有時候咱們會碰到一些元素不可見,這個時候selenium就沒法對這些元素進行操做了。例如,下面的狀況:html
頁面主要經過「display:none」來控制整個下拉框不可見。這個時候若是直接操做這個下拉框,就會提示:java
from selenium import webdriver from selenium.webdriver.support.select import Select import os,time driver = webdriver.Chrome() file_path = 'file:///' + os.path.abspath('test.html') driver.get(file_path) sel = driver.find_element_by_tag_name('select') Select(sel).select_by_value('opel') time.sleep(2) driver.quit()
exceptions.ElementNotVisibleException: Message: element not visible: Element is not currently visible and may not be manipulatedweb
咱們須要經過javaScript修改display的值。chrome
js = 'document.querySelectorAll("select")[0].style.display="block";' driver.execute_script(js) sel = driver.find_element_by_tag_name('select') Select(sel).select_by_value('opel')
document.querySelectorAll("select")[0].style.display="block";ui
document.querySelectorAll("select") 選擇全部的select。spa
[0] 指定這一組標籤裏的第幾個。3d
style.display="block"; 修改樣式的display="block" ,表示可見。code
執行完這句js代碼後,就能夠正常操做下拉框了。htm
