有时候咱们会碰到一些元素不可见,这个时候selenium就没法对这些元素进行操做了。例如,下面的状况:html
页面主要经过“display:none”来控制整个下拉框不可见。这个时候若是直接操做这个下拉框,就会提示: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
咱们须要经过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") 选择全部的select。spa
[0] 指定这一组标签里的第几个。3d
style.display="block"; 修改样式的display="block" ,表示可见。code
执行完这句js代码后,就能够正常操做下拉框了。htm
