Question

如何在js中，把带参数的url 复制给struts form中的action

代码如下：
var url = "<%=request.getContextPath()%>/cmdparam.do?op=modifyinfosave";
url +="¶m="+ <%=request.getParameter("param")%>;
document.cmdparamForm.action.value = url;
alert(document.cmdparamForm.action.value);
document.cmdparamForm.submit();

显示 document.cmdparamForm.action.value 为 undefinded 无法为action赋值，这句该怎么改啊？？

Answer 1

把value去掉

document.cmdparamForm.action = url;
alert(document.cmdparamForm.action);
document.cmdparamForm.submit();
