这是某个 Angular 色库存中某些元素的 json 对象。关键基本上是该库存中的元素槽 ID。我想要的是根据 AngularJS 中缺少的键填充空数组。例如，如果您采用前 2 个项目，第一个项目有 0 键，第二个项目有键 4，因此缺少 1,2,3，我想用这些缺少的键填充空数组。我希望重复这个过程，直到最多 255 个数组!任何人都可以帮我提供代码或其他东西吗？

最佳答案

你可以这样做:

for( var i=0;i<255;i++){
    if(inventory.data[i] == undefined){
        inventory.data[i] = {};
    }
}

我假设您想要将空对象分配给不存在的键。
