I learned something on a project I was working on the other day. I was having trouble figuring out whether to use the which event or the button event when trying to detect what button was clicked in different browsers. Using the button event values returned inconsistent results. Using the which event value was more consistent but IE always returned it as undefined/null. Here is what I did to make it work for me.

$(#target").live("mouseup", function(event){
     if(event.which == null){
          // this is ie, left button is 1, right button is 2, middle button is 4
          if(event.button == 1){
               // left button clicked
               doSomething();
          }
     }else{
          //all other browsers, left which is 1, right which is 3, middle which is 2
          if(event.which == 1){
               // left button clicked
               doSomething();
          }
     }
});

Yes, that would let you synthesize when clicks may happen based on mouse movements and focus changes, but it's not detecting Adsense clicks. Ben calls out several places where it'll fail to do what you want, not to mention it doesn't tell you anything about the supposed click (e.g., the target), just that one probably happened.

How about this? http://www.bennadel.com/blog/1752-Tracking-Google-AdSense-Clicks-With-jQuery-And-ColdFusion.htm

@Resourcednet

No, you can't detect Adsense clicks; they're loaded in an IFRAME with a document from a different domain which is consequently inaccessible from your page's JS.

Is this script possible to detect Adsense click?

event.which is returning undefined in IE7…

The 'button' event attribute is not normalized by jQuery. But it does normalize event.which to be 1,2,3 depending on the button clicked (1=left,2=middle,3=right).

So use event.which instead of event.button.

nirvana,

If that's the case (I don't know, offhand), jQuery is isolating me (the developer) from it perfectly. Hit http://barneyb.com/r/jquery_live_button.cfm in whatever browser you want for a demo. FF and IE both return zeros for both live and click events.
