将实例变量传递给js.erb文件（Rails 3 / jQuery）

Question

I have an "index.html.erb" file with the following:

<%= render @users %>

This renders "_user.html.erb" and outputs a button for performing a certain action on each user:

<%= link_to "action", action_path(user), :id => "#{user.id}_action", :remote => true) %>

I've set up my User controller to respond to the AJAX request by looking at "action.js.erb".

In order to perform javascript methods on particular users within the partial, and I'd like to know how instance variables from my partial (such as user.id) can be passed into or accessed within the js.erb file, for instance:

$("#{@user.id}_action").toggle();

Answer 1

你访问你的信息*.js.erb -files就像在你的*.html.erb -files，使用@users或控制器中声明的其他实例变量：

$("#<%= @user.id %>_action").toggle();
