Merge keys array and values array into an object in JavaScript

rated 0 times [ 67] [ 6] / answers: 1 / hits: 46361 / 15 Years ago, mon, july 13, 2009, 12:00:00

I have:

var keys = [ height, width ];

var values = [ 12px, 24px ];

And I'd like to convert it into this object:

{ height: 12px, width: 24px }

In Python, there's the simple idiom dict(zip(keys,values)). Is there something similar in jQuery or plain JavaScript, or do I have to do this the long way?

Simple JS function would be:

function toObject(names, values) {

    var result = {};

    for (var i = 0; i < names.length; i++)

         result[names[i]] = values[i];

    return result;

}

Of course you could also actually implement functions like zip, etc as JS supports higher order types which make these functional-language-isms easy :D
