Bootstrap modal does not show with microsoft visual studio – Jquery

I have the following code copy-pasted from w3schools Modal training page .

    <!DOCTYPE html>
<html lang="en">
<head>
    <title>Bootstrap Example</title>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/css/bootstrap.min.css">
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
    <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/js/bootstrap.min.js"></script>
</head>
<body>

    <div class="container">
        <h2>Activate Modal with JavaScript</h2>
        <!-- Trigger the modal with a button -->
        <button type="button" class="btn btn-info btn-lg" id="myBtn">Open Modal</button>

        <!-- Modal -->
        <div class="modal fade" id="myModal" role="dialog">
            <div class="modal-dialog">

                <!-- Modal content-->
                <div class="modal-content">
                    <div class="modal-header">
                        <button type="button" class="close" data-dismiss="modal">&times;</button>
                        <h4 class="modal-title">Modal Header</h4>
                    </div>
                    <div class="modal-body">
                        <p>Some text in the modal.</p>
                    </div>
                    <div class="modal-footer">
                        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
                    </div>
                </div>

            </div>
        </div>

    </div>

    <script>
        $(document).ready(function () { $("#myBtn").click(function () { $("#myModal").modal('show'); }); });
    </script>

</body>
</html>

I am using MS Visual studio 2019, with Jquery nuget package installed in the project. I simply copy the code to test it in the razor blank page, execute , then I get nothing apart from the button, when it is clicked , no modal appears.

Nevertheless, that code works for the online html compilers.

Am I missing something here ?

    Problem solved :

    Just added :

    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>

    Now the modal is show upon clicking the button.

    The code works on Visual studio and looks like this now :

        <!DOCTYPE html>
<html lang="en">
<head>
    <title>Bootstrap Example</title>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1" />
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
</head>

<body>
    <div class="container">
        <h2>Activate Modal with JavaScript</h2>
        <!-- Trigger the modal with a button -->
        <button type="button"
                class="btn btn-info btn-lg"
                id="myBtn">
            Open Modal
        </button>

        <!-- Modal -->
        <div class="modal fade" id="myModal" role="dialog">
            <div class="modal-dialog">
                <!-- Modal content-->
                <div class="modal-content">
                    <div class="modal-header">
                        <button type="button" class="close" data-dismiss="modal">
                            &times;
                        </button>
                        <h4 class="modal-title">Modal Header</h4>
                    </div>
                    <div class="modal-body">
                        <p>Some text in the modal.</p>
                    </div>
                    <div class="modal-footer">
                        <button type="button"
                                class="btn btn-default"
                                data-dismiss="modal">
                            Close
                        </button>
                    </div>
                </div>
            </div>
        </div>
    </div>

    <script>
        $(document).ready(function () { $("#myBtn").click(function () { $("#myModal").modal('show'); }); });
    </script>

    Try to use bootstrap custom attribute to trigger the modal like below:

    <button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal" id="myBtn">Open Modal</button>

    use data-toggle and data-target in button tag.

    I have edited your code. use data-toggle="modal" and data-target="#YOUR_MODAL_ID" in the button to make it work.

    Here YOUR_MODAL_ID=myModal

    Example using from HTML tag

    <!DOCTYPE html>
<html lang="en">
  <head>
    <title>Bootstrap Example</title>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1" />
    <link
      rel="stylesheet"
      href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/css/bootstrap.min.css"
    />
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
    <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/js/bootstrap.min.js"></script>
  </head>

  <body>
    <div class="container">
      <h2>Activate Modal with JavaScript</h2>
      <!-- Trigger the modal with a button -->
      <button
        type="button"
        class="btn btn-info btn-lg"
        data-toggle="modal"
        data-target="#myModal"
        id="myBtn"
      >
        Open Modal
      </button>

      <!-- Modal -->
      <div class="modal fade" id="myModal" role="dialog">
        <div class="modal-dialog">
          <!-- Modal content-->
          <div class="modal-content">
            <div class="modal-header">
              <button type="button" class="close" data-dismiss="modal">
                &times;
              </button>
              <h4 class="modal-title">Modal Header</h4>
            </div>
            <div class="modal-body">
              <p>Some text in the modal.</p>
            </div>
            <div class="modal-footer">
              <button
                type="button"
                class="btn btn-default"
                data-dismiss="modal"
              >
                Close
              </button>
            </div>
          </div>
        </div>
      </div>
    </div>
