JAVASCRIPT: Redirect

I keep having to look this one up, so I posted it here so I could always find it.

<button 
onclick="window.location='http://www.mysite.com/';">

this also works:

<button 
onclick= "window.location.href='http://www.mysite.com/';">

HTML: No dotted line on links

In order to get rid of this dotted lines on links, you write code so link says 'when you click on my and therefore focus the cursor on me, then blur me'

<a href=http://www.google.com 
onFocus="if(this.blur)this.blur()">Google</a>
