javascript - Getting keys of an object that has same values -

i have object like:

 object {v: 1, b: 1, n: 1, m: 1, c: 2, d: 3} 

i trying collect keys has same values , generate array (so in case [v, b, n, m].

so if know 1, how can v,b,n,m in array?

you can use object.keys() key values of object, filter values based on condition using filter()

var obj = {      v: 1,      b: 1,      n: 1,      m: 1,      c: 2,      d: 3    },    val = 1;    var res = object.keys(obj).filter(function(v) {    return obj[v] == val;  });    document.write('<pre>' + json.stringify(res, null, 4) + '</pre>');
