When using third-party libraries such as jquery, yui-reset, swfobject and so on, do you link to the hosted versions, or download and host your own versions?
Pros and cons either way?
For example, for accessibility reasons I want my onfocus and onmouseover to have identical values. For the sake of maintainability I want to declare this once only.
What I'd like to be able to do is this:
<a onmouseover,onfocus="assist('hello');">linktext</a>
But, of course, that would be too easy, and doesn't work. What's the best way I can achieve this DRYing out of my tags?
