action的一个方法（就是这个方法不能过的参数menuId）我的类是继承了actionsupport的：
public String updateMenu() {
HttpServletRequest req = ServletActionContext.getRequest();
System.out.println("-----------");
String menuId = req.getParameter("menuId");
System.out.println(menuId);
try {
PrintWriter pw = response.getWriter();
pw.print("error");
} catch (Exception e) {
e.printStackTrace();
}
return "success";
}

页面js：
<script type="text/javascript">
function updateAction(menuId) {
document.menuListForm.action="${pageContext.request.contextPath}/updateMenu.do?menuId="+menuId;
document.menuListForm.submit();
}
</script>

通过这个js方法，我实在不知道为什么action中的那个方法获取不到menuId

打印的定西就是这个：
-----------
null
null

另外，我点浏览器刷新图标后页面会有乱码，网上说跟tile有关系

你先确定是否进入那个action的那个方法里面没有.如果没有自己找错误。。。 然后再检查一下页面的name属性和get参数名称是否一样，都用struts了，为啥还用request这个方法...

我知道了！！！！哈哈哈，因为我之前一直用的struts1，在struts1的项目里经常这样写，在struts2里直接用input name直接对应action的属性了，这就是struts1 跟struts2的区别呀！！！
