使用 Selenium 在选项卡之间切换并对个人执行操作 [英] switch between tabs and perform action on individual using Selenium

问题描述

我正在尝试提取 URL，将它们打开到一个新选项卡中，然后执行一些操作.我的代码是-

urls = self.driver.find_elements_by_xpath('//div[@id="maincontent"]/table/tbody/tr/td//a[@href]')对于网址中的网址:尝试:href = url.get_attribute("href")[28:]打印href动作 = 动作链(self.driver)url_1 = self.driver.find_element_by_xpath('//*[@href="'+href+'"]')actions.key_down(Keys.CONTROL).click(url_1).key_up(Keys.CONTROL).perform()除了例外，e:打印e动作1 =动作链(self.driver)actions1.key_down(Keys.CONTROL).key_down(Keys.TAB).key_up(Keys.TAB).key_up(Keys.CONTROL).perform()打印嗨"show_report = self.driver.find_element_by_xpath('//*[@value="Show Report(s)"]')show_report.click()

它在新选项卡中打开 URL，但不对它们执行操作.我该怎么办??

解决方案

您需要将焦点转移到新选项卡上，因为它们通常在后台打开.然后你需要抓住当前标签的句柄.

在此处对此进行了描述:

import selenium.webdriver 作为 webdriver导入 selenium.webdriver.support.ui 作为 ui从 selenium.webdriver.common.keys 导入密钥从时间导入睡眠浏览器 = webdriver.Firefox()browser.get('https://www.google.com?q=python#q=python')first_result = ui.WebDriverWait(browser, 15).until(lambda 浏览器:browser.find_element_by_class_name('rc'))first_link = first_result.find_element_by_tag_name('a')# 保存开窗器(当前窗口，不要误认为是tab...不一样)main_window = browser.current_window_handle# 通过在元素上发送击键来在新选项卡中打开链接# 使用:Keys.CONTROL + Keys.SHIFT + Keys.RETURN 打开堆栈顶部的选项卡first_link.send_keys(Keys.CONTROL + Keys.RETURN)# 切换标签到新标签，我们假设它是右边的下一个browser.find_element_by_tag_name('body').send_keys(Keys.CONTROL + Keys.TAB)# 将焦点放在当前窗口上，实际上将焦点放在当前可见的选项卡上browser.switch_to_window(main_window)#在这个页面上做任何你必须做的事情，我们现在就睡吧睡觉(2)# 关闭当前标签browser.find_element_by_tag_name('body').send_keys(Keys.CONTROL + 'w')# 将焦点放在当前窗口上，这将是窗口开启器browser.switch_to_window(main_window)

I am trying to extract URLs, open them into a new tab and then perform some actions. My code is-

urls = self.driver.find_elements_by_xpath('//div[@id="maincontent"]/table/tbody/tr/td//a[@href]')
        for url in urls:

            try:
                href = url.get_attribute("href")[28:]
                print href
                actions = ActionChains(self.driver)
                url_1 = self.driver.find_element_by_xpath('//*[@href="'+href+'"]')
                actions.key_down(Keys.CONTROL).click(url_1).key_up(Keys.CONTROL).perform()
            except Exception, e:
                print e

        actions1 = ActionChains(self.driver)      
        actions1.key_down(Keys.CONTROL).key_down(Keys.TAB).key_up(Keys.TAB).key_up(Keys.CONTROL).perform()
        print "hi"
        show_report = self.driver.find_element_by_xpath('//*[@value="Show Report(s)"]')
        show_report.click()

It opens the URLs in new tabs but is not performing action on them. What should I do??

解决方案

You'll need to change focus to the new tab as they usually get opened in the background. Then you'll need to grab a handle for the now current tab.

This is described here:

import selenium.webdriver as webdriver
import selenium.webdriver.support.ui as ui
from selenium.webdriver.common.keys import Keys
from time import sleep    

browser = webdriver.Firefox()
browser.get('https://www.google.com?q=python#q=python')
first_result = ui.WebDriverWait(browser, 15).until(lambda browser: browser.find_element_by_class_name('rc'))
first_link = first_result.find_element_by_tag_name('a')

# Save the window opener (current window, do not mistaken with tab... not the same)
main_window = browser.current_window_handle

# Open the link in a new tab by sending key strokes on the element
# Use: Keys.CONTROL + Keys.SHIFT + Keys.RETURN to open tab on top of the stack 
first_link.send_keys(Keys.CONTROL + Keys.RETURN)

# Switch tab to the new tab, which we will assume is the next one on the right
browser.find_element_by_tag_name('body').send_keys(Keys.CONTROL + Keys.TAB)

# Put focus on current window which will, in fact, put focus on the current visible tab
browser.switch_to_window(main_window)

# do whatever you have to do on this page, we will just got to sleep for now
sleep(2)

# Close current tab
browser.find_element_by_tag_name('body').send_keys(Keys.CONTROL + 'w')

# Put focus on current window which will be the window opener
browser.switch_to_window(main_window)
