Hi jQuerians,
I'm wondering what is the best way to concatenate (callback) functions.
The problem: I call a certain function several times passing in a
function reference that is used as a callback. All callbacks will be
used in one large callback in the end but I cannot build the callback at
once.
initialize(funcRef);
...
initialize(anotherFuncRef);
function initialize(callback) {
// concatenate callbacks from different calls
}
What would be the most elegant way to do this? I had the idea to store
the functions in a list and call them one after the other in a loop.
The other idea I had is this:
var myCallback;
function initialize(callback) {
if (myCallback) {
myCallback = function() {
myCallback();
callback();
}
} else {
myCallback = callback;
}
}
Hm, that doesn't convince me either. Both ideas make me think there is a
more elegant way to achieve this. Is there a better pattern from the
gurus out there?
Thanks!
