Question

How can you check whether the element is the original element or a propagation of the clicked element?

---

Edit

If I do this, 'propagation' is always alerted:

this.row.click(function(e){
    if(e.target === this) alert('origin');
    else alert('propagation');

    //e.stopPropagation();
});

Check event.target ^[docs]:

if(event.target === this) {
    // origin of the event
}
