Question

我希望在按下按钮时，将AJAX调用发送到我的events_controller#check操作。这是我的代码：

事件\ new.html.erb ：

<button id="check-button" type="button">Check</button>

的application.js：

$(document).on('click', "#check-button", function(){
    var checkList = []; //creates array to store customer ids
    ...
    });

    $.ajax({
            url: '/events/check',
            data:checkList
        }
    )

});

events_controller＃检查

def check
    checkList = params[:checkList]
    ...
end

的routes.rb

post 'events_controller/check' => 'events#check'

我在控制台上点击按钮时出现此错误：

Started GET "/events/check?undefined=" for 127.0.0.1 at 2016-02-03 11:36:33 +0000

...etc

为什么要尝试找到'show'而不是'check'？我该如何解决？感谢

Answer 1

2个问题：

你的可能在你宣布的路线之前得到show（为什么会去POST）

您尚未调用#config/routes.rb resources :events do post :check, on: :collection #-> url.com/events/check end #app/assets/javascripts/application.js $(document).on('click', "#check-button", function(){ var checkList = []; //creates array to store customer ids ... $.ajax({ url: '/events/check', data: checkList, method: "POST" }); });方法

您应该拥有以下内容：

<ul> 
    <li><a href="#c1">Tab 1</a></li> 
    <li><a href="#c2">Tab 2</a></li>
    <li><a href="#c3">Tab 3</a></li>
    <li><a href="#c4">Tab 4</a></li>
</ul>

<div id="c1">CONTENT TAB 1</div>
<div id="c2">CONTENT TAB 2</div>
<div id="c3">CONTENT TAB 3</div>
<div id="c4">CONTENT TAB 4</div>

Answer 2

在我看来，如果请求中缺少类型，则需要发布请求，因此它会将GET请求作为默认请求方法。

您需要将type添加到您的ajax：

type:'post',

Answer 3

1检查您的页面中是否正确导入了Jquery文件。

module RSpecMixin
 include Rack::Test::Methods
 def app() Sinatra::Application end
end

RSpec.configure do |config| 
  config.include RSpecMixin 
end

检查您应用的网址值是否正确。然后使用下面的代码。

AJAX调用无法正常工作，寻找错误的操作？
