Calling a callback in javascript

rated 0 times [ 149] [ 7] / answers: 1 / hits: 15393 / 14 Years ago, fri, october 1, 2010, 12:00:00

I am not so strong in javascript.

I have a common function that I call from many parts of my code passing them some parameters.

Can somebody help me on

how to define a new parameter for this function that should be a callback with no parameters passed from the caller (like many jquery plugins do)

how to handle the callback call inside the function

Giving advice regarding the solution, if there's a better one, etc.

thanks a lot!

It is actually quite simple.

function callback() {

    alert(I am in the callback!);

}



function work(func) {

    alert(I am calling the callback!);

    func(); 

}



work(callback);
