events on HTML using Javascript

Question

How can I trigger a button in HTML using the javascript?

I tried to use the <script></script> the HTML file and it works perfectly fine, but then I want to use a javascript file to trigger when clicking a button in HTML.

here is the code: JAVASCRIPT in HTML <head></head> tag:

<script src="https://unpkg.com/sweetalert/dist/sweetalert.min.js">
<script src="jsFiles/index.js"></script>

HTML:

             <div class="dropdown-menu">
              <a class="dropdown-item" href="#">Message</a>
              <a class="dropdown-item" href="#">Settings</a>
              <a class="dropdown-item" id="a_id">Log Out</a>
              </div>

JAVASCRIPT FILE:

<script src="https://unpkg.com/sweetalert/dist/sweetalert.min.js"></script>
    $(document).ready(function(){
        $("#a_id").click(function(){

            swal({title:'Logout', 
            text:'Do you want to logout this Account?', 
            icon:'warning', 
            buttons: true, 
            dangerMode: true
            })
            .then((willOUT) => {
                if (willOUT) {
                    window.location.href = 'page-logout.php', {
                    icon: 'success',
            }
            }
            });

            });
    });
</script>

You don't appear to have included jQuery, yet are using jQuery methods. — Obsidian Age

@AlexAbulencia put <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> in your html right above your <script src="jsFiles/index.js"></script> and try it then. jQuery wouldn't work if you don't include it, which is what Obsidian Age is saying — Aniket G

You should remove everything is not javascript code, so your file index.js should look as follow:

$(document).ready(function() {
  $("#a_id").click(function() {

    swal({
        title: 'Logout',
        text: 'Do you want to logout this Account?',
        icon: 'warning',
        buttons: true,
        dangerMode: true
      })
      .then((willOUT) => {
        if (willOUT) {
          window.location.href = 'page-logout.php', {
            icon: 'success',
          }
        }
      });

  });
});
