+1 for this, simply because its been a very powerful methodology throughout my programming experience with APL's execute function and the expressions of LISP. I certainly agree that power tools are dangerous (especially in these modern days of exploits) but that means you simply have to take care when using them and Trust the source of any that you accept.

Re: [tw] Re: Javascript Interaction with a Textarea
Generally the javascript pulls in data from the input element and pushes the results to a different output element. The native TiddlyWiki way to handle this would be to use data binding: for the JavaScript to pull the data from a tiddler, and have that tiddler bound to an edit control via the edit-text widget. The output would be written to another tiddler, bound to the output element. Although it is an approach that hadn't occurred to me, unfortunately it doesn't seem to work in TW5. I can't tell you why it doesn't. whatever's example doesn't work because TW5 doesn't support inline JavaScript within HTML elements in wikitext. It would be a security risk in some situations as it would mean that any wikitext tiddler might potentially contain executable JavaScript, which may be malicious. TiddlyWiki works very differently than traditional jQuery-style DOM development. I'd recommend the tiddlywiki.com/dev documentation as a good place to start (particularly the material from cjhunt).

[tw] Re: Javascript Interaction with a Textarea
Many of the javascripts that I work with on conventional web-pages use the
general form of an input element of some type, a button to call the
javascript and a separate output element of some type, frequently a
textarea. Generally the javascript pulls in data from the input element and
pushes the results to a different output element. TiddlyWiki’s handling of
javascript seems to be predicated on the idea that the calling element
gathers the input from wherever, passes the parameters to the javascript
which then passes the results back to the calling element.
Those aren’t the same and I’ve reworked a number of scripts to accomplish
the same result. So far most of them have worked if they are a bit clunky.
I did one where, instead of having the script pull the input parameters
once, do the calculation in a loop and have the script push the answer out
140 times, I had 140 separate calls to the script that did the calculation
once. That didn’t seem like the right way to go so I’ve been revisiting
what I know about Javascript.
When I stumbled into the routine that became what is below, I saw several
pieces of what I wanted to do. The script has no parameters as such, pulls
the input from one html element, does something with it, and pushes the
result out to two other html elements. That is ultimately what I want to
accomplish. That is what I haven’t mastered in TiddlyWiki. I don’t
understand why it doesn’t work.
This works in a conventional html web-page but I haven’t been able to make
it work in TiddlyWiki.If you play with this, you'll note that though you
clicked the button, the selected area of the textarea was still active,
even though the textarea did lose the focus.

[tw] Re: Javascript Interaction with a Textarea
Hi! Stephan's right. Once you click away, the textarea isn't the active element anymore. If the actual textarea is under your control, add the onchange handler to it or something.

[tw] Re: Javascript Interaction with a Textarea
This is normal HTML. In TW, you can't use the body tag and the script tag
can't be inside the html tags. Then there's problem with place and stuff,
so I suggest using the code of the function directly in the onclick handler
of the button, like this:
html
textarea rows=4 cols=50 id=myTextarea
342 Alvin Road
Houston, Texas
USA
Earth
Solar System/textarea
textarea rows=4 cols=50 id=myTextarea2
Nothing here/textarea
pClick the button to copy the highlighted content to myTextarea2./p
button type=button onclick=var txt =
document.getElementById('myTextarea'); var start = txt.selectionStart; var
finish = txt.selectionEnd; var sel = txt.value.substring(start, finish);
document.getElementById('myTextarea2').value = sel;
document.getElementById('demo').innerHTML = sel+' was extracted from
Textarea 1 and pushed into Textarea 2';Copy highlighted/button
p id=demoNothing yet/p
/html
This works in TWC.
