Get index of a key in json

Question

I have a json like so:

json = { \"key1\" : \"watevr1\", \"key2\" : \"watevr2\", \"key3\" : \"watevr3\" }

Now, I want to know the index of a key

Answer 1

You don't need a numerical index for an object key, but many others have told you that.

Here's the actual answer:

var json = { "key1" : "watevr1", "key2" : "watevr2", "key3" : "watevr3" };

console.log( getObjectKeyIndex(json, 'key2') ); 
// Returns int(1) (or null if the key doesn't exist)

function getObjectKeyIndex(obj, keyToFind) {
    var i = 0, key;

    for (key in obj) {
        if (key == keyToFind) {
            return i;
        }

        i++;
    }

    return null;
}

Though you're PROBABLY just searching for the same loop that I've used in this function, so you can go through the object:

for (var key in json) {
    console.log(key + ' is ' + json[key]);
}

Which will output

key1 is watevr1
key2 is watevr2
key3 is watevr3
