I thought this would be really simple, but i'm stumped. I'd like to validate some data without submitting the form, but i can't seem to get the focus to go back to the field with the bad data. I've stripped out most of the code just to illustrate the problem. In both IE and Mozilla, the focus still goes to the next element. This is .php generated.
<html><body><sc ript type="text/javascript">
var numAdults=5;
var numChildren=0;
function Check(element){
value=parseInt( element.value);
if(isNaN(value) || value<0 || value>99){
if(element.name =='txtNumAdults '){
element.value=n umAdults;
}else{
element.value=n umChildren;
}
element.focus() ;
return false;
}else{
//SetDirty(elemen t);
return true;
}
}
</script>
<form action="a1.php" method="POST" name="myFrm">
<table>
<tr><td align="right">< label>Adults:</label></td>

I've seen it before. It has something to do with the onChange. I don't
remember exactly, but the solution was to change onChange to onBlur,
since change isn't fired until a text element loses focus anyway. (I
tried that with your code and it worked.)
Beware: if a user hits enter to submit the form, the onBlur won't fire.
Double up the validation so that onSubmit also validates, JIC.

Kaeli,
Thanks. Using onBlur() fixes it for IE, but it still doesn't
work in Mozilla. What's also odd, is that if i add an
element.select( ); it will select the text, but the focus
still moves to the next element. Specs require that it works
in Mozilla also as many of the users have Linux workstations.
Any suggestions there?
Heh, i just found out that Mozilla had a new release yesterday
that is supposed to fix this. We shall see. Always nice to
know *I* wasn't doing anything wrong.

Good to know.
Unfortunately, my Unix users use NN7 and I haven't tested this in that
browser.
I ended up moving all my validation to onSubmit awhile ago when I had to
support that POS NN4.

I have web page that contains two links.
link "a" and link "b". When I click on "a" a small window should pop
up. when I click on "b" another small window should pop up. So what you
should see now is the base window which contains links "a" and "b" and
two small pop-up windows "a" and "b". Now I can make the script to pop
up "a" and "b" but the problem is that they're not shown at the same
time.
Any suggestions????
