Hi guys,
Warning! JS newbie coming through. I have a problem with attaching
onchange handlers to menu options. The full script I am referring to is
at http://www.firelightning.com/js/switcher.js and the specific function
is this:
/* FUNCTION: ATTACH ONCHANGE EVENT TO MENU */
function menuSetup() {
var styleMenu = document.getElementById('styleMenu');
// Attach an onchange event to each menu option:
for (var i=0; i < styleMenu.length; i++) {
styleMenu[i].onchange = setStyle(styleMenu[i].value);
}
}
Now, this function is called on page load and as far as I can tell this
should work by just telling the browser to listen for the onchange
event. What actually happens is that when the page loads, the event is
fired for each menu option in turn instead of waiting for user input. I
can't for the life of me work out why. I don't see what fundamental
difference there is between my script and the examples at
http://www.quirksmode.org/js/events/window.html on PPK's site.
I really hope someone can help. :)
Thanks,
Iain
