Vue.jsで外部HTMLファイルをinclude(っぽく)する

Last updated at Posted at 2020-02-28

概要

Componentに分けたいけど分けられない。諸事情でHTMLファイルをincludeしたい。
HTMLファイルを直接弄りたいとか言われましても

方法

  • 外部HTMLファイルを非同期で読み込んで展開する

具体例

<template>
  <main>
    <section v-html="external"></section>
  </main>
</template>

<script lang="ts">
import { Vue, Component } from "vue-property-decorator";

@Component
export default class App extends Vue {
  external: string = "";

  public mounted() {
    this.loadExternalHtml();
  }
  
  public loadExternalHtml() {
    fetch("external.html").then(res => {
      res.text().then(html => {
        this.external = html;
      });
    });
  }
}

includeっぽくはなる。
これでガリガリHTMLを弄ってもおk
