I can\'t find out what is the problem with this JSFiddle.
HTML:
Jav
The function is being defined inside a load handler and thus is in a different scope. As @ellisbben notes in the comments, you can fix this by explicitly defining it on the window
object. Better, yet, change it to apply the handler to the object unobtrusively: http://jsfiddle.net/pUeue/
$('input[type=button]').click( function() {
alert("test");
});
Note applying the handler this way, instead of inline, keeps your HTML clean. I'm using jQuery, but you could do it with or without a framework or using a different framework, if you like.
