Use data into Framework7, Vue and Cordova project

it’s possible use the Jquery and into framework7, Vue and Cordova project?

I try to import jQuery into index.html in this mode:

<script src="" integrity="sha256-CSXorXvZcTkaix6Yvo6HppcZGetbYMGWSFlBw8HfCJo=" crossorigin="anonymous"></script>

and test whit this code:

window.onload = function() {
    if (window.jQuery) {
        // jQuery is loaded
    } else {
        // jQuery is not loaded
        alert("Doesn't Work");

It’s work!!!

If import in the app.js file not work

import JQuery from './js/jquery-3.4.1.min.js';

For local file where i put the file ?

After when try to integrate a datatable i use cdn file:

<link rel="stylesheet" href="">
  <script src="" ></script>

But, when i try to initialize the datatable i have error.

$(document).ready(function() {

What is the error text?

dataTable is not a function.
I think not have imported correctly a datatable js.
