Selenium

Question

我今天开始使用 selenium，但我在查找这些元素并在第一个元素中填充一个值并单击第二个元素时遇到了问题。

<input class="inputDefault-_djjkz input-cIJ7To" name="username" type="text" placeholder="Che nome vuoi usare?" maxlength="999" value="">

<input class="inputDefault-3JxKJ2 input-3ITkQf" type="checkbox" style="width: 24px; height: 24px;">

这是我的代码

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


# Content to fill - <input class="inputDefault-_djjkz input-cIJ7To" name="username" type="text" placeholder="Che nome vuoi usare?" maxlength="999" value="">
# {"method":"css selector","selector":"[name="Che nome vuoi usare?"]"}

# Checkbox - <input class="inputDefault-3JxKJ2 input-3ITkQf" type="checkbox" style="width: 24px; height: 24px;">

driver = webdriver.Chrome()
driver.get("https://discord.gg/NGvXRfrmUE")
name = driver.find_element_by_class_name("inputDefault-_djjkz input-cIJ7To").send_keys("Test")
button = driver.find_element_by_class_name("inputDefault-3JxKJ2 input-3ITkQf").click

我第一次得到这个例外

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"css selector","selector":".inputDefault-_djjkz input-cIJ7To"}

这是第二个

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"css selector","selector":".inputDefault-3JxKJ2 input-3ITkQf"}

Answer 1

因为name可用，你应该使用name attribute。

driver.find_element_by_name('username').send_keys("Test")

我可以在我这边看到这个 HTML :

<input class="inputDefault-_djjkz input-cIJ7To inputField-4g7rSQ" name="email" type="text" placeholder="" aria-label="Email or Phone Number" autocomplete="off" maxlength="999" spellcheck="false" value="">

所以这里 name 是 email，所以应该试试 :

driver.find_element_by_name('email').send_keys("Test")

更新 1：

driver.get("https://discord.com/invite/NGvXRfrmUE")
driver.maximize_window()
wait = WebDriverWait(driver, 10)
wait.until(EC.element_to_be_clickable((By.NAME, "username"))).send_keys('Test')

进口：

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