javascript - Vue JS 如何根据数组值删除对象

Question

我有一个对象数组，例如:

types: [
{
 id: 1,
 name: "Hello"
},
{
 id: 2,
 name: "World"
},
{
 id: 3,
 name: "Jon Doe"
}
]

我也有一个像这样的简单数组:

selected_types = [1, 2]

期望的结果应该过滤"types" 数组并排除所有存在于"selected_types" 数组中的id，如下所示:

final_types: [
{
 id: 3,
 name: "Jon Doe"
}
]

我完全不知道如何实现这一点，但下面是我的尝试:

   this.types.filter(obj => {
        for (let i = 0; i < this.selected_types.length; i++) {
          if (obj.id !== selected_types[i]) {
            final_types.push(attribute);
          }
        }
      });

Answer 1

只需使用 this.types.filter(({id}) => !this.selected_types.includes(id)):

let types = [{
    id: 1,
    name: "Hello"
  },
  {
    id: 2,
    name: "World"
  },
  {
    id: 3,
    name: "Jon Doe"
  }
]

let selected_types = [1, 2];
let resArr = types.filter(({id}) => !selected_types.includes(id));
console.log(resArr);
