如何将外部 JS 脚本添加到 VueJS 组件? [英] How to add external JS scripts to VueJS Components?

问题描述

我必须为支付网关使用两个外部脚本.

I've to use two external scripts for the payment gateways.

现在两者都放在 index.html 文件中.

Right now both are put in the index.html file.

但是，我不想在一开始就加载这些文件.

However, I don't want to load these files at the beginning itself.

只有在用户打开特定组件时才需要支付网关(using router-view).

The payment gateway is needed only in when user open a specific component (using router-view).

有没有办法做到这一点?

Is there anyway to achieve this?

谢谢.

推荐答案

解决这个问题的一个简单有效的方法，就是将你的外部脚本添加到你组件的 vue mounted() 中.我将用 Google Recaptcha 脚本向您说明:

A simple and effective way to solve this, it's by adding your external script into the vue mounted() of your component. I will illustrate you with the Google Recaptcha script:

<template>
   .... your HTML
</template>

<script>
  export default {
    data: () => ({
      ......data of your component
    }),
    mounted() {
      let recaptchaScript = document.createElement('script')
      recaptchaScript.setAttribute('src', 'https://www.google.com/recaptcha/api.js')
      document.head.appendChild(recaptchaScript)
    },
    methods: {
      ......methods of your component
    }
  }
</script>
