How to import .js that imported .json from html

I am not an English-speaking citizen, I am not good at English but I did best.

I am trying to import a js file that imported json from html

.js

import JSON from '../json/menu.json';

(function () {
  function parseMenu(ul, menu) {
    for (var i=0;i<menu.length;i++) {
      if(menu.sub == null) {
        menu.sort(function(a, b) {
          return a.id > b.id ? -1 : a.id > b.id ? 1 : 0;
        });
      }
      var li=$(ul).append('<li><a href="'+menu[i].link+'">'+menu[i].name+'</a></li>');
      if (menu[i].sub!=null) {
        var subul=$('<ul id="submenu'+menu[i].link+'"></ul>');
        $(li).append(subul);
        parseMenu($(subul), menu[i].sub);
      }
    }
  }
  var menu=$('#menu');
  parseMenu(menu, JSON);
});

.json form

[ {
     {
     },
     {
     }
   },
   {
     {
     },
     {
     }
   },
   {
   }
]

I tried like

<script type="module" src="../js/left.js"></script>
<script type="module" src="../json/menu.json"></script>

in html

But I get the following error Failed to load module script: Expected a JavaScript module script but the server responded with a MIME type of "application/json". Strict MIME type checking is enforced for module scripts per HTML spec. in .json

I solved it.

First. Changed name of variable. JSON to menus

Second. Deleted <script type="module" src="../js/left.mjs"></script>

Last. Changed import JSON from '../json/menu.json'; to import menus from '../json/menus.json' assert { type: "json" };

assert is deprecated. Use with instead.

import JSON from '../json/menu.json' with { type: "json" };

const { default: jsonData } = await import("./data.json", { assert: { type: "json" } })

My guess is you are actually trying to use the .js as src in this part:

<script type="module" src="../json/menu.json"></script>

Chrome currently supports https://github.com/tc39/proposal-import-assertions. This allows you to tell the browser that you are importing a json file:

import JSON from '../json/menu.json' assert { type: "json" };

By the way you shouldn't use JSON as the name of variable because it is a built-in object: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON
