在处理Selenium中的元素等待问题时,可以采用以下几种策略:
强制等待:
time.sleep()
time.sleep(3)
sleep
隐式等待:
implicitly_wait()
driver
driver.implicitly_wait(10)
显式等待:
WebDriverWait
WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.ID, "okkk")))
Fluent Wait:
WebDriverWait(driver, 10, poll_frequency=0.5).until(EC.presence_of_element_located((By.ID, "okkk")))
在实际应用中,推荐使用显式等待(WebDriverWait和expected_conditions模块),因为它可以根据具体条件进行等待,避免不必要的延迟,提高脚本的执行效率。隐式等待可以作为一种补充策略,但不建议过度依赖time.sleep()。
