Question

Considering I have an array of objects, and all objects represent something out of a database, thus they have an unique identifier.

Now I also have the ID and the correct array. How do I search each object in that array where the parameter ‘id’ equals my ID. (The point is, I don’t know the internal identifier for that object. All I have is an ID and I need the entire object for description, last_user, created etc..)

Object
created: "2011-06-08 15:47:11"
description: "Something new.."
id: "1"
last_user: "1"

P.s. I have jQuery embedded, so if there’s no default way, a jQuery function would suffice.

$.grep() should do it. In the following example arr is your array of objects. It will find the element that has an id of 1.

var obj = jQuery.grep(arr, function(el, i){
  return el.id == 1;
})[0];
