在选项卡之间切换并使用Selenium对单个对象执行操作

Question

我正在尝试提取URL，将其打开到新选项卡中，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]')
        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()

它会在新选项卡中打开URL，但不会对其执行任何操作。我该怎么办？？

您需要将焦点更改为新标签，因为它们通常会在后台打开。然后，您需要抓住当前当前选项卡的句柄。

这在这里描述：
