I have the following code in the controller. I am populating a drop down box dynamically based on the selection from another drop down box.
def update_releases project = Project.find(params[:project_id]) releases = project.releases puts "releases==#{releases}" render :update do |page| page.replace_html 'releases', :partial => 'releases', :object => releases end view code:
-form_tag reports_path(report_type=1),:method => :get, :multipart => true ,:id => "filter" do %table.grid.full %tr %td.grid.full_panels{:style => "width: 20%"} Project: %td.grid.full_panels{:style => "width: 20%"} //= select_tag "projects",options_from_collection_for_select(projects,"id","name",params[:projects]), {:onchange => "#{remote_function(:url => {:action => "update_releases"},:with => "'project_id='+value")}"} = select_tag "projects",options_from_collection_for_select(projects,"id","name",params[:projects]), :class => "update_releases" %td.grid.full_panels{:style => "width: 20%"} Releases: %td.grid.full_panels{:style => "width: 20%"} <div id="releases"> = render :partial => 'releases', :object => @releases %td.grid.full_panels{:style => "width: 20%"} Cycles: %td.grid.full_panels{:style => "width: 20%"} <div id="cycles"> = render :partial => 'cycles', :object => @cycles %tr %td.grid.full_panels{:style => "width: 20%"} %td.grid.full_panels{:style => "width: 20%"} %td.grid.full_panels{:style => "width: 20%"} =submit_tag "Submit" = javascript_include_tag "pages/ic" partials code : = select_tag "releases",options_from_collection_for_select(releases,"id","name",params[:releases])
Jquery: //change the releases drop down based on the selction of the projects drop down.
$('.update_releases').live("change", function() { $.ajaxSetup({beforeSend: function(xhr) {xhr.setRequestHeader("X- CSRF-Token", $("meta[name='csrf-token']").attr("content")); }}); var project_id=($(this).val()); $.post('/reports/update_releases', {project_id: project_id}); return false; }) I am getting an error element doesn't support this property" as a pop up on chaning the selection in the drop down box. Please help me out here.
