<form name="form1" method="post" action="xxxxxxxx.asp">
<input type="text" onpropertychange="if (this.value.length==8) this.form.submit();">
</form>

<script language="vbs">
<!--
function funcheck()
Dim ingc
Dim i
for ingc = 1 To len(Trim(document.all.T1.value))
If IsNumeric(Mid(Trim(document.all.T1.value),1)) Then
i = i +1
If i = 8 Then
form1.submit()
Exit For
End If
End If
End function
-->
</script>

<input name=T1 size=20 onpropertychange="funcheck()">

也可以用问号表达式：
<form name="form1" method="post" action="xxxxxxxx.asp" ID="Form1">
<input type="text" onkeyup="(this.value.length==8) ? form1.submit():1" ID="Text1" NAME="Text1">
</form>
