Question

我在本地存储中有这个保存的密钥，如何删除值为2且鞋尺寸为1的player_id？

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

获得保存的值后，下一步该怎么做？

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

您可以使用.filter()

filter（）方法创建一个新数组，其中包含通过所提供函数实现的测试的所有元素。

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

如果你想设置它：

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))

基于值删除localstorage数组对象
