I've got the following object that's an object array (an array of objects), on a variable:

variable: myVar1

On fireBug I get the following lines when I call myVar1:

[Object { myId= "1", myName= "Name1" }, Object { myId= "2", myName= "Name2" }, Object { myId= "3", myName= "Name3" }]

I need this data to be in the followng format stored on a variable too:

myVar2 = [
[1, 'Name1'],
[2, 'Name2'],
[3, 'Name3']
]

I've tried so many things like the use of for loops and js functions but can't get it work. I supose it's so easy. Anyone could try to explain the procedure.

Thank you

Solution for browsers which support Array.map():

var result = arr.map(function(o) { return [+o.myId, o.myName]; });

For compatibility you may use the shim provided at MDN.

Thank you. Only a curiosity: Which browsers does not support array.map() function? –  Calypo Gunn Jan 21 '13 at 17:21

@CalypoGunn IE < 9. You can check it here: kangax.github.com/es5-compat-table. –  VisioN Jan 21 '13 at 17:31

The following should do the trick:

var myVar2 = [];
for (var i = 0; i < myVar1; i++) {
  myVar2.push([myVar1[i].myId, myVar1[i].myName]);
}
