Problem with jQuery in rails

How create a link_to_remote in a jQuery script where url need a parameter that is a javascript variable.

I need create a link开发者_开发技巧_to_remote in pure jQuery.

Thanks in advance

You'll want to use the :with parameter with link_to_remote:

link_to_remote( args[:title], 
                    :update => args[:update],
                    :url => { :action => args[:action], 
                      :id => id, 
                      :starting => args[:starting] 
                    },
                    :with => "'filter[viewer_id]=' + $('filter_viewer_id').value",
                    :loading => "Element.hide('#{args[:update]}');Element.show('#{args[:loading]}')",
                    :complete => "Element.show('#{args[:update]}');Element.hide('#{args[:loading]}')" )

Notice how I am sending the filter_viewer_id by getting it's value from a form field with jQuery. If you don't need that level of detail, just pass the name of your javascript variable.

Like this:

<%= link_to_remote('Hello', :url => "/test?id='+ id +'&test=true") %>

This will result in:

# => <a href="#" onclick="jQuery.ajax({data:'authenticity_token=' + encodeURIComponent('++FcXPJ0/jfp/IO6sgaEPxMfzOr+vkT5zrGVMMSkJVE='), dataType:'script', type:'post', url:'/test?id='+ id +'&amp;test=true'}); return false;">Hello</a>

Very little info on your post. Are you using Rails 3? If so, did you check the jquery-rails gem out?
