背景知识  发送回车键

 

 

from selenium.webdriver.common.keys import Keys

driver.find_element(By.CSS_SELECTOR, loc).send_keys(Keys.ENTER)

 

 

隐式等待的意思是 当符合条件就结束等待，不符合持续等待

对比    第一种  强制等待

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from time import sleep
def wait(loc):
    ele=driver.find_element(By.CSS_SELECTOR,loc)
    ele.send_keys("1")
    sleep(1)
    ele.send_keys(Keys.ENTER)

if __name__ == '__main__':
    driver=webdriver.Chrome()
    driver.get('https://www.baidu.com')
    loc='input#kw'
    sleep(3)
    print("已经打开百度浏览器，等待3秒")
    wait(loc)
    sleep(3)
    print("回车后，等待3秒")

对比 第二种   隐式等待

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from time import sleep
def wait(loc):
    ele=driver.find_element(By.CSS_SELECTOR,loc)
    ele.send_keys("1")
    
    ele.send_keys(Keys.ENTER)

if __name__ == '__main__':
    driver=webdriver.Chrome()
    driver.get('https://www.baidu.com')
    loc='input#kw'
    driver.implicitly_wait(3)
    print("已经打开百度浏览器，全局情况下  找元素 等待时长最久3秒")
    wait(loc)
    sleep(3)
    print("回车后，等待3秒")
