Hey all,

Normally you can use the :confirm functionality of link\_to\_remote to  
specify the text of a confirmation dialogue.

For example, :confirm =\> “hello” generate:  
\<a href="#" onclick="if (confirm(‘hello’)) { new Ajax.Request …

I’d like to replace “hello” with a JavaScript call (so that the  
confirmation dialogue can contain text based on what a user has so far  
done on the page. If I try to pre-emptively close the quote, it ends up  
just getting escaped, and the function name is simply displayed:

:confirm =\> “’+myFunction()”  
\<a href="#" onclick="if (confirm(’’+myFunction()’)) { new Ajax.Request  
…

Any idea how I might accomplish a dynamic confirmation dialogue?

Thanks!!  
-Jason

Have you tried :before instead of :confirm  
You’ll have to do your own confirm dialog but your function can  
build the confirm string any way you want
