I'm trying to add an onchange event to dropdowns.
All dropdowns have the same class attached.
I created an addInitEvent call to a function that calls an addEvent
for all found dropdowns with that class:
function linkToPage(obj) {
//for testing only
alert(obj.value);
}
The addinitevent calls this function to assign the event to each select tag:
function installDDs() {
// Find all select with class 'url' and enable them
if (!document.getElementsByTagName) return;
var popups = document.getElementsByTagName("select");
for (i=0;i<popups.length;i++) {
var thisPopup = popups[i];
if ((' '+thisPopup.className+' ').indexOf("url") != -1) {
addEvent(thisPopup, 'change', function(){linkToPage(thisPopup)});
//test if a popup was found
alert('initialize '+thisPopup);
}
}
}
addInitEvent(function(){installDDs();});
When the page initially loads, I get the 'initialize...' message
indicating that it found an appropriate object.
But when I change the dropdown nothing happens, not even a javascript
error. I looked through
http://wiki.splitbrain.org/wiki:devel:javascript and the code to look
for any clues.
Am I useing addEvent wrong? I modeled if after the footnote javascript.
Am I passing the object itself into the event wrong?
Any pointer would be greatly appreciated.
TIA...martin
