我试图用vanilla JS(没有jQuery)编写一个脚本,如果有人点击这个元素之外,它将从页面中删除一个元素.

但是,它div有许多嵌套元素,我设置的方式是,即使单击第一个元素内的元素,它也会消失.

示例标记:

<div id='parent-node'>
  This is the Master Parent node
  <div id ='not-parent-node'>
     Not Parent Node
    <button>Button</button>
    <div id='grandchild-node'>
      Grandbaby Node
    </div>
  </div>
</div> 

所以我想,无论元素嵌套有多深,它都会检查它是否是<div id='parent-node'>元素的后代.因此,如果我点击它,它将不会删除父节点及其所有后代.该div和它的后代应该只点击父母之外时,可以动态删除div.

目前这就是我所拥有的,而且我知道我写的内容存在一些严重的谬误:

function remove(id) {
    return (elem = document.getElementById(id)).parentNode.removeChild(elem);
}

document.addEventListener("click", function (e) {
    remove('parent-node');
});

我正在尝试设置selenium webdriver与Browserstack一起使用Java进行自动化测试.我安装了Selenium for java,我从browserstack的网站https://www.browserstack.com/automate/java#configure-capabilities复制并粘贴了代码,以建立一个示例自动化测试.

我javac -classpath selenium-server-standalone-2.48.2.jar JavaSample.java从终端运行(JavaSample.java是带有selenium配置代码和示例测试的文件),我收到以下错误:

JavaSample.java:1: error: package org.openqa.selenium does not exist

                      ^

我试图'reset_password_token is invalid'完全覆盖Devise的错误消息.我想看看"password reset link has already been used."我怎么能这样做？没有看到这个字段或关键字devise.en.yml.

我目前正在尝试在终端中运行我的测试套件,但是我收到以下错误:

Missing required arguments: aws_access_key_id, aws_secret_access_key (ArgumentError)

我在我的项目中使用Carrierwave,我很确定这是导致问题的原因.这是我的config/initializers/carrierwave.rb:

CarrierWave.configure do |config|
  config.fog_credentials = {
    :provider               => 'AWS',                       
    :aws_access_key_id      => ENV['S3_ACCESS_KEY_ID'],                        
    :aws_secret_access_key  => ENV['S3_SECRET_ACCESS_KEY']
  }
  config.fog_directory  = 'my_directory'                    

end

这是我的日志:

我制作了一个非常简单的 RESTful 应用程序，当我在表单字段中输入一个字符串并提交时，数据库保存 NULL 而不是输入字符串。

这是我的控制器：

def create
  @song = Song.create(params[:title])
  flash[:success] = "You have successfully created a new project!"
  redirect_to "/songs/#{@song.id}"
end

这是我在 new.html.erb 文件中的表单：

<%= form_for(@song) do |f| %>

<div class="field">
  <%= f.label :title %><br>
  <%= f.text_field :title %>
</div>

<div class="actions">
  <%= f.submit %>
</div>

<br>

<% end %>

我试图用JavaScript编写一个快速的Selenium Webdriver.

我有它设置:

var webdriver = require('selenium-webdriver');

var driver = new webdriver.Builder()
   .withCapabilities(webdriver.Capabilities.chrome())
   .build();

我已经安装了selenium-webdriver.我认为问题来自Grunt.我已经到处寻找答案了,但我还没有找到合适的解决方案.

有任何想法吗？

我正在编写 Rspec 测试，但它们失败了，因为 Mysql 无法识别individual字段列表中的列。

individual当我查看内部时，该列确实存在于数据库中。

schema.rb将其列在正确的表中，attr_accessible并在 ruby​​ 模型中提及。

这是错误日志：
