javascript, sort 2 array dependently

Question

for hours i\'ve been trying to figure out how to sort 2 array dependently.

Let\'s say I have 2 arrays.

First one:

array1 = [\'zzzzz\', \'aaaa         


        

Answer 1

It just so happens I had some old code lying around that might do the trick:

function arrVirtualSortGetIndices(array,fnCompare){
    var index=array.map(function(e,i,a){return i;});
    fnCompare=fnCompare || defaultStringCompare;
    var idxCompare=function (aa,bb){return fnCompare(array[aa],array[bb]);};
    index.sort(idxCompare);
    return index;

    function defaultStringCompare(aa,bb){
        if(aa

Sorry, I don't do 'fors'. At least not when I don't have to.

And fiddle.

Also, an alternative fiddle that sorts the results when given an array of objects like this:

given:

var list = [
    {str:'zzzzz',value:3},
    {str:'aaaaa',value:7},
    {str:'ccccc',value:1}
];

outputs:

[
  {str: "aaaaa", value: 7},
  {str: "ccccc", value: 1},
  {str: "zzzzz", value: 3}
]
