JavaScript Array Push key value

Question

Ok, I\'m going a little wrong here and I\'ve already wasted an hour with this so hopefully one of you guys can help me.

var a = [\'left\',\'top\'],
    x = [         


        

Answer 1

You have to use bracket notation:

var obj = {};
obj[a[i]] = 0;
x.push(obj);

The result will be:

x = [{left: 0}, {top: 0}];

Maybe instead of an array of objects, you just want one object with two properties:

var x = {};

and

x[a[i]] = 0;

This will result in x = {left: 0, top: 0}.
