Description

The value of 'e.which' always returning '1' in the following events:

  • .mouseenter()
  • .mouseleave()
  • .mousemove()
  • .mouseout()
  • .mouseover()

But it works as expected on Google Chrome.

Here is a test case: http://jsfiddle.net/2c5kz/

There are multiple problems with the 'which' property. First off, the property has been labeled legacy by the w3c.

http://www.w3.org/TR/DOM-Level-3-Events/#legacy-key-attributes

The 'which' property has an issue with being a dual value property. Under certain circumstances the variable represents a keycode, other times it represents a mouse button index.

What you should be using is the 'buttons' property which is what the spec requires being set on a mousemove/mouseenter/etc/etc

Further more, webkit doesn't support 'buttons' yet, but firefox does. IE on the other hand doesn't support either. At this point, how do we determine which value is right, without putting in browser and version specific checks (because the browsers will be moving to support buttons eventually).

Here's a new fiddle

I agree, there's no reasonable way we can normalize or correct this across browsers at the moment. The browsers are lying about the buttons in different ways and there is no way to know when they are telling the truth.
