python+selenium初级（10）—八大定位方法

selenium定位有八种方法，id、name、class、tag、link_text、partial_link_text、css、xpath

1.利用id定位元素

#coding=utf-8

from selenium import webdriver
import  time
driver =webdriver.Firefox()
driver.get('http://rc.dodowork.cn/')
driver.find_element_by_id('username').clear()
driver.find_element_by_id('username').send_keys('15619026999')

2.利用class定位元素

#coding=utf-8

from selenium import webdriver
import time
driver =webdriver.Firefox()
driver.get('http://rc.dodowork.cn/')
driver.find_element_by_id('username').clear()
driver.find_element_by_id('username').send_keys('15619026989')
driver.find_element_by_id('password').clear()
driver.find_element_by_id('password').send_keys('liyan111')
driver.find_element_by_class_name('inpu_btn').click()3.利用name定位元素
# coding=utf-8

from selenium import webdriver

driver = webdriver.Chrome()
driver.maximize_window()
driver.implicitly_wait(6)

driver.get("https://www.baidu.com")
try:
driver.find_element_by_name("wd") # 这里百度搜索输入框有name = 'wd'这个节点信息
print ('test pass: element found by name value')
except Exception as e:
print ("Exception found", format(e))

driver.quit()

4.利用tag定位元素
# coding=utf-8

from selenium import webdriver

driver = webdriver.Chrome()
driver.maximize_window()
driver.implicitly_wait(6)

driver.get("https://www.baidu.com")
try:
driver.find_element_by_tag_name("form")
print ('test pass: tag name found')
except Exception as e:
print ("Exception found", format(e))

driver.quit() 5.利用link_text定位元素
# coding=utf-8

from selenium import webdriver

driver = webdriver.Chrome()
driver.maximize_window()
driver.implicitly_wait(6)

driver.get("https://www.baidu.com")
try:
driver.find_element_by_link_text("新闻")
print ('test pass: element found by link text')
except Exception as e:
print ("Exception found", format(e))

driver.quit()

6.利用partial_link_text定位元素
# coding=utf-8

from selenium import webdriver

driver = webdriver.Chrome()
driver.maximize_window()
driver.implicitly_wait(6)

driver.get("https://www.baidu.com")
try:
driver.find_element_by_partial_link_text("主页").click()
print ('test pass: element found by partial link text')
except Exception as e:
print ("Exception found", format(e))

driver.quit()

7.利用CSS定位元素
# coding=utf-8

from selenium import webdriver

driver = webdriver.Chrome()
driver.maximize_window()
driver.implicitly_wait(6)

driver.get("https://www.baidu.com")
try:
driver.find_element_by_css_selector("#su") # 找 百度一下 这个按钮
print ('test pass: element found by css selector')
except Exception as e:
print ("Exception found", format(e))

driver.quit() 8.利用xpath定位元素
login_form = driver.find_element_by_xpath("/html/body/form[1]")
login_form = driver.find_element_by_xpath("//form[1]")
log
4000
in_form = driver.find_element_by_xpath("//form[@id='loginForm']")
