Question

I have:

var array = [ { key: '1' }, { key: '2' }, { key: '3' } ]

I want:

var obj = getFirstItem(array, 'key', '2');

And as a result:

obj = { key: '2' }

Is there such function in JavsScript or jQuery?

Answer 1

I don’t know of a built in function. However, it would be trivial to implement it yourself:

var data = [ { key: '1' }, { key: '2' }, { key: '3' } ];

function getFirstItem(input, key, value) {
    for(var i = 0; i < input.length; i++) {
        if(input[i][key] === value)
            return input[i];
    }
}

console.log(getFirstItem(data, "key", 2));
