子组件怎么拿到父组件的值
时间: 2023-09-09 20:11:01 浏览: 68
子组件可以通过props属性来接收父组件传递的值。在Vue中,父组件可以通过动态绑定数据将值传递给子组件。在子组件中,可以通过props来声明接收的属性,然后在子组件中使用这些属性。
例如,如果父组件传递一个名为"todos"的属性给子组件,子组件可以像这样接收并使用这个值:
```javascript
props: ['todos'],
```
然后在子组件中就可以通过`this.todos`来访问父组件传递的值了。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
