What is the Difference between onclick and href="[removed]function name?

Question

Is there any difference between

1 : Link1

and

2 : 

        

Answer 1

The onclick version allows you pass 'this' as an argument, so you can refer back to the tag/object the click came from. Not possible with the protocol method:

yo yo yo

will spit out an alert popup with "yo yo yo", whereas

yo yo yo

will spit out 'undefined'.
