pass function into another function as parameter?

[soni2926]

hi,
is it possible to pass a function into another function as a
parameter? Say i have these:

function SaveMe(text)
{...}

function SaveMeNow(text)
{...}

function WhichToSave(x, y, z)
{...}

a button will call WhichToSave, that function will perform some logic
and then call one of the Save methods, can i pass that method in as
say parameter z and have it just call the function right away, passing
one of the SaveMe methods a parameter which is determined by the
WhichToSave method?

Thanks.

How does a button call something? Is WhichToSave a callback from an
event handler attached to a button, as in:-

button.onclick = WhichToSave;

?

Functions can be passed.

function invoker(f) {
f();
};

function a() {
document.title = "a";
}

invoker(a);

Yes.

function foo(){
alert('foo');
}

function bar(fn){
fn();
}

bar(foo); // alerts 'foo'

function reverse_str( s )
{ return s.split("").rev erse().join("")
}

function upcase( s )
{ return s.toUpperCase()
}

funcs = [reverse_str, upcase]
for (var i = 0; i<funcs.length ; i++)
document.write( "<p>" + funcs[i]( "was i able" ) )
