Hi, I want pass a variable(which is not a instance variable) from controller to view in rails application, onclick I am going to controller and fetching data with ajax. Since the page is not reloaded I cant set the variable in cookies. So is there any way to pass a variable(which is not an instance variable) from controler to view? -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Adding @ to a variable doesn make the variable instance variable, its convention that are followed while writing a ruby program, I think... Here I have a variable x = 10, in my controller how can i access it in view without using cookies. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Why do you not want to do that? Colin -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Ya, thank you,adding @ to variable made it available in the view.
here, I m making HTTP request using ajax, which goes to my controller
and executes a method, Now I m getting return value in view. But I have
to display it in popup menu. the code for the pop up is
$.colorbox({html:"<%= @x %>",
width:"35%",height:"400px"});
But this value of @x is not displayed in pop up.

Assuming that the line of jquery code is executed client side and operates on
the HTML returned from the Ajax request you will not have access to the instance
variable. It will have been rendered in the returned HTML on the server. You
will either need to parse the value out of the HTML or just return json and
access it.
