    Resolved [RESOLVED] script executing issue

    So I am executing a XMLHttpRequest on button click. For some time, the user will not see any progress or status of the response.

    The response may take awhile on receiving the reaponse.

    How can we show to the user the progress or status of the request?

    Based on your design in this thread: https://www.vbforums.com/showthread....-you-loop-this

    One option is to create a "status" element and then update the element's text as the code progresses, e.g.:
    Code:
    // <p id="status"></p> in your HTML
    function loadXMLDoc() {
      const status = document.getElementById('status'); 
      const xhttp = new XMLHttpRequest();
      xhttp.onreadystatechange = function() {
        if (xhttp.readyState !== 4 || xhttp.status !== 200 || !xhttp.responseText) {
          status.innerText = 'Request failed';
          loadXMLDoc();
          return;
        }
        status.innerText = 'Request finished';
        document.getElementById('p1').innerHTML = xhttp.responseText;
      };
      status.innerText = 'Request starting...';
      xhttp.open("POST", "manage.php", true);
      xhttp.send();
    }
    Alternatively it may be worth just showing/hiding a progress indicator like this: https://getbootstrap.com/docs/5.1/components/spinners/
