Question

I have a JSON object consisting of strings for the name and arrays for the value. Given a string within one of the arrays, how can I find the name it belongs to?

Example: Given the following JSON object, how can I use jQuery to get the answer “G1” when given the string “1” or “G2” when given the string “4”?

{
    "G1": [ "1" , "2" ],
    "G2": [ "3" , "4" ]
}

I’ve made a JSFiddle with my current work: http://jsfiddle.net/JmX6b/

Answer 1

var result;
for (var key in json) {
  if (json[key].indexOf(input) != -1) {
    result = key;
    break;
  }
}
