Any ideas why I get duplicate alerts in IE, but not Netscape?

Hi

I am using the following function (called when a submit image is clicked on) to validate a form:

function validate() {
if (document.login.Cardnum.value =="&quot
{
alert("Please input your card number."
return;
}
else if (document.login.PIN.value =="&quot
{
alert("Please input your PIN number."
return;
}
document.login.submit();
}

in IE I get the alert boxes popping up twice, while in Netscape it works fine (i.e. only once) any suggestions?

Could you post a link to your page? I tried using it and it worked fine with the following form:

<form name=&quot;login&quot; action=&quot;#&quot; onsubmit=&quot;validate()&quot;>
<input name=&quot;PIN&quot;><input name=&quot;Cardnum&quot;>
<input type=&quot;submit&quot;>
</form>

So I'm not sure why you're havving a rpoblem with this. jared@aauser.com

Hi Jared

I really shouldn't post the page's address (company stuff under development), but keep in mind that I am calling it from an OnClick of an image (that may make some difference I guess).

Does that chagne how it works for you?

Just a thought ... does the submit method of the form also call the validate function? If so then you'll be calling the function twice ... fron onClick and submit. Not sure why the difference in IE & Netscape though :-|
