sequential 'onclick' events

It it possible to have sequential onclick events such as:
<onclick>PlayMedia(address of a movie say),Playmedia(address of a music album say),...</onclick>
I tried just stacking them as a series of onclicks but it jumps from one to the other really quickly and does the last one
The reason I want to do this is that I want to be able to play the weather video then jump back to an m3u
