Question

我目前正处于使用python学习selenium的阶段。

以下是我试图运行的代码：

browser=webdriver.Firefox()
browser.maximize_window()
browser.get('https://netbanking.hdfcbank.com')
#print browser.page_source

elems=browser.find_elements_by_tag_name('frameset')
browser.switch_to_frame(elems[1])
browser.find_element(By.CSS_SELECTOR,"input[class='input_password']").send_keys('123456789'+Keys.ENTER)

但是我无法这样做并最终出错。以下是我看到的错误

/usr/bin/python2.7 /home/abhishek/PycharmProjects/Selenium/01_Selenium.py
Traceback (most recent call last):

以下是pagesource：

/usr/bin/python2.7 /home/abhishek/PycharmProjects/Selenium/01_Selenium.py
<html xmlns="http://www.w3.org/1999/xhtml"><head>
<title>Welcome to HDFC Bank NetBanking</title>
<script language="javascript">
    var daemon          = 'NETBANKING';
    var p_remoteaddress = '';
    var RsaAuthReq      = '';

    var l_path = window.location.pathname;

    if(l_path == undefined || l_path == '' || l_path.indexOf("/netbanking") &lt; 0){
        window.location.href = window.location.protocol + "//" + window.location.host +"/netbanking";
    }

</script>
</head>
    <frameset cols="*" rows="*" framespacing="0" frameborder="O" border="false">
        <frameset cols="*" rows="*,30" framespacing="0" frameborder="O" border="false">
            <frame scrolling="yes" noresize="true" src="RSLogin.html?v=2" name="login_page" marginheight="0" marginwidth="0" />
            <frame scrolling="no" noresize="true" src="footer.html" name="footer" marginheight="0" marginwidth="0" />
        </frameset>
    </frameset>

</html>

以下是我的疑惑：

什么是Java的python替代品 browser.swichTo（）。Frame（int arg0）？
将webelements存储在变量中并使用索引检索所需值的方法是正确的方法吗？

请咨询，谢谢！

Answer 1

什么是Java的browser.swichTo（）的python替代.Frame（int arg0）？

这与Python非常相似：

number = 0  # first frame
browser.switch_to.frame(number)

将webelements存储在变量中并使用索引检索所需值的方法是正确的方法吗？

是的，如果elems内的元素是frame元素，它可能会起作用。

在这种情况下，您可以执行以下操作：

browser.switch_to.frame(0)

或：

browser.switch_to.frame("login_page")

使用Python在Selenium中选择带索引的框架集
