Question

In Javascript, if an object has lots of properties that are functions:

var obj = { foo: function() { ... },
            bar: function() { ... },
              ...
          }

then how can you get an array of names of those functions? That is, an array

["foo", "bar", ... ]

thanks.

Answer 1

var names = [];
for( var k in obj ) {
   if(obj.hasOwnProperty(k) && typeof obj[k] == 'function') {
      names.push(k);
   }
}
