remove localstorage array object base on value

Says I have this saved key in my localstorage, how to remove the player_id that has value of 2 and shoe size_of 1?

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

What to do next after I get the saved value?

if(localStorage["player"]){
    player = JSON.parse(localStorage["player"]);
}

You can use .filter()

The filter() method creates a new array with all elements that pass the test implemented by the provided function.

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

If you want to 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))
