How can I call the same function 2 times in the same mouse action event?

<input type="submit" onMouseOver="myfunction(arg1,arg2)">

Here I wanna call the same javascript function 2 times.

I tried onMouseOver="myfunction(arg1,arg2)","myfunction(ar g3,arg4)" but it didnt seem to work.

Could I use onMouseOver="myfunction(arg1,arg2)" onMouseOver="myfunction(arg3,arg4)" ?

I hope someone know how to do this, otherwise I must make the function twice as big to do the operations I want.
