Question

I googled but most of them is to bind different event for SAME element.

For

$('#a').change(function() {
     /bla
     /bla
});

$('#b').click(function(){
     /bla
     /bla
});

I want something like this

$('#a').change OR ('#b').click(function(){
     /bla
     /bla
});

Answer 1

Try this:

var func = function(){
     /bla
     /bla
};

$('#a').change(func);
$('#b').click(func);
