On click Confirm popup (Jquery)

// Info: Attach event to all elements with this data attribute 
// works even for elements that will be created afterwards by Ajax or Jquery
// Only thing you do is to put a data-popmsg attribute in the element you want to click and the value of this attribute
// will be the body of the popup.

$(document).on("click","*[data-popmsg]",function(e){
        var msg = $(this).attr("data-popmsg");
        if(!confirm(msg))
        {
        e.preventDefault();
        }

    });

Asterisk(*) is a bit expensive. If you have certain selectors use something more specific to gain some speed.
