• IE: bubbling, to document
• Netscape: Capturing, starting from document
• Mozilla: Bubble + capture. To Window
• DOM: Bubbling + capture. Most compatible standard browser to window

Second, the Listener function

• Ie

  • There are two methods for each element and window object:

    [Object].attachevent (' onclick ', fnhandler); [Object].detachevent (' onclick ', fnhandler);

• Dom
  • syntax [Object].addeventlistener (' Click ', Fnhandler, false); [Object].removeeventlistener (' Click ', Fnhandler, false);
  • Load and release, must correspond to one by one for bubbling and capturing

Third, the event object

• Ie
  • is a property of window: window.event
• Dom
  • Pass the reference

Iv. Comparison of Event objects

• Default behavior for blocking events
  • IE Event.returnvalue = false;
  • DOM Ev.preventdefault ();
• Block event bubbling
  • IE event.cancelbubble = true;
  • Mozilla Ev.stoppropagation ();
• Mouse events
  • SOURCE Node
    • IE:event.srcElement
    • DOM:ev.target
  • MouseOver and Mouseout Event properties
    • Ie:fromelement, Toelement
      • Mouseover:toelement = srcelement
      • Mouseout:fromelement = srcelement
    • DOM:ev.relatedTarget
