的$ scope.categories阵列正被从在AngularJS多选择元件填充.

$scope.categories = ["Adventure", "Strategy"]

我需要将此数组与下面的items数组中的categories数组进行比较:

$scope.items = [
    {
        title: "Star Wars",
        categories: ["Adventure"]
    }, {
        title: "Star Search",
        categories: ["Adventure", "Strategy"]
    }, {
        title: "Star Trek",
        categories: ["Adventure", "Family"]
    }, {
    title: "Star Wars",
    categories: ["Family", "Strategy"]
}];

在这两个值$ scope.categories需要匹配在相同的值$ scope.items.categories,对象被推向一个输出阵列.

生成的$ scope.filtered数组为(项1):

{
  title: "Star Search",
  categories: ["Adventure", "Strategy"]
}

我有逻辑,直到循环需要重申......但是如何？

1. 我循环遍历$ scope.categories
2. 然后循环遍历$ scope.items
3. 然后循环遍历每个对象的$ scope.item.categories数组.

4. 然后我比较$ scope.categories对价值价值$ scope.item.categories

   for …
