Answer 1

我想错的是这行把<a href="javascript:doSubmit('${pageContext.request.contextPath}/accreditor.do?menu=modifyPage&id=<%=id%>')"><img src="file:///D|/My Documents/未命名站点 1/print.jpg"></a>

Answer 2

看你报错的第一句话应该是没有找到对应的参数，参数名是“menu”，后面给你的原因因该是这个组件有可能是一个lable而不是一个input。

Answer 3

改成下面的看看<a href="javascript:doSubmit('${pageContext.request.contextPath}/accreditor.do?menu=modifyPage&id='+<%=groupcode%>)"></a>

Answer 4

.....groupcode是我测试的时候随便写的。你改成你的id就好了。你试试看，只是猜测问题可能出在哪。
