Javascript Python + Selenium + PhantomJS 脚本中的警报

Question

我尝试 "click" Javascript 使用 Python 脚本在 DSL 调制解调器中提醒重新启动确认，如下所示：

#!/usr/bin/env python

import selenium
import time
from selenium import webdriver

cap = {u'acceptSslCerts': True,
u'applicationCacheEnabled': True,
u'browserConnectionEnabled': True,
u'browserName': u'phantomjs',
u'cssSelectorsEnabled': True,
u'databaseEnabled': False,
u'driverName': u'ghostdriver',
u'driverVersion': u'1.1.0',
u'handlesAlerts': True,
u'javascriptEnabled': True,
u'locationContextEnabled': False,
u'nativeEvents': True,
u'platform': u'linux-unknown-64bit',
u'proxy': {u'proxyType': u'direct'},
u'rotatable': False,
u'takesScreenshot': True,
u'version': u'1.9.8',
u'webStorageEnabled': False}


driver = webdriver.PhantomJS('/usr/lib/node_modules/phantomjs/bin/phantomjs', desired_capabilities=cap)
driver.get('http://username:passwd@192.168.1.254')
sbtn = driver.find_element_by_id('reboto_btn')
sbtn.click()
time.sleep(4)
al = driver.switch_to_alert()

print al.accept()

但是，即使我在 desired_capabilities 中设置了 handlesAlerts，我也会在下面粘贴异常。

我该如何解决？异常原因是什么？

Answer 1

在java,driver.switchTo().alert().accept();会做的工作。

我不确定，你为什么要使用 "print al.accept()"，可能是你想打印文本？然后 alert.getText() 将在 java 中执行，如果我错了，抱歉，因为我确定在 python.

中

Answer 2

由于 PhantomJs 不支持警告框。您需要为此使用执行器。

driver.execute_script("window.confirm = function(msg) { return true; }");
