Question

我正在使用Selenium Webdriver登录网站。我尝试了多个不同的选择器，并尝试了隐式等待，但找不到元素。

    from selenium import webdriver
    from selenium.webdriver.common.by import By

    browser = webdriver.Firefox()
    url = "https://www.example.com"
    login_page = browser.get(url)

    username = browser.find_element_by_id("Email")
    # Also tried:
    # username = browser.find_element_by_xpath('//*[@id="Email"]')
    # username = browser.find_element_by_css_selector('#Email')
    username.send_keys("email")

这是html

<div class="form-group">
    <label for="Email">Email address</label>
    <div class="input-group" style="width: 100%">
        <input class="form-control email" data-val="true" data-val-length="Maximum length is 50" data-val-length-max="50" data-val-regex="Provided email address is not valid" data-val-regex-pattern="^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$" data-val-required="Email is required" id="Email" name="Email" type="email" value=""><br>
        <span class="field-validation-valid" data-valmsg-for="Email" data-valmsg-replace="true"></span>
    </div>
</div>

以下是错误消息

非常感谢任何帮助。

实际上你正在查找元素，send_keys的问题，由于元素不可见，因此无法在电子邮件输入上设置值。但正如我在提供的HTML中看到的那样，电子邮件输入元素上不存在样式属性属性，这可能使其不可见。

可能有更多具有相同ID的元素，并且您正在与其他元素进行交互，您应该尝试使用一些不同的定位器，如下所示： -

username = browser.find_element_by_css_selector('div.input-group input#Email.form-control.email')
username.send_keys("email")

或尝试查找ID为Email的所有元素，并对可见元素执行send_keys()，如下所示：

usernames = browser.find_elements_by_id('Email')

for username in usernames:
   if username.is_displayed():
        username.send_keys("email") 
        break

Selenium - Login引发了ElementNotVisibleException
