How to get the name of an object in an associative array (javascript)

Question

Lets suppose I have this object

var cliCorp14={
  "id":13,
  "url":"corp_longboard.html",
  "logo":"img/corp/logoLongboard.png",
  "alt":"Longboard store",
  "name":"LONGBOARD",
};

I want to put the text "alt" in a var. I don't want to put "Longboard store", I want to put the text "alt". How do I access to that object?

Answer 1

for(var x in cliCorp14)
{
console.log(x);
}

Answer 2

Object.keys(cliCorp14);
// -> ["id", "url", "logo", "alt", "name"]

Note that Object.keys() is an ES5+ method, and only available in IE9+ (although it is easy to polyfill).
