Stop event propagation (stop an event from bubbling up)

Published in: JavaScript 

This is useful if I have an element that is inside a container, and I want to the element's event handler to fire without triggering the container's event handler. Then I would wrap the element's event handler function with this code.

See "PPK On JavaScript," pp. 315 and 323.

Plain TextExpand 
  1. function doSomething (e) {
  2.   var event = e || window.event;
  3.  
  4.   [body of event handler function goes here]
  5.  
  6.   if (event.stopPropagation) {
  7.     event.stopPropagation();
  8.   } else {
  9.     event.cancelBubble = true;
  10.   } 
  11. }
