I am going to use package(jspdf) loaded from **CDN **

this is CDN

<script src=".5.1/jspdf.umd.min.js"></script>

and I have loaded it like this in a page :

mounted() {
  if (document.getElementById('myScript')) { return }
  let src = '.5.1/jspdf.umd.min.js'
  let script = document.createElement('script')
  script.setAttribute('src', src)
  script.setAttribute('type', 'text/javascript')
  script.setAttribute('id', 'myScript')
  document.head.appendChild(script)
}

and I have a button that when you click on it a below method will called and some pdf will be generated.

generateReport() {
  var doc = new jsPDF('l', 'mm', [62, 32])
  const margins = {
    top: 0,
    bottom: 60,
    left: 0,
    width: 122
  }

  doc.fromHTML(this.$refs.print, margins.left, margins.top, {
    width: margins.width
  })

  doc.save('test.pdf')
}

BUT I get an error

So, how can I fix this error?

• javascript
• vue.js
• nuxt.js
• jspdf

• 1 You loaded the CDN but where is the jsPDF variable declaration? – Diesan Romero Commented Mar 9, 2022 at 17:32
• Does this answer your question? How to add a 3rd party script code into Nuxt? – kissu Commented Mar 9, 2022 at 17:33
• Also, are you sure that you want to use a CDN here? Pretty sure you can find the NPM package for that, it will be far better in a package.json tbh. – kissu Commented Mar 9, 2022 at 17:34
• @DiesanRomero , variable declaration ? how can i do it ? – morteza mortezaie Commented Mar 9, 2022 at 17:35
• @kissu i a pretty sure that this way that i used cdn is worked because i can see that script is loaded , the problem is how to use it – morteza mortezaie Commented Mar 9, 2022 at 17:37

You can use const { jsPDF } = window.jspdf; as shown in the official documentation if you want to use the CDN.

Even tho, I still do remend the NPM package way (so does the package itself).

This one seems to be working :

   <script src="https://cdnjs.cloudflare./ajax/libs/jspdf/1.4.1/jspdf.debug.js"></script>
