help getting started with javascript generated forms
How does one generate a form within a view using javascript?
Specifically, assume views/premise/new.html.erb looks like this:
<%= form_for(Premise.new) do |f| %>
<%= f.hidden_field :full_address, :value => $FULL_ADDRESS %>
<%= f.hidden_field :geocoding, :value => $GEOCODING %>
<%= f.submit :value => "use this address" %>
<%= f.label

Using onSubmit tag in form_tag?
Hi guys,
I have been working on a form that would use javascript to validate the
data before submitting it, and from my view.rhtml I have a statement
like this:

Getting value of form using Ajax (and problems with Safari)
I have got two forms, the first is a textarea plus a link that activates
some javascript to change the form, the second activates some javascript
on the onchange event which changes it into a textarea form.
This works in Firefox, but not in Safari.
Also, I need the value which is selected. I''ve found an example that
gives the parameter to the javascript, like this:

form_for() and name
how can i give name attributes for form_for(), so it will give an output
like <form name="f">. it is because that i need to access the form name
for javascript manipulation.
as far as i know, name can only used in form_tag(), but i currently have
more than 50 forms that built using form_for(). the structure is like
this:
<% form_for symbol, item,

how to give a form a name
Using a <%= form_tag ... %>, how do I give a form a name, so that I can
reference it with javascript? I sure can''t figure this out from the docs...
Thanks,
Shelby
PS - what I am trying to do is just have the focus in the first form field
when the form is loaded. There has to be an easy way to do this, but I
can''t figure it out...

form_tag vs form_remote_tag ----- the :condition option
form_remote_tag has a really useful little thingamob called
:condition. you give it a string which is then interpolated into the
form tag in such a way that the form is only submitted if :condition
evaluates in javascript to true.
so the logical thing to do is give it a JavaScript function
<%= form_remote_tag ( :condition => ''your_function_here()'',

link_to, image_submit_tag, "changes only with POST" and "usability without Javascript" question
Hello,

AJAX)
If I use "GET should be safe" option (verify) and link_to

observe_form without ajax?
This betrays my lack of javascript knowledge, but is it possible to
watch a whole form for changes and activate some javascript when those
changes occur without any remote request?
That is, I want to do exactly what observe_form does, but without the
ajax call actually happening. I realize I could use the form_tag
:onchange parameter, but that seems to be incapable of doing things like

Hi,
I am new to rails and I have setup Typo on my site. One little
thing bugs me, the login page doesn''t give focus to the "user_login"
field. I was wondering what do I need to do to make rails help with
this? I have seen some simple inline javascript to set the focus,
sort of like:
document.<form_name>.user_login.focus()
However the rails view doesn''t
