我正在尝试使用 Capybara 附加文件。输入元素是：

<input type="file" multiple="multiple" name="uploadfile[]" style="position: absolute; margin: 0px 0px 0px -175px; padding: 0px; width: 220px; height: 30px; font-size: 14px; opacity: 0; cursor: pointer; display: block; z-index: 2147483583; top: 3331px; left: 436px;">

附加文件的代码是：

attach_file 'uploadfile[]', '/home/user/image.jpg'

但它返回错误：

attach_file('locator', 'path/to/file.jpg', :visible => false )

应该做的伎俩。Capybara 默认忽略隐藏字段，你需要做的就是传入一个可见性选项

该:visible选项对我没有任何作用。似乎有一个:make_visible选项：

attach_file 'uploadfile[]', '/home/user/image.jpg', :make_visible => true

或者true使用自定义样式属性的哈希值，在尝试打开文件对话框之前将其设置为覆盖。

因为Ruby对页面加载不是很好，如果我是你，我会这样解决：

!30.times { if (driver.find_element(:xpath, "//input[@type='file']")rescue false) then break else sleep 1; end }

基本上，上面的代码将尝试 30 次（每 1 秒）来搜索您尝试附加的元素，如果该元素存在，则将退出循环。如果需要，您可以在 break 之后或 sleep 命令之后使用变量来指导您的流程。

祝你好运
