Sort Array Both Ascending And Descending Using Jquery

I am trying to sort my array, both ascending and descending. I cant seem to figure out how to do this correctly though. I tried with different methods, but none worked. This is su

Solution 1:

As you're sorting an array of arrays rather than sorting just a series of names, you'll need to do something slightly different for sorting.

Try using something such as this:

function arrSort(arr, subkey){
  //Default to 0 if no subkey is set
  subkey = (subkey===undefined?0:subkey);

  var a = arr.slice(0),
      b = [], x;

  //For each section in the array, create an array containing whatever we are trying to sort by and our unique ID
  for (x in a){
    b[x]=[a[x][subkey], x];
  }

  b=b.sort();

  //Wipe out all the data that's currently in arr!
  arr.splice(0, arr.length);

  for (x in b){
    arr.push(a[b[x][1]]);
  }
  return arr;
}

I believe you'd be wanting to sort by $titel so you'd want to implement this something like this:

// kör funktionen när knappen med id stigande klickas
$('#stigande').click(function(a,b){
  arrSort($films, 0);
});

// kör funktionen när knappen med id fallande klickas
$('#fallande').click(function(){
  arrSort($films, 0);
  $films.reverse();   
});
