hello im anas .. im capable of using link_to_remote but i don't know how to use form_remote_tag.. plzz any one help me in details of using this one with examples
thanking u
mohd anas
form_remote_tag returns you a form tag that will submit your form using XMLHttpRequest in the background instead of the regular/normal POST
a small example
in your view
{ :controller => 'order', :action => :add_to_basket, :id =>"new_line_item"},
:loading => "Element.show('XXXXX')",
:complete => "Element.hide('XXXXX')" -%>
[-- your form content --]
you can access your post variables as usual in your controller
mohd,
form_remote_tag is used almost identically to form_tag, it will just post using AJAX, and will not refresh the screen. You do have some additional parameters for javascript that would not have with form_tag.
Kevin Elliott "WeLikeFood Beta":http://www.welikefood.com Great restaurants. Great reviews.
Balaji provides a nice example. One small thing though. I think 'end_form_tag' has been deprecated in favor of a block. So:
{ :controller => ‘order’, :action => :add_to_basket, :id =>â€new_line_itemâ€}, :loading => “Element.show(‘XXXXX’)â€, :complete => “Element.hide(‘XXXXX’)†do -%>
...
and on that note, there is no reason why you might not also consider using form_remote_for instead of form_remote_tag, if you want to submit this form to update a model then really form_remote_for might be preferable. You might see something like:
add_to_basket_order_path(@order) do |form| %> etc etc etc
i point that out not to say to use one or another, but this lets you deal specifically with a model, so something to keep in mind.
Hi .. Make sure that you have included the jacascript tag prototype
The code for view goes here { :action => 'report_inapropriate'} ,:html => { :id =>"my_form1" }do |f| %> 35,:rows=>5%>
the code for controller goes here
if request.post?
@reported_video= ReportedVideo.new(params[:reported_video])
if @reported_video.save
# this is how you can control the page elements, by giving then different effects
# for more effects pls refer to the rjs cheat sheet!!
render :update do |page|#rjs for posting comment and replacing the element
@video=Video.find_by_id(@reported_video.video_id)
page['my_form1'].reset
flash[:notice] = "The video is been reported"
page.replace_html :message, flash[:notice]
flash.discard
page.visual_effect(:fade, 'report', :duration => 0.5)
page.visual_effect :highlight, 'message', :duration => 2
end #end for rjs
end
end
more ever you can use the submit_to_remote tag this is how its shown... the view code goes here
{ :action => 'calculate_shipping' ,:controller=>'shop'},:loading
=> "Element.show('calculating');",:complete => "Element.hide('calculating');" ,:class=>"calculate_shipping"%>
The code for the controller will be as shown...
Best of Luck Thanks and regards Saurabh Purnaye http://saurabh.purnaye.googlepages.com
