测试代码
# coding=utf-8
url='file:///Users/yeap/local/personal/master/selenium_/webdriver_guide/09/checkbox.html'
from selenium import webdriver
ff=webdriver.Firefox()
ff.get(url)
e=ff.find_element_by_xpath('//div[@class="well1"]')
print('*'*10)
print e.get_attribute('name') # 输出 well1
print('*'*10)
e=e.find_elements_by_xpath('//input[@type="checkbox"]')
print len(e) # 输出6 不是3
for _ in e:
print('*'*10)
print _.get_attribute('id')
print('*'*10)
ff.quit()
搞不懂清楚的是为何 e=ff.find_element_by_xpath('//div[@class="well1"]') 定位后，
使用定位后的 e 再次定位//input[@type="checkbox],
结果打印出来的是 6 个；按照我的理解，应该是 3 个；求解,谢谢各位看官
建议你再 Chrome 里面先试一下: F12 后 ctrl+F 打开搜索框, 搜索框支持 XPATH 和 css, 可以先看看这 2 种方法搜索的结果如何.
