好吧，这是我在qiokian(一个live2d动画人物vuejs组件)中的实践:

(以下来自src/qiokian.vue文件)

<script>
export default {
    data() {
        return {
            live2d_path:
                'https://cdn.jsdelivr.net/gh/knowscount/live2d-widget@latest/',
            cdnPath: 'https://cdn.jsdelivr.net/gh/fghrsh/live2d_api/',
        }
    },
<!-- ... -->
        loadAssets() {
            // load waifu.css live2d.min.js waifu-tips.js
            if (screen.width >= 768) {
                Promise.all([
                    this.loadExternalResource(
                        this.live2d_path + 'waifu.css',
                        'css'
                    ),
<!-- ... -->
        loadExternalResource(url, type) {
            // note: live2d_path parameter should be an absolute path
            // const live2d_path =
            //   "https://cdn.jsdelivr.net/gh/knowscount/live2d-widget@latest/";
            //const live2d_path = "/live2d-widget/";
            return new Promise((resolve, reject) => {
                let tag

                if (type === 'css') {
                    tag = document.createElement('link')
                    tag.rel = 'stylesheet'
                    tag.href = url
                } else if (type === 'js') {
                    tag = document.createElement('script')
                    tag.src = url
                }
                if (tag) {
                    tag.onload = () => resolve(url)
                    tag.onerror = () => reject(url)
                    document.head.appendChild(tag)
                }
            })
        },
    },
}

好吧，这是我在qiokian(一个live2d动画人物vuejs组件)中的实践:

(以下来自src/qiokian.vue文件)

<script>
export default {
    data() {
        return {

            return new Promise((resolve, reject) => {
                let tag

                if (type === 'css') {
                    tag = document.createElement('link')
                    tag.rel = 'stylesheet'
                    tag.href = url
                } else if (type === 'js') {
                    tag = document.createElement('script')
                    tag.src = url
                }
                if (tag) {
                    tag.onload = () => resolve(url)
                    tag.onerror = () => reject(url)
                    document.head.appendChild(tag)
                }
            })
        },
    },
}

您可以使用vue-head包将脚本和其他标记添加到vue组件的头部。

很简单:

var myComponent = Vue.extend({
  data: function () {
    return {
      ...
    }
  },
  head: {
    title: {
      inner: 'It will be a pleasure'
    },
    // Meta tags
    meta: [
      { name: 'application-name', content: 'Name of my application' },
      { name: 'description', content: 'A description of the page', id: 'desc' }, // id to replace intead of create element
      // ...
      // Twitter
      { name: 'twitter:title', content: 'Content Title' },
      // with shorthand
      { n: 'twitter:description', c: 'Content description less than 200 characters'},
      // ...
      // Google+ / Schema.org
      { itemprop: 'name', content: 'Content Title' },
      { itemprop: 'description', content: 'Content Title' },
      // ...
      // Facebook / Open Graph
      { property: 'fb:app_id', content: '123456789' },
      { property: 'og:title', content: 'Content Title' },
      // with shorthand
      { p: 'og:image', c: 'https://example.com/image.jpg' },
      // ...
    ],
    // link tags
    link: [
      { rel: 'canonical', href: 'http://example.com/#!/contact/', id: 'canonical' },
      { rel: 'author', href: 'author', undo: false }, // undo property - not to remove the element
      { rel: 'icon', href: require('./path/to/icon-16.png'), sizes: '16x16', type: 'image/png' }, 
      // with shorthand
      { r: 'icon', h: 'path/to/icon-32.png', sz: '32x32', t: 'image/png' },
      // ...
    ],
    script: [
      { type: 'text/javascript', src: 'cdn/to/script.js', async: true, body: true}, // Insert in body
      // with shorthand
      { t: 'application/ld+json', i: '{ "@context": "http://schema.org" }' },
      // ...
    ],
    style: [
      { type: 'text/css', inner: 'body { background-color: #000; color: #fff}', undo: false },
      // ...
    ]
  }
})

为了保持组件的干净，你可以使用mixin。

在组件上导入外部mixin文件。

Profile.vue

import externalJs from '@client/mixins/externalJs';

export default{
  mounted(){
    this.externalJsFiles();
  }
}

externalJs.js

import('@JSassets/js/file-upload.js').then(mod => {
  // your JS elements 
})

babelrc(我包括这个，如果任何导入卡住)

{
  "presets":["@babel/preset-env"],
  "plugins":[
    [
     "module-resolver", {
       "root": ["./"],
       alias : {
         "@client": "./client",
         "@JSassets": "./server/public",
       }
     }
    ]
}

您是否正在使用vue的Webpack入门模板(https://github.com/vuejs-templates/webpack)?vue-loader (https://github.com/vuejs/vue-loader)已经设置好了。如果你不使用启动器模板，你必须设置webpack和vue-loader。

然后，您可以将脚本导入到相关的(单个文件)组件。在此之前，你必须从脚本中导出你想导入到组件中的内容。

~编辑~ 你可以从这些包装器中导入: ——https://github.com/matfish2/vue-stripe ——https://github.com/khoanguyen96/vue-paypal-checkout

这可以像这样简单地完成。

  created() {
    var scripts = [
      "https://cloudfront.net/js/jquery-3.4.1.min.js",
      "js/local.js"
    ];
    scripts.forEach(script => {
      let tag = document.createElement("script");
      tag.setAttribute("src", script);
      document.head.appendChild(tag);
    });
  }
