How to add external script to vue component?

Question

I need your help very much... I have a Vue component and endpoint which gives me a script with a small menu and that script includes some actions. So, after my script is loaded its actions don't work on a page and I don't know why. Below the example code:

<template>
  <div id="menu"></div>
</template>

<script>
export default {
  name: 'HelloWorld',
  data () {
    return {
      msg: 'Welcome to Your Vue.js App'
    }
  },
  mounted () {
    // here I get a script which contains menu bar with actions
    // css and styles 
    this.$http.get("https://endpointwithscript.com/menu").then(response => {
      if (response.status === 200) {
        //in that case script doesn't work. Eg click
        var div = document.getElementById("menu")
        div.innerHTML += response.body;
        document.appendChild(div);
      }
    })
  }
}
</script>

If I insert my downloaded script that way :

mounted () {
    this.$http.get("https://endpointwithscript.com/menu").then(response => {
      if (response.status === 200) {
        document.write(response.body);
      }
    })
  }

then script works but another html elements are overridden by that script and not displayed. How to download script, insert it on a page and keep all functionality ? Thank you!

@BoussadjraBrahim tag <script type="text/javascript">, css and I guess some html elements . Don't remember exactly — dippy tippy

so you could build a component using that content, import it and use it in this code — Boussadjra Brahim

@BoussadjraBrahim Yes, it's a good idea. But how to build it properly. I can use var div = document.getElementById("menu") div.innerHTML += response.body; document.appendChild(div); but then actions don't work — dippy tippy

You can try adding your external script into Mounted()

mounted() {
  let yourScript= document.createElement('script')
  yourScript.setAttribute('src', 'https://endpointwithscript.com/menu')
  document.head.appendChild(yourScript)
},

<div class="menu"></div> var div = document.getElementById("menu")

You are grabbing the element by ID, but gave it a class instead. Change the div to be <div id="menu"></div>

Thanks. But it's only a typo.

Can you try using the v-html directive? <span v-html="script"></span> Add the script property to component data, then when you fetch the script assign it to that property and the component should update.

@BrandonLyons Boussadjra Brahim is right. The idea to display the content and keep event functionality .

You could use v-html to include HTML-Code into a specific tag.

It seems the only way to implement a working script is by defining a new script element.

This worked for me here https://jsfiddle.net/nh475cq2/

new Vue({
  el: "#app",
  mounted () {
  this.$http.get("https://gist.githubusercontent.com/blurrryy/8f7e9b6a74d1455b23989a7d5b094f3f/raw/921937ea99ff233dfc78add22e18868b32cd11c0/Test").then(res => {
  if(res.status === 200) {
    let scr = document.createElement('script');
    scr.innerHTML = res.body;
    document.body.appendChild(scr);
  }
  })
  }
})
