Question

我正在使用python和selenium来测试梦幻足球的某些功能。到目前为止，这是我的代码（我刚刚开始）。

import time
from selenium import webdriver

driver = webdriver.Chrome('C:\\Users\\202300Fontenot\\Desktop\\3\\chromedriver.exe')
driver.get('http://games.espn.com/ffl/signin?redir=http%3A%2F%2Fgames.espn.com%2Fffl%2Fclubhouse%3FseasonId%3D2018%26leagueId%3D49607%26teamId%3D4');
driver.implicitly_wait(10)
time.sleep(10)
search_box = driver.find_element_by_xpath('//*[@id="did-ui-view"]/div/section/section/form/section/div[1]/div/label/span[2]/input')
search_box.send_keys('email@icloud.com')
search_box.submit()
time.sleep(5)
driver.quit()

这只是尝试在框中输入电子邮件地址。我每次都会收到此错误：

Traceback (most recent call last):

    search_box = driver.find_element_by_xpath('//*[@id="did-ui-view"]/div/section/section/form/section/div[1]/div/label/span[2]/input')

感谢您的帮助。

Answer 1

首先，您需要使用其名称切换到iframe：

disneyid-iframe

如果不是唯一选择XPATH，则可以使用CSS选择器：

div.field-username-email输入[type ='email']

这将使驱动程序查找并填写您的字段。

Answer 2

您的问题是，您要选择的输入位于iframe内部。您必须首先告诉驱动程序切换到iframe，然后执行xpath选择。

driver.switch_to.frame("disneyid-iframe")
driver.find_element_by_xpath("//input[@type='email']").send_keys('email@icloud.com')

Answer 3

在python中使用XPath您需要提供

的字符串

driver.find_element_by_xpath

下面的示例代码

("//*[@id=\"did-ui-view\"]/div/section/section/form/section/div[1]/div/label/span[2]/input")
