PHP-Like associative array initialization ?

[Remi Bastide]

Is is possible to initialize a javascript associative array inline, as
you would do in PHP, e.g. :

<?php
$a = array("abc" => "def", "ghi" => "jkl");
?>

Oops... forget about "associative arrays", as they sometimes cause
flaming discussion down here. Just call them objects (javascript
objects), and think of them as (imperfect) associative arrays.

As for the initialisation syntax, which is the javascript object
initialisation syntax ( see http://www.json.org ), you should be fine with :

a = { "abc": "def",
"ghi": "jkl" };

The quotes are optionnal, so the following is fine, too:

a= { abc: "def",
ghi: "jkl" }

However, if one of your keys has spaces or weird characters in it, se
the quotes:

cplx = { "abc d": "efg",
hij: "klm" };

Hope this helps,

Just what I needed, thanks.
