Question

我正在尝试在Google的Materializecss中调用M.toast()函数，但收到错误消息：

未捕获的ReferenceError：未定义M

index.html

    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">

  <body>
    <form action="#">
      <button class="waves-effect waves-light btn" id="submit" type="submit" name="submit">
        Submit
      </button>
    </form>

    <script type="text/javascript" src="scripts/register.js"></script>

  </body>
</html>

register.js

(function() {
  'use strict';

  $('form').submit(
    function(e) {
      let $radio = $("input:radio[name='myradio']");

      if (!$radio.is(':checked')) {
        e.preventDefault();
        toast();

        return false;
      }
    });

  function toast() {
    M.toast({html: 'Bitte alle Felder auswählen!'});
  }
})();

我忘了包括某些东西或什么事吗？
