Thanks for the quick reply!  Couple questions:

- did you just copy paste my code above into an 'html 5' page?
- i'm using an iPas air (OS 7.1.2), any issue with this version and your version of Textastic?
- are there any setting I need to have turned on / be aware of for this to work?

I still just get a blank page w/ nothing...

Vielen Dank für die Hilfe!
For example, the below code doesn't work...any ideas? Seems too basic to not work.

<!DOCTYPE html>
<html>
<body>

<p>Click the button to display an alert box:</p>

<button onclick="myFunction()">Try it</button>

<script>
function myFunction() {
alert("I am an alert box!");
}
</script>


</body>
</html>
