如何使用Ajax和Jquery在Rails 3中显示Flash错误消息？
|
我的控制器创建功能是
def create
@group = Group.new(params[:group])
@group.company=current_user.company
respond_to do |format|
if @group.save
format.html { redirect_to(@group, :notice => \'Group was successfully created.\') }
format.js
else
flash.now[:error]=@group.errors.full_messages
format.html { render :nothing => true }
format.js
end
end
end
$(\'<%= escape_javascript(render(:partial => @group))%>\').appendTo(\'#groups\');
$(\"#new_group\")[0].reset();

有了这个助手def flash_display response = \"\" flash.each do |name, msg| response = response + content_tag(:div, msg, :id => \"flash_#{name}\") end flash.discard response end<div id=\"flash\"> <% flash.each do |name, msg| %> <%= content_tag :div, msg, :id => \"flash_#{name}\" %> <% end %> </div>豹芜澈
在js.erb文件中为Flash设置一个JavaScript变量。然后检查一个值并使用javascript更新\“ flash-error \” div。它可能看起来像这样：$(\'<%= escape_javascript(render(:partial => @group))%>\').appendTo(\'#groups\'); $(\"#new_group\")[0].reset(); var flashError = \"<%=flash.now[:error]%>\"; if (flashError){ $(\".flash-error\").html(flashError); }
