中如何使用?
在Vue 3中,this.$nextTick()方法已经被替换为nextTick()方法。它仍然用于在DOM更新之后执行回调函数。以下是在Vue 3中使用nextTick()的示例:
```
import { ref, nextTick } from 'vue'
export default {
setup() {
const abc = ref(false)
function example() {
abc.value = false // 修改数据
nextTick(() => {
// DOM 更新后执行的回调函数
abc.value = true
})
}
return {
abc,
example
}
}
}
```
在上述示例中,我们使用`nextTick()`方法在DOM更新后将`abc`的值设置为`true`。请注意,在Vue 3中,我们使用`ref()`来创建响应式数据。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
