问题描述

您好，我正在尝试使用 Selenium 和 Python 为网站

我的代码如下:

BASE_URL = 'https://mail.protonmail.com/create/new?language=en'driver = webdriver.Chrome(executable_path='./drivers/chromedriver')driver.get(BASE_URL)river.find_element_by_xpath('//*[@id="username"]').send_keys('someStringValue')

执行以下代码后，出现错误:

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"xpath","selector":"//*[@id="username"]"}(会话信息:chrome=83.0.4103.97)

有什么建议吗?

解决方案

Email Address 字段位于 </code> 中，因此您必须:</p><ul><li><p>诱导 <em>WebDriverWait</em> 使所需的<em>框架可用并切换到它</em>.</p></li><li><p>诱导 <em>WebDriverWait</em> 使所需的<em>元素可点击</em>.</p></li><li><p>您可以使用以下任一</p><hr/><h2>参考</h2><p>您可以在以下位置找到相关讨论:</p><ul><li>iframe下#document的处理方式</li><li>通过 Selenium 和 python 切换到 iframe</li></ul><p>Hi I was trying to type the username field using Selenium and Python for the website https://mail.protonmail.com/create/new?language=en. </p> <p>From the developer tool, I am able to inspect the item using CSSSelector/Xpath or other way. But when I am running the pthon script its not working. Screenshot attached:</p> <p></p> <p>My code is like the following:</p><pre><code class='language-python'>BASE_URL = 'https://mail.protonmail.com/create/new?language=en' driver = webdriver.Chrome(executable_path='./drivers/chromedriver') driver.get(BASE_URL) river.find_element_by_xpath('//*[@id="username"]').send_keys('someStringValue') </code></pre><p>And after executing the following code, geetting the error: </p><pre><code class='language-python'>selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"xpath","selector":"//*[@id="username"]"} (Session info: chrome=83.0.4103.97) </code></pre><p>Any suggestion?</p><div class="h2_lin"> 解决方案 </div><p>The <em>Email Address</em> field is within an <code><iframe></code> so you have to:</p> <ul> <li><p>Induce <em>WebDriverWait</em> for the desired <em>frame to be available and switch to it</em>.</p> </li> <li><p>Induce <em>WebDriverWait</em> for the desired <em>element to be clickable</em>.</p> </li> <li><p>You can use either of the following Locator Strategies:</p> </li> <li><p>Using <code>CSS_SELECTOR</code>:</p><pre><code

<code>XPATH</code>:</p><pre><code class='language-python'> driver.get("https://mail.protonmail.com/create/new?language=en") WebDriverWait(driver,

10).until(EC.element_to_be_clickable((By.XPATH, "//input[@class='input' and @id='username']"))).send_keys("FunnyBoss") </code></pre><p> </li> <li><p><strong>Note</strong> : You have to add the
