Hello,
I currently have in my ''view/rhtml page'' a link_to, as
follows:
<% link_to_remote "run", :before => "new
Effect.Shake(''myform'')", :url
=> {:action => ''execute'', :id => @input } %>
This calls a method ''execute'' in my controller.
''execute'' runs a loop.
OK, i would like to be able to update the rhtml page from within this
method in my controller. How do i do this?
For exmaple, the loop would just alter a variable and update a div in
the web page.

Although, I think the code in the rjs file is executed as sson as the corresponding method in the controller is called, right? I would like to be able to loop in the controller, and if some condition is true - then execute the javascript and update the page. Going into my problem more specifically, what i am doing is trying to get input from the user. So, when the user clicks the button on the webpage i would, method ''execute'' is called in the controller, which runs a loop. When some condition in this loop is true, i then want to execute some javascript, which will toggle a textfield into view (or display a prompt), allow the user to input a string, and when confirmed (OK clicked), feed ths string back into a variable in my loop. Do you think this would be possible? Thanks again. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
