Thanks, I focused too much on the XML syntax.
session.flash=DIV('Item deleted. ',A('(undo)',_href=URL('undo_func')))
works and renders to html with a hyperlink.
However,
session.flash=XML('<a href="%s">click me</a>' % URL('index'))
still renders to a string instead of html, feels like unexpected behavior
to me.
To allow hyperlinks in the flash message, it would suffice to bind to the
flash DIV the jQuery "dblclick" event instead of "click". So line 28 of
web2py_ajax.js would look like:
jQuery('.flash').dblclick(function(e) { jQuery(this).fadeOut('slow'); e.
preventDefault(); });
I'll leave it to the elders of web2py to decide whether this breaks
backward compatibility.
Maybe a close/dismiss/OK button on the flash would also be a good or better
solution.
I think it would be a nice feature to allow for working hyperlinks in the
flash.
Thanks for the input!
