Javascript.innerHTML is commenting out everything that starts with <?

Does anyone know how can I avoid this text from being commented out when using .innerHTML to display results?

document.getElementById("Final-Result").innerHTML = "This text will appear, <? while this will be commented out ?>";

You can try it out here http://www.w3schools.com/js/tryit.asp?filename=tryjs_comments1

Edit: I need the PHP tags to be there, not for functionality reasons but rather displaying an HTML <code> block with the code snippet, problem is, if I replaced < and > with &lt; and &gt; - the whole HTML block will be represented as text. The other approach is to use RegExp to replace (all) <? and ?> occurrences What would such a RegExp be like?

Thanks.

<? and ?> are shorthand for PHP tags. Why do you want them in an HTML string? Try to wrap them in quotes.

Use innerText or textContent instead of innerHTML, since it's not HTML.

Hi just remove the php tag 

<!DOCTYPE html>
<html>
<body>

<h1 id="myH"></h1>
<p id="myP"></p>

<script>
// Change heading:
document.getElementById("myH").innerHTML = "My First Page";
// Change paragraph:
document.getElementById("myP").innerHTML = "This text will appear, < while this will be commented out >";
</script>

</body>
</html>

This is because you need to encode < > else its trying to parse it as htmltags.

&lt; =  < 
&gt; =  >

http://en.wikipedia.org/wiki/List_of_XML_and_HTML_character_entity_references

In your case this will be written as

document.getElementById("Final-Result").innerHTML = "This text will appear, &lt;? while this will be commented out ?&gt;";
