Re: [Rails] Ajax - the Rails way!

2013/5/30 Tommy Ng <lists@ruby-forum.com>

<% form_tag({:controller => "main", :action => "contact"}, :remote =>

There should be an equal sign (=) just after the percent to tell erb, that it should output something

 

true, :update => "result") do %>
   Name:<br/><%= text_field_tag(:name, :"", :id => "name") %><br/><br/>
   Message:<br/><%= text_area_tag(:message, :"", :id => "message")
%><br/>
   <%= submit_tag "Send" %>
<% end %>
<div id="result"></div>

First problem, my form now disappeared.  It appeared when it was 

<%= form_tag("/main/contact", :method => "post", :id => "contactForm")
do %>

Here you have that equal sign, so erb knows to output the formtag, in the line without it, the returnvalue of form_tag is just ommited.

 

Also there are some nice railscasts about Ajax and a blogpost wich kickstarted me a few weeks ago: http://www.alfajango.com/blog/rails-3-remote-links-and-forms/
