Is there a simple way, using filter or parse or something else to convert an array like the following :

var someJsonArray = [

  {id: 0, name: name, property: value, otherproperties: othervalues},

  {id: 1, name: name1, property: value1, otherproperties: othervalues1},

  {id: 2, name: name2, property: value2, otherproperties: othervalues2}

];

into a simple array filled with one attribute of the objects contained in the previous array like this :

[0, 1, 2]

Use .map() function:

finalArray = someJsonArray.map(function (obj) {

  return obj.id;

});

Snippet

var someJsonArray = [

  {id: 0, name: name, property: value, therproperties: othervalues},

  {id: 1, name: name1, property: value1, otherproperties: othervalues1},

  {id: 2, name: name2, property: value2, otherproperties: othervalues2}

];

var finalArray = someJsonArray.map(function (obj) {

  return obj.id;

});

console.log(finalArray);

The above snippet is changed to make it work.
