Question

Right now I can call a method using ajax (:remote=> ‘true’) at awisprotect_path by simply clicking on the “x” in this link

<%= link_to "x", 
    awisprotect_path,
  :remote => true,
  :method => :post,
  %>

The controller action renders jquery so the response is included into the html in the view

<div class="awishanswer">

</div>

That’s all working fine. However, instead of having an “x” to click, I wanted the user to click a button and get the same result. So I essentially just wanted to put the link info

<%= link_to "x", 
    awisprotect_path,
  :remote => true,
  :method => :post,
  %> 

into this button

 <button class="btn small primary" >
                    check
</button>

So I created this form and put it in a partial

<%= form_tag(:controller => "sessions", :action => "awisprotect", :remote => true, :method => "post") do %>


 <button type="submit" class="btn small secondary">check awis</button>

 <% end %>

but the problem is that the controller action that renders js is not putting the result of the action into the html div. Instead, it’s redirecting to a blank page and then printing the jquery method with the result that I was checking for with the controller action. the blank page just shows this…

$('div.awishanswer').html(' html to be inserted in div');

Can anyone explain?

In the url it says

http://localhost:3000/awisprotect?method=post&remote=true

Answer 1

in the view file

<div class="awishanswer" id="awishanswer">
    <% form_remote_tag :url => {:controller => "sessions", :action => "awisprotect"}, 
                    :html => {:method => "post"}, :update => "awishanswer" do %>
        <input type="submit" class="btn small primary" value="check" />
    <% end %>
</div>

in the action

def awisprotect
    @flag = params[:flag] // suppose sending parameter flag from form
   // do something
   render :partial => 'partial file containing html to send to view'
end

1. The form will be submitted when the submit button is clicked.
2. the action will send the html contained in partial file.
3. the form will update the div with id provided in form with the html code send back from action.

EDIT:partial file

<%if @flag%>
// include some html
<%else%>
// include some other html
<%end%>
