capturing change event in the drop down

I need some help on this. Thanks in advance.

I have 4 pages, all 4 pages have drop down, text, radio....

In page1 drop down, if the value is changed and go the next step without
saving, I need to give a popup message saying,
"You have made changes to this page. Clicking OK will disregard your changes. Do you wish to continue without saving?"

But I am getting the popup even if there is no change.

Here's the code:

case "select-multiple" :

for (var x = 0, y = ele[i].options.length; x < y; x++) {

if ( ele[i].options[ x ].selected != ele[i].options[ x ].defaultSelected ) return true;

}

break;

Did you check to see what actual values are getting compared? Are they what you expect?

Bear,

I am not good at JavaScript, if I need to print those two values, do I need to use document.write()?. I tried giving that it doesn't print. Can I print to the standard output? Thanks a lot.

If you're going to be writing JavaScript, you need to learn a bit about how to debug your code.

I highly recommend Firebug for Firefox. With it, you can write to the Firebug "console" using:



Very useful during debugging!

Failing that, using good old alerts is better than nothing.

And no, you can't use document.write once the page has finished loading.
