Receiving return responses from code inside a html form

[skye riquelme]

Hi All

Trying to understand more about javascript in TiddlyWiki and Html forms.

I gave a script that I use so people can login to a TW page (on-line). Now the script responds with various messages (using the javascript "return" command) and all works well when the script is in a seperate tiddler (obviously I have InlineJavascriptPlugin installed!!).

Now if I put that script inside a html form (which collects the users login details), the script is processed when the user hits the "button" (<input type=button...)... but the return messages are not seen! Why not?

And is there some way I can get to see those messages...as the user needs the confirmation ("logged in"..."login failed"...that the javascript is generating.)

Thanks in Advance
Skye

The ability to render the return value from script is a feature of
InlineJavascriptPlugin and is not supported by embedded javascript
handlers invoked from standard HTML.

For your purposes, you might try using: alert('message text here').
This will display a browser-based popup message box with your text and
an OK button.

If you really need to render the output following the form, that is a
bit more tricky. You'll need to create a new containing element at
the end of the form, and then wikify() your message into it, like
this:

<input type="button" value="go" onclick="
var out=this.form.insertBefore(document.createElement('div'));
wikify('message text',out);
">

enjoy,
