這個可以說是被問爛的題了，判斷元素存在方法有三種： 方法一，用try...except... ~~~ def is_element_exsist(driver, locator): ''' 判斷元素是否存在,存在返回True,不存返回False :param locator: locator為元組類型，如("id", "yoyo") :return: bool值，True or False ''' try: driver.find_element(*locator) return True except Exception as msg: print("元素%s找不到：%s" % (locator, msg)) return False if __name__ == '__main__': loc1 = ("id", "yoyo") # 元素1 print(is_element_exsist(driver, loc1)) ~~~ 方法二：用elements定義一組元素方法 ~~~ def is_element_exsist1(driver, locator): ''' 判斷元素是否存在,存在返回True,不存返回False :param locator: locator為元組類型，如("id", "yoyo") :return: bool值，True or False ''' eles = driver.find_elements(*locator) if len(eles) < 1: return False else: return True if __name__ == '__main__': loc1 = ("id", "yoyo") # 元素1 print(is_element_exsist1(driver, loc1)) ~~~ (強烈推薦！)方法三：結合WebDriverWait和expected\_conditions判斷 ~~~ from selenium import webdriver from selenium.webdriver.support import expected_conditions as EC from selenium.webdriver.support.ui import WebDriverWait def is_element_exsist2(driver, locator): ''' 結合WebDriverWait和expected_conditions判斷元素是否存在, 每間隔1秒判斷一次，30s超時，存在返回True,不存返回False :param locator: locator為元組類型，如("id", "yoyo") :return: bool值，True or False ''' try: WebDriverWait(driver, 30, 1).until(EC.presence_of_element_located(locator)) return True except: return False if __name__ == '__main__': loc1 = ("id", "yoyo") # 元素1 print(is_element_exsist2(driver, loc1)) ~~~
