如何更改数组对象属性值javascript

Question

我有一个数组对象和一个数组。该数组中的哪些值与数组对象中的值匹配需要更改状态（如 true）。

arrObj 输出应如下所示：

[
    { name: "Test1", status: true }, 
    { name: "Test2", status: false }, 
    { name: "Test3", status: true }
]

演示：https://stackblitz.com/edit/github-7plax5-mu3l6a?file=src%2Fapp%2Fapp.component.ts

<code>let arrObj = [{
    name: "Test1",
    status: true
  },
  {
    name: "Test2",
    status: true
  },
  {
    name: "Test3",
    status: true
  }
]

let arr = ["Test1", "Test3"];

for (k of arr) {
  if (arrObj.name == k) {
    arrObj.status = true;
  }
}

console.log(arrObj);</code>

修改原始数组的最简单方法

arrObj.forEach(item => item.status = arr.includes(item.name))

console.log(arrObj);

<script>
let arrObj = [{
    name: "Test1",
    status: false
  },
  {
    name: "Test2",
    status: false
  },
  {
    name: "Test3",
    status: false
  }
]

let arr = ["Test1", "Test3"];
</script>
