Question

I have this JSON data:

var people = [
     { name : "John",  age : 25 },
     { name : "Jane",  age : 49 },
     { name : "Jim",   age : 31 },
     { name : "Julie", age : 39 },
     { name : "Joe",   age : 19 },
     { name : "Jack",  age : 48 }
];

How can I loop through all the objects inside people and output their names along with their ages like so:

John 25
Jame 49
followed by the rest...

Answer 1

Use a for loop: http://www.w3schools.com/js/js_loop_for.asp

for (var i = 0; i < people.length; i++)
{
     document.write(people[i].name + ' ' + people[i].age + '<br />'); 
}

or the each function in jQuery: http://api.jquery.com/jQuery.each/

$.each(people, function(i, o) {
   document.write(o.name + ' ' + o.age + '<br />'); 
});
