我一直在尝试使用硒抓取bookmyshow网站的网页.加载页面后，将弹出2个弹出窗口.在这两个中，我们必须单击所需的按钮以将其关闭.当我尝试查找那些元素时，出现错误.我通过使用sleep()使驱动程序完全加载了页面.但是，我仍然无法做到这一点.

I have been trying to scrape a web page of bookmyshow site using selenium. When the page is loaded, 2 popups will come. In those two we have to click on the required buttons to close them. When i try to find those elements, I am getting error. I made the driver to load the page completely by using sleep(). But still, I am unable to do so.

代码是:

from bs4 import BeautifulSoup import requests from selenium import webdriver from time import sleep s = requests.session() driver = webdriver.Chrome('F:\chromedriver') driver.get("in.bookmyshow/booktickets/VMAX/2061") sleep(40) e2 = driver.find_element_by_class_name('wzrkPPwarp') e2.click() print("done") e1 = driver.find_element_by_class_name('No thanks') e1.click() element = driver.find_element_by_class_name('__buytickets') element.click() element1 = driver.find_element_by_class_name('rem-seats') print(element1.text)

我得到的输出是:

NoSuchElementException: Message: no such element: Unable to locate element: {"method":"class name","selector":"wzrkPPwarp"} (Session info: chrome=64.0.3282.140) (Driver info: chromedriver=2.33.506120 (e3e53437346286c0bc2d2dc9aa4915ba81d9023f),platform=Windows NT 10.0.16299 x86_64)

该怎么做?如何单击这两个元素?

How to do this?How to click on those two elements?

推荐答案

在对 iframe 内部的任何元素执行任何操作之前，我们已切换到相应的 frame 这个.

Before performing any action on any elements which are inside the iframe we have switch to respective frame like this.

# To switch to frame driver.switch_to.frame(driver.find_element_by_id("wiz-iframe")) # Clicking on the element inside the frame e2 = driver.find_element_by_xpath("//div[@class='wzrkPPwarp']//a") e2.click()

一旦对iframe中的元素执行了必需的操作，我们就将控件带回默认内容，以便在主窗口上执行这样的操作.

And once the required action performed on the element in side the iframe we have bring the control back to default content to perform action on main window like this.

# Switching back to main content driver.switch_to_default_content() # Then only we can access elements e3 = driver.find_element_by_xpath("//button[@class='No thanks']") e3.click()
