simple javascript variable in function

Copy linkTweet thisAlerts:

function select(exID)
{
document.inputform.select.value=exID;
show(‘select_’.exID.”);
}

Here is my simple function. On line 3, I’m trying to pass a variable along with a little text into the function, but I’m having little luck. In PHP, I would accomplish this by saying:

show(‘select_’.$exID.”);

For some reason, this isn’t working (probably because I know crap about JS). Halp?

show('select_'.exID.'');
[/code]
This is not a syntax I recognize:

Try this:
[code=php]
alert('exID = '+exID);
[/code]
or
[code=php]
alert(document.getElementById('exID').value);
[/code]
to see what's going on.

Might also want to post a little more of the calling HTML code

to see how the element 'select_???' has been defined.

If it's a select box, you will need to reference differently.
[code=php]
var obj = document.getElementById('exID');
alert('Show: '+obj.option[obj.selectedIndex].value)
[/code]
