CDNのjQueryをImport Mapsで読み込ませる方法

Posted at

jQueryはもう使わないけど、一例として、、

index.html
<!DOCTYPE html>
<head>
  <meta charset="UTF-8" />
  <meta http-equiv="X-UA-Compatible" content="IE=edge" />
  <meta name="viewport" content="width=device-width, initial-scale=1.0" />
  <title>Sample Import Maps</title>
  <script type="importmap">
    {
      "imports": {
        "jQuery": "https://code.jquery.com/jquery-3.3.1.js"
      }
    }
  </script>
  <script type="module" src="./js/sample.js"></script>
</head>
<body>
  
  <div id="count">0</div>
  <input type="button" id="up" value="+">
  <input type="button" id="minus" value="-">

</body>

sample.js
"use strict";

import 'jQuery';

$(window).on('load', function(){
    console.log('loaded!');

    let count = 0

    $('#up').on('click', function () {
        $('#count').html(++count)
    })
    $('#minus').on('click', function () {
        $('#count').html(--count)
    })
})
  • jQuery以外のCDNでも使えそう
  • CDNでなくてもローカルのJSファイルもできる
  • 検索しても情報が少ない
  • ES Modulesで書いてるのでindex.htmlはWebサーバー環境で見てください
