[解决办法]
<s:hidden name="apply" value="%{clApplyResource}" />
不要使用value
直接在Action里面直接set某某（apply值）；
<s:hidden name="apply" />便可
[解决办法]
<s:hidden name="apply" value="%{clApplyResource}" />
貌似要加styleId属性，比如 <s:hidden styleId="apply" name="apply" value="%{clApplyResource}" />
才能用document.getElementById("apply").value来获取值。。
html的<input type="hidden"/>也要定义id属性，才能用document.getElementById("apply").value获取
[解决办法]
哎哟妈呀，原来是要获取~~~
var id=document.getElementById("updateId").value;
不过我记得，用s:hidden标签，不能使用value属性
自己在Action set获取一下~~~
