python 使用 selenium webdriver

Question

我正在尝试打开“digikey”网站并使用搜索栏发送一些数据。这是代码示例，但看起来发送键不起作用。我需要帮助。谢谢你。

import time
from openpyxl import load_workbook
from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Chrome(executable_path='C:/Users/amuri/AppData/Local/Microsoft/WindowsApps/PythonSoftwareFoundation.Python.3.9_qbz5n2kfra8p0/site-packages/chromedriver.exe')
driver.implicitly_wait(3)

url ='https://www.digikey.com/'
driver.get(url)
print(driver.title)
elem = driver.find_element_by_xpath("/html/body/header/div[2]/div[1]/div/div[2]/div[2]/input")
elem.click()
elem.send_keys("myString")
print(elem.text)

Answer 1

供 elem 使用 css选择器，不长 xpath:

elem = driver.find_element_by_css_selector("#main-layout-content .header__searchinput")

header__searchinput class 不是唯一的，这就是我使用 main-layout-content 的原因id 作为 parent 。
还添加显式等待:

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

wait = WebDriverWait(driver, timeout=30)
wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, "#main-layout-content .header__searchinput")))
elem = driver.find_element_by_css_selector("#main-layout-content .header__searchinput")
elem.click()
elem.send_keys("myString")
