javascript - All local storage items -

i want show of keys , storage written before. code below. created function (allstorage) doesn't work. how can this?

    function storeuserscribble(id) {         var scribble = document.getelementbyid('scribble').innerhtml;         localstorage.setitem('userscribble',scribble);     }      function getuserscribble() {         if ( localstorage.getitem('userscribble')) {             var scribble = localstorage.getitem('userscribble');         }         else {             var scribble = 'you can scribble directly on sticky... , remember message next time visit blog!';         }         document.getelementbyid('scribble').innerhtml = scribble;     }      function clearlocal() {         localstorage.clear();         return false;     }      function allstorage() {         var archive = [];         (var = 0; i<localstorage.length; i++) {             archive[i] = localstorage.getitem(localstorage.key(i));         }     } 

if modify function can list items based on key (will list items only):

function allstorage() {      var values = [],         keys = object.keys(localstorage),         = keys.length;      while ( i-- ) {         values.push( localstorage.getitem(keys[i]) );     }      return values; } 

object.keys new addition javascript (ecmascript 5). lists own keys on object faster using for-in loop option this.

however, not show keys. need return object instead of array (which rather point-less imo bring far before localstorage different object - example's sake):

function allstorage() {      var archive = {}, // notice change here         keys = object.keys(localstorage),         = keys.length;      while ( i-- ) {         archive[ keys[i] ] = localstorage.getitem( keys[i] );     }      return archive; } 

if want compact format listing instead - here each item in array have key=item later can split pairs , forth:

function allstorage() {      var archive = [],         keys = object.keys(localstorage),         = 0, key;      (; key = keys[i]; i++) {         archive.push( key + '=' + localstorage.getitem(key));     }      return archive; }
