JavaScript: Remove keys from json object - php

Question

Example output from PHP:
{
"RootName_0":{"Id":1,"ValId":1,"Value":"Colour","Text":"Blue"},
"RootName_1":{"Id":1,"ValId":2,"Value":"Colour","Text":"Red"}
}
How can I use Backbone.js or jQuery to only have:
[
{"Id":1,"ValId":1,"Value":"Colour","Text":"Blue"},
{"Id":1,"ValId":2,"Value":"Colour","Text":"Red"}
]
If it's easier to use PHP to edit the JSON, then so be it.

Answer 1

Well, in PHP it would be easy, just use array_values() on the initial array so that it 'forgets' the array indexes (which by the way, is what 'RootName_X' is called in your case:
$newvalue = array_values( (array)$value );
echo json_encode($newvalue);
In javascript, it's a bit trickier, but it would be on the lines of:
var newvalue = [];
for(var root in value)
newvalue.push(value[root]);
The question title is was a bit confusing since these are certainly not tags.

Answer 2

No need for jquery or Backbone:
var obj = {
"RootName_0":{"Id":1,"ValId":1,"Value":"Colour","Text":"Blue"},
"RootName_1":{"Id":1,"ValId":2,"Value":"Colour","Text":"Red"}
};
var colors = [];
for(var key in obj){
colors.push(obj[key]);
};
The value you want is now in the colors array.

Answer 3

Using ES5 (modern browsers) you could do:
Object.keys(received).map(function(key) {
return received[key];
});
Basically, converting the object into an array of its keys, then replacing each key with the value.

Answer 4

In javascript, if myFirstVar contains the initial object, then do:
mySecondVar = [ myFirstVar.RootName_0, myFirstVar.RootName_1 ];

Answer 5

Once the JSON has been parsed, do it using jQuery's jQuery.map, and borrowing the global Object function...
var arr = $.map(obj,Object);
EDIT:
If you do it in JavaScript, you should be aware that the objects may not remain in their original order.
You can remedy this if the RootName_n keys are sequential, and you know the n of the last key.
var last_key = 20;
var arr = [];
for(var i = 0; i <= last_key; i++)
arr.push( obj['RootName_' + i] );
