How to parsing Json Array in Javascript?

Question

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.

If you didn't miss the comma after "Science Fiction" by accident, this is not valid JSON. — nfechner

You are missing a comma in your second example. Between "Science Fiction" and "Western". — Stefan

Your first example is invalid - you have labels inside square brackets. — N3dst4

@user515990: You should tell us how you are running things (we can't read your mind). You should also be sure you don't have tons of spelling and syntax errors on critical parts of your question — hugomg

Assume

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

then

test.movieCategories[0] // Will be Animation

Thanks,Gfox. Is it not necessary to have key associated with this? I mean, can I directly access it like test.movieCategories[0] ?

You're welcome.Yup if keys are not specified then it is considered as usual javascript Array and you can iterate through it as you do usually ;)

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);

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?

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>
