Tracking Clicks on iFrame Ads

iframe_click_tracking.js

// Limitations: 
// 1. We won't know where they are headed.
// 2. If the ads open in a new window, it doesn't trigger the unload event.
// 3. If there are multiple ad units in the iframe, we won't know which one was clicked.

function iframe_click_tracking(selector) {
	jQuery(selector).bind('mouseover', function() {		
		// If they are over the ad and click, the unload will trigger to log the click.
		jQuery(window).unload(function(){ // Event: onbeforeunload
			jQuery.ajax({url:'http://local.logger.com/logger/?log=mobile&message=realclick', async: false});
		});

		// If they leave the ad, then they aren't going to click. Kill the unload event.
		jQuery(this).mouseout(function(){ // Event: onmouseout
			jQuery(window).unbind('unload');
		});
		
		// So if the ads open in a new window and the unload isn't called, kill the unbind after a while. 
		setTimeout(function(){
			jQuery(window).unbind('unload');
		}, 2000);		
	});
