How to select a particular field from javascript array

Question

I have an array object in javascript. I would to select a particular field from all the rows of the object.

I have an object like

var sample = {
[Nam         


        

Answer 1

// assuming you mean:
var sample = [
    {Name:"a",Age:1},
    {Name:"b",Age:2},
    {Name:"c",Age:3}
]

Well, your biggest problem there is that no matter what happens, you'll have to loop. Now, jQuery will let you hide that behavior with:

var output = []
$.each( sample, function(i,e){ output.push( e.Name )} );

But fundamentally, that is the same thing as:

for( var i = 0; i < sample.length; i++ )
{
   output.push( v.Name )
}
