dynamically generating javascript statements

[Volker Hetzer]

Hi!
I'm new to javascript and I'd like to know whether javascript can
process javascript-code entered by the user or read from a file.

We've got an application that uses ActiveX as main customization
means and we'd like to write a javascript control which listens
to a socket, reads a javascript statement accessing some ActiveX classes
and then executes that statement. The applicatoin doesn't know beforehand
which classes are there.

Lots of Greetings!
Volker

Yes, the function
eval
takes a string with JavaScript source code as its arguments and
evaluates the code.

And <URL:http://www.merlyn.demo n.co.uk/js-quick.htm> does just the
former that, when the Eval button is pressed.

H'mmm - it can read from a file, too, if one enters something like


<script type="text/javascript" src="include1.j s">
</script>
<script type="text/javascript">
document.write( LZ(3))
</script>

and presses HTML. Function LZ is supplied by include1.js.
