Integrate script with Wordpress 'submit button'?

I was told this was possible, but not sure how -

I want to integrate a simple popup script into the 'submit comment' button on a wordpress site. So that, after the person clicks 'submit comment', the popup box pops up...can anyone tell me how to do this?

where should I be placing the script code?

 

Find the submit button code (maybe it is in the comments.php file of the theme directory) then add attribute for example: onclick="window.open(...)".

More about this function you can find here: http://www.javascript-coder.com/window-popup/javascript-window-open.phtml

 

thanks, would I add this before or after the submit button (if in comments.php). Does it matter?

 

You have to add it like this:

<input name="submit" type="submit" id="submit" tabindex="5" value="Submit Comment" onclick="window.open(...)"/>
