python selenium 报错unknown error: cannot focus element 解决办法
登录框由于js限制,定位到元素后无法sendkey ,sendky报错如下:
selenium.common.exceptions.WebDriverException: Message: unknown error: cannot focus element
(Session info: chrome=67.0.3396.87)
(Driver info: chromedriver=2.40.565498 (ea082db3280dd6843ebfb08a625e3eb905c4f5ab),platform=Windows NT 6.1.7601 SP1 x86_64)
但是这个手工是可以输入的,应该用自动化的手段也能输入。解决办法就是是使用selenium 的ActionChains。并结合driver.execute_script使用。完整可执行示例代码如下
from selenium import webdriver from selenium.webdriver.common.action_chains import ActionChains driver=webdriver.Chrome() driver.maximize_window() driver.get("https://www.ymgk.com/account/logon.html?backURL") driver.find_element_by_id("logonenter").click() name = driver.find_element_by_id("logonmobile1") actions = ActionChains(driver).move_to_element(name) driver.execute_script('document.getElementById("logonmobile1").value="13888888888"')
