struts的提交参数传递及显示多条记录的问题, 谢谢!

问题一:
我的form都要提交的一个man.do但传递的参数不同.
如add时, action="/man.do?para=add"
delete时,action="/man.do?para=delete"
我用javacript不对呀.
<html:form name="form1" action="/man.do">
<input type=hidden name="para" value="" />
<input type="button" value="Add Task" onClick="onAdd()" />
<input type="button" value="Delete Task" onClick="onDelete()" />
</html:form>

<script language="javascript">
function onAdd(){
document.form[0].action="/man.do?para=add";
document.form[0].submit();
}
</script>

报错:avax.servlet.jsp.JspException: Must specify type attribute if name is specified.

这种情况该如何处理?

问题二:
如果页面显示多条记录如何做呀?是要form的数组嘛?越详细越好.

2,可以将记录集 put hashmap or ArrayList

<bean:define id="list" name="item" property="value" type="ArrayList"/>
定义arraylist
<bean:define id="item" name="beanId" property="hashmapInBean" type="ExpandHashMap"/>
定义一个hashmap
<bean:write name="item" property="value"/>输出
当然，要用到logic:iterate中

1.<script language="javascript">
var actionFlag = "";//action动作标志
function onAdd(){
actionFlag = "add";
document.form[0].action="/man.do?para=add";
document.form[0].submit();
}
function onDelete(){
actionFlag = "delete";
document.form[0].action="/man.do?para=add";
document.form[0].submit();
}
</script>
jsp中
<logic:equal name = "FormBean" property="actionFlag"value="add or delete">
</logic:equal>
