Short #jQuery chunk which assigns an #onClick #function to each #pageBlockTable #row which finds the #checkbox in the row and simulates the onClick event on the checkbox. Ignores clicks on the checkbox itself, and ignores clicks on links

rowCheckBox.js

//dataRow is the class that Salesforce applies to all data rows, but you could equally use this in a non Salesforce context
$(".dataRow").click(function(event)
{
	//Ignore link and checkbox clicks, otherwise find the row's checkbox and click it
	if(event.target.type!=="checkbox" && !$(event.target).is('a')) {
		$(this).find($("input:checkbox")).click();
	}
});
