有无提交函数？

好象要这样写吧：
<body>
<form name = "form1">
<input type = "button" onclick = "doClick()">
</form>
</body>

可以这样写一个函数：
<html>
<script>
function submitForm(formName)
{
var obj = formName
var loc = "action.asp?"
with(obj)
{
for(i = 0; i < elements.length; i++)
    {
if(elements[i].value != "submit")
loc = loc + elements[i].id + "=" + elements[i].value + "&"
}
loc = loc.substr(0, loc.length-1)
alert(loc)
    window.location = loc
}
}
</script>
<body>
<img src="xbm.asp">
<form name="frm">
<input type="text" value="hello!" name="text1" ID="Text1">
<input type="text" value="hello!" name="text1" ID="Text2">
<input type="text" value="hello!" name="text1" ID="Text3">
<input type="button" value="submit" onclick="submitForm(frm)">
</form>
</body>
</html>action.asp为要提交到的页
<form id="form1">
<input type = "button" onclick = "document.all.form1.submit()">
</form>
要用id不能用name
