Question

我需要读取名为＆＃34; data-contents＆＃34;的属性的值。来自特定页面中的所有跨度

<span tabindex="0" title="" class="text-warning  ng-isolate-scope" role="button" data-original-title="" data-toggle="popover" data-placement="top" data-html="true" data-contents="If you are not sure which type of occupation in the list to choose, please call us on (852) 2884 8888 and we'll be happy to help you." data-content="If you are not sure which type of occupation in the list to choose, please call us on (852) 2884 8888 and we'll be happy to help you." data-da-popover="" data-da-popover-id="daPopover1455178167018" data-container="body" data-trigger="focus"><img src="/app/ui/images/question-icon.png">          </span>

我写了以下代码，

  b.spans.each do |span|
        puts span.data-contents
  end

但它抛出了这个错误＆＃39 ;:未定义的局部变量或方法`内容＆＃39; for main：Object（NameError）＆＃39;

有人可以帮助我阅读这些数据内容的价值吗？

Answer 1

您可以像其他属性一样获取数据和咏叹调属性。唯一的区别是方法名称使用下划线而不是破折号。

要获取data-contents属性，您可以执行以下操作：

puts span.data_contents

如何从带有watir的跨度读取＆＃34;数据内容＆＃34; -attributes的值？
