javascript - remove localstorage array object base on value -


says have saved key in localstorage, how remove player_id has value of 2 , shoe size_of 1?

[{"player_id":1,"shoe_size":3},{"player_id":2,"shoe_size":1},{"player_id":2,"shoe_size":2},

what next after saved value?

if(localstorage["player"]){     player = json.parse(localstorage["player"]); }

you can use .filter()

the filter() method creates new array elements pass test implemented provided function.

player  = player .filter(function( obj ) {     return !(obj.player_id == 2 && obj.shoe_size == 1); });

if want set it:

localstorage["player"] = json.stringify(player) 

var player = [{"player_id":1,"shoe_size":3},{"player_id":2,"shoe_size":1},{"player_id":2,"shoe_size":2}];    player  = player.filter(function(obj) {      return !(obj.player_id == 2 && obj.shoe_size == 1);  });    document.write(json.stringify(player))
