Keep screen alive and / by user interaction

Questions about Thunkable
1

Hello.

I know that this topic was discussed in this post and in this post and they are marked as Solved, but for me it is not clear yet.

I know that @hhuman posted the solution but I was trying to workaround and to have the webpage / screen in the app activ as the user open the screen without any interaction.

So, the idea is to have the screen active as it opens.
I have removed the button for user interaction and I have the app screen full alive, without any enabling button, BUT it is not working if the user has the phone on Low Battery Mode…
AS I use the version from @hhuman with the button that it is enabled by user, the screen stays alive even if the phone it is on Low Battery Mode.
WHY?

  1. Does anybody has idea how to make it to work even on Low Battery?
  2. Can somebody provide me a solution to have the enabling button under a Thunkable button?

Here is the code from my version, without button with onload function:

<html>
  <head>
    <title>NoSleep.js - Simple Test Page</title>
    <meta name="viewport" content="width=device-width, initial-scale=1">
<script src="NoSleep.min.js"></script>
<script>
      function myFunction() {
  var noSleep = new NoSleep();
       noSleep.enable(); // keep the screen on!
       document.body.style.backgroundColor = "green";
    }
    </script>
  </head>
  <body onload="myFunction()">
    <h1>NoSleep Test Page</h1>
  </body>
</html>

And this is the code from the original version:

<html>
      <head>
        <title>NoSleep.js - Simple Test Page</title>
        <meta name="viewport" content="width=device-width, initial-scale=1">
      </head>
      <body>
        <h1>NoSleep Test Page</h1>
        <script src="NoSleep.min.js"></script>
        <input type="button" id="toggle" value="Wake Lock is disabled" />
        <script>
          var noSleep = new NoSleep();
          var wakeLockEnabled = false;
          var toggleEl = document.querySelector("#toggle");
          toggleEl.addEventListener('click', function() {
            if (!wakeLockEnabled) {
              noSleep.enable(); // keep the screen on!
              wakeLockEnabled = true;
              toggleEl.value = "Wake Lock is enabled";
              document.body.style.backgroundColor = "green";
            } else {
              noSleep.disable(); // let the screen turn off.
              wakeLockEnabled = false;
              toggleEl.value = "Wake Lock is disabled";
              document.body.style.backgroundColor = "";
            }
          }, false);
        </script>
      </body>
    </html>

Any idea?
Thank you!
