How to tell which <p> 'id=' has focus ?
Hello & Thanks ,
The problem with 'document.activeElement.tagname' is that
for p element it returns 'BODY' .
But I want to know which p has focus .
Pls, How can this be done ?
Here is the prototype function I was working on .

<!DOCTYPE html>
<html>
<title>Which Element Has Focus</title>
<!--
-->
<body onload="documentURL()" onclick="myFunction()" >

<p>Click anywhere in the document to display the active element.</p>
<input type="text" value="An input field">
<button>A Button</button>

    <p id="demo">Who dunnit ?</p>
    <br>
    <p id="currentPage_Address" style="fontsize: 12px; color: #34495E;">Current Page Address</p>
<script>
function myFunction() {
  var x = document.activeElement.tagName;
  document.getElementById("demo").innerHTML = x;
}
</script>
      <script>
         var  p_tgh = "";
         var  pp_tgh = "";
         var  p_tghCount = 1;
         var  p_ah = "";
         var  pp_ah = "";
         var  p_ahCount = 1;
         var  ArticleHeading = "Heading";
         var  TextParagraph = "Text Paragraph";
         var  ButtonParagraph = "New Link";
         var  document_URL;
         const  filename = "myStory.html";
         var allHtml =  document.documentElement.outerHTML; 
         var  document_URL;
         function documentURL() {
         document_URL = document.URL;
         document.getElementById("currentPage_Address").innerHTML = document_URL;  
//         window.addEventListener("keydown", onPress_ENTER, false);
         }
      </script>

</body>
</html>

And I would like to put some working code in here:
'function onPress_ENTER(event)'
Triggered by this:
'window.addEventListener("keydown", onPress_ENTER'
Here is the full code where I want to put "WhichParaHasFocus".

<!DOCTYPE  html>  
<html>
   <head>
      <meta charset="UTF-8">
      <meta name="viewport" content="width=device-width, initial-scale=1.0">
      <title>MyStory.html</title>

         </a>
         still to do: intercept 'enter-key' replace with 8 spaces ELSE just cancel it .

If you want a paragraph to be focusable, you'll have to give it a tabindex attribute with a non-negative value.

Thanks Ingolme

I checked it out , but I don't want to dabble with tabindex .

I came up with a workaround that works for me:

Hmm...

This is pretty cool too (double whamy):

<p contenteditable="" id="p_ah1" onfocus="{has_Focus = 'p_ah1'}; console.log(has_Focus); " onclick="{has_Focus = 'p_ah1'}">Heading</p>

Might want to consider location.hash, you can retrieve what was clicked and use css to highlight it!
