jquery - manually call a function in javascript?

Question

How do you do this? like PHP has call_user_func

I'm trying to pass a callback function to jQuery.animate(), like this

...
complete: function(){ 
  // do_something 
  call_function(my_callback); // here need to call my_callback
}
...

Answer 1

You can simply call it like you would any function

 my_callback();

JavaScript also has a call method that some people prefer

 my_callback.call();

Here's a link I found with some extra information regarding the call method. https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Function/Call
