As in if I have var x = "foo" and I need to create a new variable called foo by using x. Like var "valueOf(x)" = ... or something. I can't seem to figure it out.

    If I understand your questions, it seems to be a duplicate: http://stackoverflow.com/questions/5613834/convert-string-to-variable-name-in-javascript - hope this helps! – André Jun 17 '15 at 13:10
  • @Jackson — The question is asking how to use the value of a variable as the name of another variable, not how to give two variables the same value. – Quentin Jun 17 '15 at 13:10
  • What Im trying to accomplish is this: I have a variable that's is set to name and then another variable set to its value, I want to combine these two, the name with the value as in: var name = value – Ferus Jun 17 '15 at 13:14
  • @Ferus — Yes, that's what the duplicate question explains how to do. – Quentin Jun 17 '15 at 13:16
  • Alright, didn't see that post, thanks. – Ferus Jun 17 '15 at 13:21

Try this:

var x = "foo";
window[x] = 'hi';
alert(foo);

What scope are these variables in? If they are on the window (global context ) you can use the bracket notation call window[x] = bar and will now have a bar variable available. If it's in a function it would be more clear to use this instead of window

  • In that case use `this[x] = 'bar'` and now the local variable foo will be available in that function and equal to bar – PhilVarg Jun 17 '15 at 13:22
