單擊在Python中使用Selenium的隱藏鏈接

我在Python中使用Selenium嘗試單擊鼠標懸停在該下拉菜單上時出現的下拉菜單中的鏈接。這裏是下拉菜單信息：單擊在Python中使用Selenium的隱藏鏈接

<div id="DownloadMenu"> 
    <ul id="DownloadMenu_control" class="topmenu" widgetid="DownloadMenu_control"> 
    <li class="horizontal-list-item-2 leftFloatedItem" id="[email protected]_1" widgetid="[email protected]_1" style=""> 
    <a class="horizontal-list-item-2 leftFloatedItem" href="javascript:void(0)">Download</a> 
    <ul id="common_navigation_MenuControl_6" class="submenu" style="display: none; left: 0px; visibility: hidden;" widgetid="common_navigation_MenuControl_6"> 
    <li class="subitems" id="[email protected]" widgetid="[email protected]"> 
    <a href="javascript:com.reuters.rts.event(event, 'openMultiDocInfoViewerBatchViewEikon', 'itemsCollectionId', 'AllDocumentListView_items', 'researchTableManagerId', 'AllDocumentListView', 'summary', escape(encodeURIComponent(dijit.byId('advancedSearchManager').getFilterSubmittedSummary())), 'fileSizeLimitForMerging', '25','forBatchPrint','true', 'action','Save');">Documents</a> 
    </li> 
    </ul> 
    </li> 
    </ul> 
</div>

我想單擊「a href」標記中的「文檔」鏈接。當我將鼠標懸停在菜單上時，代碼更改如下：

<div id="DownloadMenu"> 
    <ul id="DownloadMenu_control" class="topmenu" widgetid="DownloadMenu_control"> 
    <li class="topitemOn" id="[email protected]_1" widgetid="[email protected]_1" style=""> 
    <a class="horizontal-list-item-2 leftFloatedItem" href="javascript:void(0)">Download</a> 
    <ul id="common_navigation_MenuControl_6" class="submenu" style="display: none; left: 0px;" widgetid="common_navigation_MenuControl_6"> 
    <li class="subitems" id="[email protected]" widgetid="[email protected]"> 
    <a href="javascript:com.reuters.rts.event(event, 'openMultiDocInfoViewerBatchViewEikon', 'itemsCollectionId', 'AllDocumentListView_items', 'researchTableManagerId', 'AllDocumentListView', 'summary', escape(encodeURIComponent(dijit.byId('advancedSearchManager').getFilterSubmittedSummary())), 'fileSizeLimitForMerging', '25','forBatchPrint','true', 'action','Save');">Documents</a> 
    </li> 
    </ul> 
    </li> 
    </ul> 
</div>

您可以看到visible：hidden部分在第二個ul標籤中消失。

我發現使用下面的代碼頁面上的元素：

download_menu = driver.find_element_by_id("DownloadMenu") 
download_button = download_menu.find_elements_by_tag_name('a')[1]

如果我嘗試使用點擊下載按鈕：

download_button.click()

我得到一個錯誤，該元素是不可見：

ElementNotVisibleException: Message: element not visible

所以，我想，

ActionChains(driver).move_to_element(download_menu).move_to_element(download_button).click(download_button).perform()

當我這樣做時，沒有任何反應。所以，我想執行腳本，以使菜單可見，然後點擊並沒有工作之一：

visibility_tag = download_menu.find_elements_by_tag_name('ul')[1] 
driver.execute_script("arguments[0].style.display = 'block'; arguments[0].style.left = '0px'; arguments[0].style.visibility = ''", visibility_tag)

當我運行execute_script功能，菜單將不會在我的瀏覽器變得可見。它仍然不能被點擊。我在這裏瘋了。有任何想法嗎？我在Python中使用了Selenium的Chrome擴展。

如果使用類似CSS任何iframe.try見：「#DownloadMenu一個[HREF * =文件] 「 – lauda

你應該嘗試使用ExplicitWaits等到Documents鏈接可見，使以如下點擊： -

from selenium import webdriver 
from selenium.webdriver.common.by import By 
from selenium.webdriver.support.ui import WebDriverWait 
from selenium.webdriver.support import expected_conditions as EC 

wait = WebDriverWait(driver, 10) 

download_menu = driver.find_element_by_id("DownloadMenu") 

action = ActionChains(driver) 
#hover on download_menu first 
action.move_to_element(download_menu).perform() 

#now find Documents link and click 
documents = wait.until(EC.element_to_be_clickable((By.LINK_TEXT, "Documents"))) 
documents.click()
