I have an input button that calls a window.location.href event, and also want to add google analytics event tracking to the same button...

How would I combine these two events into one statement?

```
<input type="button" value="Learn More!"  onclick="window.location.href='site1'" />

```

and this event:

```
onclick="_gaq.push(['_trackPageview', '/externalsite/site1']);"

```
