[Laszlo-user] Hyperlink with onclick?

[P T Withington]

Well, David says it's not 'hyper' (it doesn't take you to another  
document), I say it's not 'link' (it's not a link to anything).  It  
creates an area of text that will send an event when clicked.  I  
appreciate this is nifty new functionality, I'm just asking that we  
step back a minute and think about the best UI and how to name and  
document it, so we don't regret it down the road.

The message that started this thread was trying to say (something like):

<a href="javascript:...">...</a>

The other way of saying this in html would be something like:

<span onclick="...">...</span>

Both of those take out the intermediate step that the current  
interface has, where you have to assign an ID to the active text and  
then you have to dispatch from the text click event based on ID to the  
action you want.  I wonder if we want this ID mechanism exposed, or if  
we want a higher-level interface?
