You’ll need to make an ajax request. You should be able to draw some
inspiration from the remote_function rails helper (which will
generate the right bit of js that you can then reuse).

Hey there guys! Still having problems with javascript with Rails! Heres
my problem simplified (btw I know it doesn’t work! >_< ):

<%= @localVariable = javascript_tag (“hello(‘hi serkan!’)” %>
<%= javascript_tag(remote_function(:update => :ajax_call,
:url => { :controller => ‘login’,
:action => :get_string },
:with => “'InputVariable=” + @localVariable + “’”)) %>

So Im trying to get some data from a javascript function into rails, but
I just cant figure it out. Any help would save me from killing myself
and would be gratefully appreciated!

thanks!

:onchange=>remote_function(:url =>{:action => ‘Yr_action’},:with =>
“‘id=’+this.value”, :method=>:post)

with this logic u can carry out things…

:with is to pass the value to rails method using java script…
this patch i used in select tag so in ;with is used this.value u change
as per yr need.

with :action u can call a rails method in yr controller…

Thanks for replying Ratnavel! You’re a stud!!

:onchange=>remote_function(:url =>{:action => ‘Yr_action’},:with =>
“‘id=’+this.value”, :method=>:post)

One question! Instead of using a form element e.g."‘id=’+this.value",
can i do this:

:onchange=>remote_function(:url =>{:action => ‘Yr_action’},:with =>
“‘id=’+name”, :method=>:post)

thanks again!

The reason why you’re not getting a reply is because people ignore short
replies like “no luck… im still stuck :-(”.

Explain how you’re stuck, what exactly you’re trying to accomplish in
just
the right amount of detail.
