Here is a simple example HTML-file containing ooRexx code, as "an example may
tell more than 1.000
words":
<head>
<title>Object Rexx: Process User Input</title>
<script language="Object Rexx">
::routine do_some_work public
output~innerhtml=reverse(input~value)
</script>
</head>
<body>
Please enter some text:<p>
<input id="input" type="textarea" size="100"> <BR>
<input type="BUTTON" onclick="call do_some_work" language="Object Rexx"
value="Please Press Me!"><p>
<p id="output">
</body>
If you save the examle in a file named "test.html" and load this HTML-file with
MS Internet Explorer
on Windows XP with ooRexx 3.2 installed, then:
* an input field is displayed into which a user may enter text,
* a push button is displayed reading "Please Press Me!",
o when pressing the push button, then the input text is fetched (via its
id "input") and
reversed by Rexx and re-displayed in the empty paragraph with the id
"output".
You can repeat the actions as many times as you wish.
On W7, after pressing the push button, MSIE reports a crash.
