Hi,

I'm puzzled by the following or more likely I don't know better.

I have this form with a select element and then I want to see what is selected on the same page, code is like this:

<select id="me">
<option>apple
<option>orange
...
</select>

<span id="findme"></span>

js after user has selected the above:

if (document.getElementById('me')) {
var ee = document.getElementById('me');
var eev = ee.options[ee.selectedIndex].value;
document.getElementById('findme').innerHTML = eev;
}
else {alert('WHY me field NOT FOUND');}

I expect to see the span id to display the value of the selected option
but I get the alert instead, what's wrong?

Thanks.

Luuk

try:

<!DOCTYPE html>
<html>
<head>
<script language="javascript" type="text/javascript">
function xme() {

if (document.getElementById('me')) {
var ee = document.getElementById('me');
var eev = ee.options[ee.selectedIndex].value;
document.getElementById('findme').innerHTML = eev;
}
else {alert('WHY me field NOT FOUND');}
}

</script>
</head>
<body>
<select id="me" onchange="javascript:xme();">
<option value="Apple">apple
<option value="Orange">orange

...
</select>

<span id="findme"></span>

</body>
</html>

When I looked deeply I noticed the id attribute was REMOVED! of course it couldn't be found. This FORM has los of elements, each has an id (it's been like that for a while...)
Some criminal is really EVIL... (hacked my computer and probably is being paid for doing that...)
