Vue 'created' 生命周期钩子


示例

使用 created 生命周期钩子来更改 'text' 数据属性。

export default {
  data() {
    return {
      text: 'initial text'
    }
  },
  created() {
    this.text = 'The component is now created';
  }
}
运行示例 »

定义和用法

在组件初始化后,会调用 created 生命周期钩子。

由于组件已初始化,我们可以访问组件实例内部的属性,例如 datacomputed,但我们不能访问组件 DOM 元素,因为它们直到 mounted 钩子才会创建。
