互動我試圖附加文件使用水豚。輸入元素是：附加文件與水豚 - 元素目前不可見，>因此可能不會與

<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;">

代碼附加文件是：

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

但它會返回錯誤：

如何解決這個問題？

嗨伊萬，我不認爲你的代碼有什麼問題。可能該頁面尚未完全加載，並且您嘗試過早地抓住元素。理想情況下，您應該在嘗試附加之前引入延遲。 – 2013-02-28 15:31:49

-3

因爲Ruby是不是很好的頁面加載，如果我是你，我會解決這個問題是這樣的：

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

基本上上面的代碼將嘗試30次（每1秒）來搜索如果元素存在，則試圖附加的元素將退出循環。如果需要，可以在休息之後或睡眠命令之後使用變量來指導流程。

祝您好運

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

的應該做的伎倆。水豚默認忽略隱藏的領域，所有你需要做的就是通過一個可見性選項

:visible選項對我沒有任何幫助。這裏似乎是一個:make_visible選項：

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

或代替true與將它設置試圖打開文件對話框之前覆蓋自定義樣式屬性的哈希值。
