Validate a checkbox change??

[Slarti42]

I have a form to edit a field in a database. I want to display a confirmation dialouge if one checkbox is changed from the default value. ie if it's ticked when the load the page and they untick it I want the confirmation box to come up.

Thanks for any help

slarti? Is that you?

anyway, try this

<input type="checkbox" name="chngPass" value="True" onChange="javascript:alert('You changed the checkbox!!');'>

Will work with it being checked, or unchecked.

Thanks for the sugestion but it didn't seem to work. I'm generating the page from PHP, would that make any difference??

I display the checkbox like this:

echo("<tr>\n".
"<td align='right'>carotw &nbsp</td>\n".
"<td align='left'><input type=checkbox name='carotw' $carotw></td>\n"); 

where the $carotw is set to either "checked" or "".

Any other ideas??

Whoops, typing mistake, and I know this works, I tested it my self:

<input type="checkbox" name="testing" value="testing" onChange="javascript:alert('You hanged it');">

This line still dosen't seem to work???

I'm using IE5.5 SP2 is that the problem??

I tried just a simple form with just this checkbox on and still nothing. Do you need anything in the head or is this it??

Sorry to keep on, and thanks

Check it, then click anywhere else on the page.

I give up it still won't work for me!!!

Slarti, could you post the page online?

Thank you very much dhtlgod!!

I finally saw that a simple space between java and script was stoping it working. I changed it to "javascript" and it worked.

I've also looked at using "onClick" to bring up the alert.

From here I should be able to change it to a confirmation dialouge without too much trouble.

Thanks again for you help
