如何從隱藏的選擇列表中選擇一個值？

Question

我想從this website中選擇隱藏的選擇列表，然後選擇選項0 - 0,5。我不斷收到(Selenium::WebDriver::Error::ElementNotVisibleError)。

     from aegon.rb:15:in `<main>' 

這是選擇列表中的HTML是什麼樣子：

<select name="werkervaring" class="selectBox" style="display: none;"> 
    <option value="">Geen voorkeur</option> 
    <option value="1">0 - 0,5</option> 
    <option value="2">0,5 - 1</option> 
    <option value="3">1 - 2</option> 
    <option value="4">2 - 5</option> 
    <option value="5">5 - 10</option> 
    <option value="6">&gt; 10</option> 
</select> 

注意style="display: none;"是我不斷收到錯誤的原因。

下面是我使用的代碼：

require 'watir' 

b = Watir::Browser.new :phantomjs 
b.goto('https://werkenbijaegon.nl/vacatures/?utm_source=aegon.nl&utm_medium=link&utm_content=home&utm_campaign=werkenbij') 

b.select_list(:name => 'werkervaring').select '0 - 0,5' 

b.close 

的問題是我怎麼能選擇一個隱藏的選擇列表中選擇0 - 0,5？我應該用別的東西代替Watir嗎？

Answer 1

右側的選擇列表之後有一個鏈接，並在鏈接select_list中的向下箭頭。點擊箭頭後，有uls和lis。有一個你正在尋找的價值。有一個鏈接。點擊它。

b.select_list(:name, 'werkervaring').parent.link.click 
b.li(text: '0 - 0,5').link.click 

注意事項，以確保我們使用正確的名單，我還是習慣werkervaring作爲一個獨特的定位，然後發現了同樣的父下的兄弟姐妹鏈接。

Answer 2

Selenium只允許用戶可以實現的交互，因此不允許與隱藏列表進行交互。

如果列表出現某個操作（例如，鼠標懸停），則需要先執行該操作。如果列表通過另一個對象（例如select2）顯示，那麼您必須通過該元素進行交互。然而，如果你真的想在不遵循這一點的情況下實現這一點，那麼你可以通過selenium執行JavaScript來啓用或設置它。

的優點，如果測試這種方式雖然商榷

Answer 3

b.select_lists[2].select "0 - 0,5"
