Hi ppl
I'm not very great on JavaScript, I spend most of my time in PHP, so
here's a really simple question for you.
I've a function that's intended to change the displayed price each
time someone chooses from various select options.
So I've got:
<script language='JavaScript'>
function changePrice(pOption)
{
// get what user selected
ind = document.giftOpts.pOption.selectedIndex;
val = document.giftOpts.pOption.options[ind].text;
window.alert ('Debug: Inside javascript: changePrice');
}
</script>";
I don't know how to make pOption, which is the name of the select tag
passed as a parameter into the function, be interpreted properly when
it's inside document.giftOptions.pOption.selectedIndex. I've tried
various combinations of getElementById and I've worked through all my
notes but it ain't happening.
Gimme a clue.
The select part goes like this:
<form method='post' action='index.php4' name='giftOpts'><select
name='abc' onChange='changePrice(abc)'>";
