Hello,
I tried the trunk version and again it almost works :)
1. the RequestVars aren't preserved for the ajax request. I think this can be
fixed by replacing in SHtml:692 the NFuncHolder with a call to
contextFuncBuilder, so the method would look like this:
def doit = makeFormElementWithName("submit", contextFuncBuilder(func), attrs:
_*){
case (funcName, elem) =>
elem %
new UnprefixedAttribute("value", Text(value), Null) %
("onclick" -> ("liftAjax.lift_uriSuffix = '"+funcName+"=_'; return
true;"))
}
I tested it on my example application
(http://github.com/adamw/lift-ajax-submit-test) and it works.
2. The button will work only with full ajax-forms right? So forms wrapped with
ajaxForm(...)? My initial use-case was for adding some ajax buttons to normal
forms (submitted with a normal http request), but I guess I can make the whole
form submitted with ajax.
Thanks!
Adam
