[Richard B. <ric...@sk...>]

Hi, I didn't receive the original of this message, so I reply to this reply.
I needed the same functionality, and came up with this solution:

Remember, we are trying to use a link like this:

<a href="http://www.cnn.com" onclick=alert("hi");return false;>click</a>

This would normally only show the alert, as the navigation has been
cancelled by the "return false".
This doesn't work in DynAPI however.

So, in mouse.js I added this:
browserReturn = true

at line 33 just after "DynMouseEvent.forceMouseUp = false"

and changed line 64 from "evt.browserReturn=true" to

evt.browserReturn=browserReturn;

Now in links  where you want to cancel the default navigation you do this:

<a href="http://www.cnn.com"
onclick=alert("hi");browserReturn=false;>click</a>

And it works the same as "return false" would. All other links keep normal
behavior.
Note that you now no longer need to use "javascript:void(0)" it will work
fine like this:

<a href="" onclick=alert("hi");browserReturn=false;>click</a>

This has not been thoroughly tested yet, so I'm not sure if this is the best
solution, or if this should be in CVS or not...

BTW, I'm also going to be making a backwards-compatible (readable in
browsers without javascript, or javascript version 1.0) dynapi page soon, so
any tips you (Ernest  or others) have would be appreciated.

Cheers,
Richard Bennett
