How to parsing Json Array in Javascript?

Json Array as following is easy to parse,

{
    "movieCategories": [
       "a" : "Animation",
         "b" :"Romance",
        "c" :"Science Fiction"
       "d" : "Western"
    ]
}

Now,I have a Json response as following which is stored in movies.json file.

{
    "movieCategories": [
        "Animation",
         "Romance",
        "Science Fiction",
        "Western"
    ]
}

I am not sure how to parse the above json array. Kindly help.

Thank you.

you can only use the eval like

<html>
<div>
<script language="javascript">
  var arr = '[{ "movieCategories": [ "Animation", "Romance", "Science Fiction" ,"Western" ] }]';
  var b = eval(arr)[0];
  alert(b.movieCategories);
</script>
</div>
</html>

Download json2.js from here https://github.com/douglascrockford/JSON-js Include it on your page. Use like this

jsonobj = JSON.parse(jsonstring);
jsonstring = JSON.stringify(jsonobj);

Assume 

    var test = {
    "movieCategories": [
        "Animation",
         "Romance",
        "Science Fiction"
        "Western"
    ]
}

then 

test.movieCategories[0] // Will be Animation

According to JSLint this is invalid JSON. There is a "," missing:

{ "movieCategories": [ "Animation", "Romance", "Science Fiction", "Western" ] }

For the rest see: Is it possible to parse JSON with javascript?
