Do not use document.all! It is IE-only.
Use document.getEle mentById instead, but you must give an id to your text box to use this.
To solve your problem, just add "return" before calling test().
it is not clear to me ........
plz explain in details .....
sorry i think i don't understand ur point of view ......
finally i managed to do that ....
here is my code .......
<input type = submit vlaue = "SUBMIT" onclick = "if(document.al l.txt.value == ''){alert('Blan k');return false;}">
it's lead me to new direciton of js event overriding ......
thanx , thanxxxxx a looootttttttttt ttttttttttttttt ttt............ ........

No, don't do that! I've modified your code below:
[HTML]<html>
<head>
<title>Simple Test</title>
<script language = javascript>
function test()
{
if(document.get ElementById("tx t").value == '')
{
alert('Blank');
return false;
}
else return true;
}
</script>
</head>
<body>
<form onsubmit = "return test();">
<input type=text name = txt id="txt">
<input type = submit value = "SUBMIT">
</form>
</body>
</html>
[/HTML]
is there any special difference between ur code and my code !!!!!!!!!!!!!!! !!!!!!!!!!!
i think it is easy to code ... nothing else ... am i right .........
lot of tahnx ......

No, document.all works in IE and is not standard (even though Opera supports it I think). document.getEle mentById is the standard and works in all modern browsers.
You could also use the name of the form to get access to the text input.
When you have onsubmit, why use the onclick for the submit? What if the form is submitted in some other way, e.g. using the submit() method?

Hi
Maybee a little bit of topic, but is it possible to stay on the
submitting page once you've clicked submit.
This is to get processing done on page B when you submit on page A,
and the page should not change. Normally I use a response.redirect to
the submitting page, but that can't be done in one case.

PS I've found that one solution is to send Response.Status = "204 No
Response"
but according to some information that won't work...
