如何使用 Selenium 和 Python 根据标签名称和属性查找 Web 元素

发布于 2025-01-19 19:00:26 字数 1030 浏览 0 评论 0原文

我正在尝试使用Selenium登录我的Instagram帐户。为此，我需要将我的用户名和密码填充到登录表单中。

用户名输入栏具有标签INPUT和名称等于用户名。有没有一种方法可以仅使用name属性和标签名来检索此输入栏？我知道我可以使用XPATH和类名称，但是我只想使用name属性来执行此操作。

我尝试了下面的代码，但有错误。

代码：

username = driver.find_element(by = By.CSS_SELECTOR, value = "input[name = 'username']")
print(username.get_attribute("class"))

输出：

File "d:\Personal\CS\Bots\Instabot\msg.py", line 17, in <module>
    username = driver.find_element(by = By.CSS_SELECTOR, value = "input[name = 'username']")

编辑：

我也尝试过类名称和XPATH，但它们不起作用

XPath：

username = driver.find_element(by = By.XPATH, value = '//*[@id="loginForm"]/div/div[1]/div/label/input')
print(username.get_attribute("class"))

class：

username = driver.find_element(by = By.CSS_SELECTOR, value = 'input._2hvTZ pexuQ zyHYP')
print(username.get_attribute("class"))

我在这里做错了什么？

原文

I am trying to log into my Instagram account using Selenium. For that, I need to fill in my username and password into the login form.

The username input bar has the tag input and the name equal to username. Is there a way to retrieve this input bar using only the name attribute and the tag name? I know I can use the XPath and the class name, but I want to do this using the name attribute only.

I tried the code below but got an error.

Code:

username = driver.find_element(by = By.CSS_SELECTOR, value = "input[name = 'username']")
print(username.get_attribute("class"))

Output:

File "d:\Personal\CS\Bots\Instabot\msg.py", line 17, in <module>
    username = driver.find_element(by = By.CSS_SELECTOR, value = "input[name = 'username']")

Edit:

I tried the class name and the XPath too but they don't work either

XPath:

username = driver.find_element(by = By.XPATH, value = '//*[@id="loginForm"]/div/div[1]/div/label/input')
print(username.get_attribute("class"))

Class:

username = driver.find_element(by = By.CSS_SELECTOR, value = 'input._2hvTZ pexuQ zyHYP')
print(username.get_attribute("class"))

What am I doing wrong here?

你没看错。 电话号码、用户名或电子邮件 字段具有姓名 > 设置为用户名。

<input aria-label="Phone number, username, or email" aria-required="true" autocapitalize="off" autocorrect="off" maxlength="75" name="username" type="text" class="_2hvTZ pexuQ zyHYP" value="">

因此，要定位该元素，您可以使用以下任一定位器策略：

< p>使用css_selector：

element = driver.find_element(By.CSS_SELECTOR, "input[name='用户名']")

使用xpath：

element = driver.find_element(By.XPATH, "//input[@name='用户名']")

由于该元素是一个交互式元素，因此非常适合定位您需要诱导的元素WebDriver等待 element_to_be_clickable() 并且您可以使用以下任一定位策略：

使用CSS_SELECTOR：

element = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input[name='用户名']")))

使用XPATH：

element = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@name='用户名']")))

注意：您必须添加以下导入：

从 selenium.webdriver.support.ui 导入 WebDriverWait
从 selenium.webdriver.common.by 导入
从 selenium.webdriver.support 导入预期条件作为 EC

You saw it right. The Phone number, username, or email <input> field has the name set as username.

<input aria-label="Phone number, username, or email" aria-required="true" autocapitalize="off" autocorrect="off" maxlength="75" name="username" type="text" class="_2hvTZ pexuQ zyHYP" value="">

So to locate the element you can use either of the following Locator Strategies:

Using css_selector:

element = driver.find_element(By.CSS_SELECTOR, "input[name='username']")

Using xpath:

element = driver.find_element(By.XPATH, "//input[@name='username']")

As the element is an interactive element ideally to locate the element you need to induce WebDriverWait for the element_to_be_clickable() and you can use either of the following locator strategies:

Using CSS_SELECTOR:

element = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input[name='username']")))

Using XPATH:

element = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@name='username']")))

Note : You have to add the following imports :

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
