Question

I have a function like

function a (p1, p2) { /* ... */ } 

and in some scope want to get something like this:

function b (/* no params! */) { return a (my1, my2) } 

where my1 and my2 are defined somehow in this scope. So I should get a parameterless function b, which when called calls a with fixed parameters my1 and my2. Now, the question is, why this is not right, and which is 🙂

UPD: Ok, I had some callbacks in those params, now found out, how to process them all. What I missed was to apply the technique twice. Thank you.

Answer 1

Just make a function that returns a new function b:

function getB(my1, my2) {   return function() {     a(my1, my2);   } } 

and use it like this:

var b = getB(my1, my2);
