No such element: Unable to locate element with ID in Python/Selenium
在 Python 中使用 Selenium 在 USPS 职业网站上的搜索字段中输入文本时出现以下错误：
selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"css selector","selector":"[]"}

请发送帮助。
所需元素是动态元素，因此要使用 Selenium 在元素上定位/click()，您需要为 element_to_be_clickable() 诱导 WebDriverWait，并且可以使用以下任一定位器策略：
使用 CSS_SELECTOR:
driver = webdriver.Chrome("C:/Users/NAME/Downloads/chromedriver_win32/chromedriver.exe") driver.get("https://wp1-ext.usps.gov/sap/bc/webdynpro/sap/hrrcf_a_unreg_job_search#") elem = driver.find_element_by_name("WD40") elem.send_keys("denver") <input id="WD40" ct="I" lsdata="{29:'WD3E'}" lsevents="{Change:[{ResponseData:'delta',EnqueueCardinality:'single'},{}]}" type="text" tabindex="0" ti="0" class="lsField__input" autocomplete="off" autocorrect="off" name="WD40" style="width:350px;" title=""> driver.get("https://wp1-ext.usps.gov/sap/bc/webdynpro/sap/hrrcf_a_unreg_job_search#") WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR,"input.lsField__input"))).send_keys("denver") driver.get("https://wp1-ext.usps.gov/sap/bc/webdynpro/sap/hrrcf_a_unreg_job_search#") WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH,"//input[@class='lsField__input']"))).send_keys("denver") from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.common.by import By from selenium.webdriver.support import expected_conditions as EC使用 XPATH:
