Hi i am using prototype.js in my rails app via observe_field and RJS.
For the most part it works except when I attempted to update some HTML
elements at the end. On the controller side, I am using the following
bit of code
render :update do |page|
page.replace_html ''field2'', h(field2)
page.replace_html ''field3'', h(field3)
page.replace_html ''field4'', h(field4)
end
In IE7, I got a Javascript error dialog box "rjs error: [object
Error]". I also got a follow-on error dialog box showing all 3
elements "Element.update("field2", "value...");
Element.update("field3", "value...");
Element.update("field4",
"value...");" Alas but field4 never got updated, and field3 has
both
field3 and field4 values. Can anyone help? Thanks in advance for your
help.

Digging in further, this appears to be a bug with prototype.js for html input element type. If I switch field4 to textarea type, it works fine, anyone came across this problem?

Thanks Ken. Is there an easy way to do that in rails? I assume that the syntax is page.replace_html but perhaps not On Jul 9, 10:16 am, Ken Snyder <kendsny...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> bngu wrote: > > Digging in further, this appears to be a bug with prototype.js for > > html input element type.

Sounds like this could be an enhancement request: have Ajax.Update detect if the passed element is an input, and if so, update the value rather than the innerHTML. Does a core dev want to sound off on whether a patch to that effect would be implemented? TAG On Jul 9, 2007, at 12:39 PM, bngu wrote:> > Thanks Ken. Is there an easy way to do that in rails?

After some more digging, I found a way the syntax to changing the value of an input element in Rails RJS. Instead of using page.replace_html, I have to do it like this page[:field_id].value = .... This is cool stuff, but it does mean that you need to understand prototype.js functions which is technically part of Rails. Thanks everyone.
