Can you have call javascript only when print is called?

Question

I need to only use a piece of javascript when the print button is clicked, is there a way to do this?

EDIT: A browser print button, i was thinking something like this:

<script type="text/javascript" src="path" media="print"></script>

do you mean the browser print button? – Daniel A. White Oct 11 '11 at 12:48 — Daniel A. White, Oct 11 '11 at 12:48

There is only a partial support from browsers for that. Consider using special CSS stylesheet for print version of the page. For more details look at this question (there are links to several others): execute javascript when printing page

Some browsers (Firefox and IE) have events onBeforePrint onAfterPrint ...

Failing that use a "Press this to print" button and perform what you want from there ....

I think you mean this: JQuery:

$('#btnprint').click(function(){
     //Your JS code goes here
});

Watch out with postbacks!

Im not sure wether u mean the browsers print button or just a custom one, the code above is for your own custom one..
