jquery - Alternative way to sort JSON file or at least, a drop-down list using javascript? -

is there alternative way sort json file or @ least, drop-down list other following code?

json.sort(function(a, b){     return a.id - b.id; }); 

the reason takes long sort json file containing countries in world. here code:

parsejsonfile("json/country.json", function(data) {             data.sort(sortcountryname);             localstorage.setitem("country", json.stringify(data));          });  // function sorting countries function sortcountryname(a,b){      return a.spanish.tolowercase() > b.spanish.tolowercase() ? 1 : -1; } 

**update: here small part of json file:

{     "code" : "please select country",     "english" : "-- please select country --",     "spanish" : "-- por favor seleccione el pa&#237s --" }, {     "code" : "afg",     "english" : "afghanistan",     "spanish" : "afganist&#225n" }, {     "code" : "alb",     "english" : "albania",     "spanish" : "albania" }, {     "code" : "dza",     "english" : "algeria",     "spanish" : "argelia" }, {     "code" : "asm",     "english" : "american samoa",     "spanish" : "samoa americana" }, 

if can modify json, make sorted in first place @undefined said, user downloads sorted array. if can't, precalculate sort field number of calculations reduced:

var header = data.shift(); data.foreach(function(item) { item.sortkey = item.spanish.tolowercase(); }); data.sort(function(a, b) {   var aa = a.sortkey;   var bb = b.sortkey;   if (aa == bb) return 0;   return (aa < bb) ? -1 : 1; }); data.unshift(header); 

also, make sure 2 seconds sorting delay , not loading delay. there's not can loading delay apart processing data serverside reduce memory footprint (e.g. compressing transport, pruning specified ui language...)
