Join JSON Object member string values together

category: [{

      id: 28,

      name: Dogs

  },

  {

      id: 14,

      name: Cats

  },

  {

      id: 878,

      name: Sheep

  }],

I have the above JSON parsed (using .ajax and jsonp as callback) and I would like to join all the values of name into a string. i.e. Dogs, Cats, Sheep. How can I do this? I have tried simple join on category and name, i.e.

var cats = categories.join(, );

OR

var cats = categories.name.join(, );

But since we are looking at it's members and their string values, it doesn't work.

This looks like a job for $.map!

var data = {

    category: [{

          id: 28,

          name: Dogs

      },

      {

          id: 14,

          name: Cats

      },

      {

          id: 878,

          name: Sheep

      }]

}



var cats = $.map(data.category, function(v){

    return v.name;

}).join(', ');
