃用，而是使用简单的DOJO / Jquery或者已经有一个用于S2的Jquery插件
