Selenium三种等待方式的使用

from selenium import webdriver  
from selenium.webdriver.common.by import By  
from selenium.webdriver.support.ui import WebDriverWait  
from selenium.webdriver.support import expected_conditions as EC  
  
driver = webdriver.Chrome()  
driver.get("http://example.com")  
  
try:  
    element = WebDriverWait(driver, 10).until(  
        EC.visibility_of_element_located((By.ID, "myElement"))  
finally:  
    driver.quit()

from selenium import webdriver  
  
driver = webdriver.Chrome()  
driver.implicitly_wait(10)  # 设置隐式等待为 10 秒  
driver.get("http://example.com")  
  
# 接下来查找元素的操作，都会等待最多 10 秒  
element = driver.find_element_by_id("myElement")  
  
driver.quit()

import time  
from selenium import webdriver  
  
driver = webdriver.Chrome()  
driver.get("http://example.com")  
  
time.sleep(10)  # 程序暂停 10 秒  
  
element = driver.find_element_by_id("myElement")  
  
driver.quit()
