vue3怎么用$nextTick

在Vue 3中,可以使用`import { nextTick } from 'vue'`来引入`nextTick`方法。在`setup`函数中,可以使用`nextTick`来执行一些异步操作。例如,可以将`visible`变量定义为响应式变量,然后在`nextTick`回调中将其设置为`true`,以确保在更新DOM后再显示它。下面是一个示例代码:
```javascript
import { nextTick } from 'vue'
setup() {
const visible = ref(false)
nextTick(() => {
visible.value = true
})
return {
visible
}
}
```
这样,`visible`变量将会在DOM更新后变为`true`。注意,由于`nextTick`是异步执行的,所以需要在回调函数中进行相关操作。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
