You can pass some parameter to a function used as callback in JavaScript.
These two options would look like this:
|
1 2 3 4 5 6 |
function firstfunction(callback) { // code here callback(arg1, arg2); } firstfunction(callbackfunction); |
Or
|
1 2 3 4 5 6 7 8 |
function firstfunction(callback) { // code here callback(); } firstfunction(function() { callbackfunction(arug1, arug2); }); |
