python - 处理帧时的 Slate 元素引用异常

问题描述

from selenium import webdriver

driver = webdriver.Chrome(executable_path=r'C:\Users\satyanarayana\Downloads\chromedriver_win32\chromedriver.exe')
driver.get("https://www.olx.in/")

frames_tag = driver.find_elements_by_tag_name("iframe")
print(len(frames_tag))
for i in range(0,len(frames_tag)):
    driver.switch_to.frame(frames_tag[i])

driver.quit()

我收到以下异常。有人可以帮我弄清楚代码有什么问题。

Traceback (most recent call last):

解决方案

当您切换到<iframe>驱动程序上下文更改为<iframe>并且只能识别其中的元素。<iframe>完成后需要退出

for i in range(0,len(frames_tag)):
    driver.switch_to.frame(frames_tag[i])
    driver.switch_to.default_content()
