怎样用javascript提交strtus表单 在线等待
<form-bean   name= "userinfoForm "   type= "chojo.struts.form.UserinfoForm "   />

userinfo.jsp
<html:form     action   =   "userinfo.do "   focus   =   "userid "   method   =   "post ">
<td> <html:button   property= "button "   onclick   =   "JavaScript:delSubmit(this) "> delete </html:button> </td>
</html:form>
js
function   delSubmit(obj){
  document.userinfoForm.action   =   "/WebRoot/deluser.do ";
  document.userinfoForm.submit();
}
为什么   document.userinfoForm.submit();   报错，而不提交表单，求高手解决方法

------解决方案--------------------
document.userinfoForm.action = " <%=request.getContextPath()%> /WebRoot/deluser.do ";
document.userinfoForm.submit();
------解决方案--------------------
deluser.do和userinfo.do

在stucts-config.xml是怎么定义的
------解决方案--------------------
<html:form action = "userinfo.do " focus = "userid " method = "post " id= "uf ">
这里加一个id

js:
document.getElementById( "uf ").submit();

------解决方案--------------------
报什么错 ？？
