javascript - Checking length of dictionary object -

-

i'm trying check length here. tried count. there i'm missing?

var dnames = {};  dnames = getallnames();  (var = 0, l = dname.length; < l; i++)  {         alert("name: " + dname[i].name); }

dnames holds name/value pairs. know dnames has values in object it's still skipping on , when alert out dname.length that's not how this...so not sure. looked on web. not find on this.

what use object.keys() return list of keys , length of that

object.keys(dictionary).length
