key as variable when accessing javascript dictionary

Question

i am trying to store css values for transformations of multiple divs in a dictionary to access them when the div is clicked (the div id being the key of the dict).

my dictionary:

css_dict = {
    'keyA' : ['10px, 15px', '20px', '10px'],
    'keyB' : ['20px, 30px', '10px', '20px'],
    'keyA' : ['30px, 55px', '25px', '30px'],
}

i need to access it like this (variable instead of the key):

css_dict.var[0]

jsFiddle of what im trying to do: http://jsfiddle.net/tKFka/25/

i cant figure out or find the right syntax for this to work...

Answer 1

Use [] instead of dot.

var var1 = 'keyA';
css_dict[var1][0];
