Re: [Xsltforms-support] Calling Javascript-defined functions from XForms.

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Hello,

I'm trying to use the load element with a javascript function, to do 
things like changing the page title or the anchor dynamically, and 
there's some strange problems. I managed to do it with the setvalue 
element though, but I don't know if it's a correct way to do it with 
xforms or if it's just working with Xsltforms.

Here is the code :

With Test 2 in think the new namespace for javascript is not recognized 
and Test 3 load the script but then tries to load the page « Hello World 
! ». With Test 4 there's a XSLTForms Exception : « instance is not 
defined ».
