使用 Python 发送在 Selenium 中不起作用的密钥？
Send Keys Not Working In Selenium With Python?
我正在尝试将密钥发送到某个元素，但它不起作用。
Element looks like this. Unable to send keys to all three.
代码如下：
input id="creditCardNumber" name="creditCardNumber" type="tel"
tabindex="1" data-shortname="cc" maxlength="24" class="cc-input
ncss-input pt2-sm prl4-sm prl5-md pb2-sm" placeholder="Number"
onautocomplete="off" value=""
我用这个来发送密钥：
driver.find_element_by_xpath('//*[@id="creditCardNumber"]').send_keys('0000')
driver.find_element_by_xpath('//input[@placeholder="Number"]').send_keys('0000')
给我一个错误，好像元素不可用，尽管我使用了足够长的 time.sleep.
收到错误：
driver.find_element_by_xpath('//input[@placeholder="Number"]').send_keys('0000')

我注册了 nike 以查找 creditCardNumber 字段，它在 iframe 标签下。切换到那个 iframe，然后搜索元素
<iframe sandbox="allow-scripts allow-same-origin" class="credit-card-iframe mt1 u-full-width" src="https://paymentcc.nike.com/services?id=0971b459-934f-4c0e-bdd1-6b5808a77eb1" frameborder="0" scrolling="no"></iframe>
代码：
driver.switch_to.frame(driver.find_element_by_css_selector('iframe[class="credit-card-iframe mt1 u-full-width"]'))
driver.find_element_by_id('creditCardNumber').send_keys('0000')
让我知道这是否有效
