<p>我有一個陣列物件和一個陣列。該數組中的哪些值與數組物件中的值相符需要更改狀態（如 true）。 </p> <p><code>arrObj</code> 輸出應如下圖所示：</p> <pre class="brush:php;toolbar:false;">[ { name: "Test1", status: true }, { name: "Test2", status: false }, { name: "Test3", status: true } ]</pre> <p>示範：https://stackblitz.com/edit/github-7plax5-mu3l6a?file=src/app/app.component.ts</p> <p> <pre class="snippet-code-js lang-js prettyprint-override"><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></pre> </p>

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>
