javascript - 参数没有从使用javascript的提交表单中获取

Question

我有这样的 Controller

class HomesController < ApplicationController
  def index
  end

  def cheking
    @result = params[:type]

    respond_to do |format|
      format.js
    end
  end
end

并在 index.html.erb 上形成

<%= form_tag(checking_path, :remote => true, :format => :js, :method => :get)   do %>
    <%= select_tag "type", options_for_select([ "admin", "customer" ], "admin") %>
    <%= submit_tag "check now" %>
<% end %>
<div id="result"></div>

checking.js.erb 文件

$("#result").html("<%= escape_javascript(render("result")) %>");

我想把@result放在渲染文件_result.html.erb

<%= @result %>

但是当使用 admin 类型提交表单时，@result 不会出现在浏览器上。

日志:

Answer 1

在您的 checking.js.erb 中，您需要传递您的变量，以便您的部分可以访问它。你可以这样做:

$("#result").html("<%=j render partial: 'result', locals: {result: @result} %>");

并且在您的部分中您需要使用结果

#_result.html.erb
<%= result %>
