selenium webdriver从安装到使用（python语言），显示等待和隐性等待用法，切换窗口或者frame，弹框处理，下拉菜单处理，模拟鼠标键盘操作等 selenium的用法

driver = webdriver.Firefox()  #将火狐浏览器的驱动赋值给driver，这样driver就可以有很多可以使用的方法了，比如下面这个打开一个网址的方法

driver = webdriver.Chrome() #获取谷歌浏览器驱动

driver = webdriver.Ie() #获取IE浏览器驱动

driver.get('http://www.baidu.com')

driver.quit()  #关闭driver

driver.close()  #关闭当前页面

# encoding=utf-8

from selenium import webdriver

driver = webdriver.Chrome()

driver.get(r'http://www.baidu.com')

 

driver.maximize_window()

print(driver.title)

driver.find_element_by_id('su')  #寻找id为’su’的元素

driver.find_element_by_name('wd')  #寻找name为’wd’的元素

driver.find_element_by_link_text('贴吧')  #寻找链接文本信息为’贴吧’的元素

driver.find_element_by_class_name('c-tips-container')  #寻找classname为’c-tips-container’的元素

driver.find_element_by_tag_name('div')  #寻找标签名带有’div’的元素

driver.find_element_by_partial_link_text('新')  #寻找链接文本部分带有’新’的元素

driver.find_element_by_xpath('//*[@]')  #寻找id属性为kw的元素

driver.find_element_by_css_selector('#kw')  #寻找id属性为kw的元素
