android - 无法在 Selenium 中使用移动模拟 chromedriver 中的 click()

Question

我正在尝试使用移动模拟 Chrome 浏览器测试内部 Web 应用程序的登录过程。我正在使用 Python 3.6.4。

它按名称找到元素，但不会点击它!

这是我的代码:

from selenium import webdriver
enter code herefrom selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import Select
import time

mobile_emulation = {

    "deviceMetrics": { "width": 360, "height": 640, "pixelRatio": 3.0 },

    "userAgent": "Mozilla/5.0 (Linux; Android 4.2.1; en-us; Nexus 5 Build/JOP40D) AppleWebKit/535.19 (KHTML, like Gecko) Chrome/18.0.1025.166 Mobile Safari/535.19" }

chrome_options = Options()
chrome_options.add_experimental_option("mobileEmulation", mobile_emulation)
driver = webdriver.Chrome(chrome_options = chrome_options)

driver.get("https://internalweburlhere")
elem = driver.find_element_by_id("txtEmailAddress")
elem.clear()
elem.send_keys("Username")
elem = driver.find_element_by_id("txtPassword")
elem.send_keys("1234")
print("Password Entered")
driver.find_element_by_id("btnSignIn").click()
print("Logged In")

</div>
</div>
</div>

有人可以建议我如何解决这个问题吗？有趣的是，当我在 Android Chrome 浏览器上的 BrowserStack 上运行类似代码时，点击会按预期工作。只是当我在本地运行它时不是。

某个时间元素出现在 DOM 中，但 selenium 未能等到属性被删除。可能的猜测是在您的情况下，即使您看不到任何异常，它也不会等待从 input 标记中删除属性 disabled="disabled" 并执行点击。

因此在这种情况下，您必须在浏览器中注入(inject) javascript 并执行以下操作:

element = driver.find_element_by_id("btnSignIn")
driver.execute_script('arguments[0].click();', element)
