Parsing JSON Multiple Levels With JavaScript

Question

Hello currently I am trying to get a specific value, but not entirely sure how.

Below is part of the JSON data that i am using. the data is set to equal to "entries"

 var entries = "credits": {
    "crew": [
        {
            "id": 7469,
            "name": "JimUhls",
            "department": "Writing",
            "job": "Author",
            "profile_path": null
        },
        {
            "id": 7474,
            "name": "RossGraysonBell",
            "department": "Production",
            "job": "Producer",
            "profile_path": null
        },
        {
            "id": 7475,
            "name": "CeánChaffin",
            "department": "Production",
            "job": "Producer",
            "profile_path": null
        },
        {
            "id": 1254,
            "name": "ArtLinson",
            "department": "Production",
            "job": "Producer",
            "profile_path": "/dEtVivCXxQBtIzmJcUNupT1AB4H.jpg"
        },
        {
            "id": 7477,
            "name": "JohnKing",
            "department": "Sound",
            "job": "OriginalMusicComposer",
            "profile_path": null
        },
        {
            "id": 7478,
            "name": "MichaelSimpson",
            "department": "Sound",
            "job": "OriginalMusicComposer",
            "profile_path": null
        },
        {
            "id": 7479,
            "name": "JeffCronenweth",
            "department": "Camera",
            "job": "DirectorofPhotography",
            "profile_path": null
        },
        {
            "id": 7480,
            "name": "JamesHaygood",
            "department": "Editing",
            "job": "Editor",
            "profile_path": null
        },
        {
            "id": 7481,
            "name": "LarayMayfield",
            "department": "Production",
            "job": "Casting",
            "profile_path": null
        },
        {
            "id": 1303,
            "name": "AlexMcDowell",
            "department": "Art",
            "job": "ProductionDesign",
            "profile_path": null
        },
        {
            "id": 7763,
            "name": "RenKlyce",
            "department": "Sound",
            "job": "SoundEditor",
            "profile_path": null
        },
        {
            "id": 7764,
            "name": "RichardHymns",
            "department": "Sound",
            "job": "SoundEditor",
            "profile_path": null
        },
        {
            "id": 7467,
            "name": "DavidFincher",
            "department": "Directing",
            "job": "Director",
            "profile_path": "/dcBHejOsKvzVZVozWJAPzYthb8X.jpg"
        },
        {
            "id": 7468,
            "name": "ChuckPalahniuk",
            "department": "Writing",
            "job": "Novel",
            "profile_path": "/8nOJDJ6SqwV2h7PjdLBDTvIxXvx.jpg"
        }
    ]
}
}

I then parse through the data using this:

crew_member = 0,
crew_members = [];

for (crew_member = 0; crew_member < entries.credits.crew.length; crew_member++) {
    crew_members.push(entries.credits.crew[crew_member].job + ': ' + entries.credits.crew[crew_member].name);
}

document.getElementById('Crew').innerHTML = crew_members.join(',');

Everything works on my end. The problem I am having is how to specifically get for example the director and the director only.

Answer 1

It's a simple if statement:

for (crew_member = 0; crew_member < entries.credits.crew.length; crew_member++) {
    if (entries.credits.crew[crew_member].job == "Director") {
        crew_members.push(entries.credits.crew[crew_member].job + ': ' + entries.credits.crew[crew_member].name);
    }
}
