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

That Javascript has no meaning. It is syntatically incorrect. I assume you meant:

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

Then you can use jQuery to do something like this:

var names = $(sample).map(function(){ return this.Name; });

But in reality all jQuery is doing is looping through the object for you. Writing your own loop would be (insignificantly) faster. There is no way to do this without a loop.
