Pass url parameter to js using laravel route or controller

I have a Vue table - I would like to select an item in a row and then load a page that shows the details for the item using Chart.js

I can select the item and load the json for the selected record OR I can load the page passing the url and hard code a record ID in the js file - struggling to understand how to load the detail passing the record ID.

To load the json for the record the following code works: . . .

    <tbody>
      <tr v-for="item in items | filterBy searchText | orderBy sortparam order">
        <td>@{{item.provider_name}}"</td>
        <td>@{{item.city}}</td>
        <td>@{{item.rating}} %</td>
        <td>@{{item.discussed}} %</td>
        <td>@{{item.communicated}} %</td>
        <td>@{{item.professional}} %</td>
        <td><a href="/surveyvisual/@{{item.ccn}}" > @{{item.ccn}}  </a></td>
      </tr>
    </tbody>

...

And to return the json

...

public function show($ccn)
{
    $ccn = Provider::where('ccn', '=', $ccn)->get()->toArray();

}

...

If I hard code the parameter in the js file rendering the chart then I can load the page and show the details - the following code brings in the correct data

...

var apiVisURL = '[url to return json]';

function test() {
  return $.getJSON(apiVisURL + '77001');
}

$.when(test()).then(function (myData) {
var canvas = document.querySelector('canvas');
fitToContainer(canvas);

    function fitToContainer(canvas){
  // Make it visually fill the positioned parent
  canvas.style.width ='50%';
  canvas.style.height='100%';
  // ...then set the internal size to match
  canvas.width  = canvas.offsetWidth;
  canvas.height = canvas.offsetHeight;
}
    Array.prototype.mapProperty = function(property) {
      return this.map(function (obj) {
      return obj[property];
   });
 };

...

Obviously more code in the above to set al the data elements of the chart - and the chart renders correctly for the record I have hardcoded.

Any hints or recommendations on how to pass the selected record id to the js file building the chart appreciated.

UPDATE: I should have stated that I have to js files - one for the Vue to render the table and one for the Chart.
