Question

Can we put two JavaScript onclick events in one input type button tag? To call two different functions?

Answer 1

This one works:

<input type="button" value="test" onclick="alert('hey'); alert('ho');" />

And this one too:

function Hey()
{
    alert('hey');
}

function Ho()
{
    alert('ho');
}

.

<input type="button" value="test" onclick="Hey(); Ho();" />

So the answer is – yes you can 🙂
However, I’d recommend to use unobtrusive JavaScript.. mixing js with HTML is just nasty.
