jQuery store effect name in variable

Question

I'm searching for a couple of weeks to do this trick with jquery but everything failed so I'm posting it here.

Is it possible to store an effect name in a variable and then execute that effect on a div?
I mean something like this:

var effect = 'fadeOut';

$('#some_div').effect();

I hope you will understand what I'm searching for.

Answer 1

var effect = 'fadeOut';

var $div = $('#some_div');
$div[effect]();

Answer 2

Use brackets for the property access. Methods in JavaScript are properties too.

$('#some_div')[effect]();

Answer 3

Use bracket notation:

$('#some_div')[effect]();

This will run the function with the name equal to the value of effect.
