I have something like this...

["a","b","c"]

I got it from PHP array using json_decode(). I'm very weak in JavaScript, but I need to get array in Javascript, so I can use it with jQuery UI -> Autocomplete like this...

source: [ 'a', 'b', 'c' ]

Is it possible to do with only Javascript or you need to have some Javascript library to use JSON?

Consider: <script>var myObj = <?= encode_your_php_object_to_json(...) ?>;</script> and what it implies. See json.org for more details. –  user166390 Jan 2 '11 at 7:15

Check out jQuery.parseJSON function.

Hey, You can do it only with javascript:

var arrayToUse = ["a","b","c"];

JSON stands for Javascript Object Notation and it is a standard notation for javascript objects. You do not need any special library to use it. Example,

If you want to create an object in javascript you would do something like:

var person = {
 name : 'somename',
source : arrayToUse
};

This is a javascript object in JSON notation

"JSON stands for Javascript Object Notation and it is a standard notation for javascript objects." That's a bit misleading. The standard notation for JavaScript objects is JavaScript object liternal notation. JSON is a subset of object literal notation. –  T.J. Crowder Jan 2 '11 at 7:11

JSON is more restrictive than JavaScript -- it is a valid subset. For instance, all keys must be quoted to be valid JSON. The grammar "tracks" can be followed at json.org –  user166390 Jan 2 '11 at 7:12
