Intercept click event on a button, ask for confirmation, then proceed

Question

Based on a variable SomeCondition, I need to intercept a click event on a button, and ask for confirmation, if they say ok, proceed, otherwise ignore click.

Answer 1

I could not get any of the answers above to work using jquery 1.9.1

here is what worked for a previously set click event

var elem = $('#button1');
var oldClick = $._data(elem[0], 'events').click[0].handler;
elem.off('click');

// Pass the original event object.
elem.click(function(e){
  if(window.confirm("Are You Sure?")){
    oldClick(e);
  } else {
    return false;
  }
});   

very similar to Jason Benson's answer above
