Question

Given:

  { \"attr1\": \"bob\", \"attr2\": \"pizza\" },
  { \"attr1\": \"john\", \"attr2\": \"sushi\" },
  { \"attr1\": \"lar         


        

Answer 1

Using jQuery .each()

var peoples = [
  { "attr1": "bob", "attr2": "pizza" },
  { "attr1": "john", "attr2": "sushi" },
  { "attr1": "larry", "attr2": "hummus" }
];

$.each(peoples, function(index, obj) {
   $.each(obj, function(attr, value) {
      console.log( attr + ' == ' + value );
   });
});

Using for-loop:

var peoples = [
  { "attr1": "bob", "attr2": "pizza" },
  { "attr1": "john", "attr2": "sushi" },
  { "attr1": "larry", "attr2": "hummus" }
];

for (var i = 0; i < peoples.length; i++) {
  for (var key in peoples[i]) {
    console.log(key + ' == ' + peoples[i][key]);
  }
}
