親から子へのデータ受け渡し

プロパティを使う

  • 子コンポーネントにprops["fooBar"] を定義
  • 子コンポーネントtemplateでプロパティを使った描画を行う (data変数と同じ扱いでよい)
  • 親コンポーネントで子コンポーネントのカスタムタグを使用する際、v-bind (:) で子プロパティを指定し値をバインディングする。
  • 親から子コンポーネントのプロパティ名を指定する時にはケバブケースで指定する。(子コンポーネントに値が渡る際に自動的にキャメルケースのプロパティ名に紐づけられる。

子 Component

const childComponent2 = {
  template:`
  <div>
    <input type="text" v-model="myValue">
    {{myValue}}
  </div>`,
  props: ["myValue"]
}

親 template

<child2 :my-value="parentValue"></child2>

子のイベントを購読する

購読には v-on (@)を使う

  • 親子でイベント名を共有する (例では on-child-component1-updated)
  • 親コンポーネントはイベント名にメソッドを紐づけておく。
  • 子コンポーネントはイベント発生時にイベント名を使って親へ emit する
  • emitされるイベント名に紐づいている親コンポーネントのメソッドが引数つきコールされる。

子 Component

const childComponent1 = {
  template: `
  <div>
    <input type="text" v-model="myValue" @input="updated">
     {{myValue}}
  </div>`,
  data: function () {
    return {
      myValue: ""
    }
  },
  methods: {
    updated: function () {
      //イベント名を介して親のメソッドへコールバックする。
      this.$emit("on-child-component1-updated", this.myValue)
    }
  }
}
