hi guys, I am now rewriting an existing app (rails 2.3.8) with rails 3.1.x.
As observe_field() is no longer the way to go with rails 3 when ajax is used, I am trying to rewrite a piece of functionality for when a select box (drop down) with a div id of 'category' is clicked (onChange), -a call is made to the sub_categories controller with the category ID (from the selected option in the category select box) -the sub categories belonging to the selected category ID will be returned and a another select box is to be generated in the div with id of 'sub_category'. I'm looking at http://www.simonecarletti.com/blog/2010/06/unobtrusive-javascript-in-rails-3/ and I have a question now. How do I go about passing a variable value to the javascript that performs the asynchronous call? For example, i have : // Append the function to the "document ready" chain jQuery(function($) { // when the #search field changes $("#category").change(function() { // make a POST call and replace the content $.post(<%= category_sub_categories_path %>, function(data) { $("#results").html(data); }); }); }) -how do I pass the category id (which is a form value) to the category_sub_categories_path?? -would the category_id value be valid in the jQuery call? -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
