元素定位

查找条件对象有id,name,classname,tagname等等，下面依次介绍经常使用的查找条件。Webdriver提供了对单个对象定位的方法，汇总如下：

方法	描述	实例
find_element_by_id(id)	id	find_element_by_id("kw")
find_element_by_name(name)	name	find_element_by_name("wd")
find_element_by_class_name(name)	class name	find_element_by_class_name("s_ipt")
find_element_by_tag_name(name)	tag name	find_element_by_tag_name("input")
find_element_by_xpath(xpath)	xpath	find_element_by_xpath(".//*[@id='kw']")
find_element_by_css_selector(css)	css_selector	find_element_by_css_selector("#kw")
find_element_by_link_text(linktext)	link_text	find_element_by_link_text(u'新闻')
find_element_by_partial_link_text(linktext)	partial_link_text	find_element_by_partial_link_text(u'新')

 

 

 

 

 

 

 

 

 

1.id

#coding:utf-8
from selenium import webdriver
from selenium.webdriver.common.by import  By
driver=webdriver.Firefox()
driver.get('http://www.baidu.com')
driver.find_element_by_id('kw').send_keys('webdriver')
driver.quit()

2.name

#coding:utf-8
from selenium import webdriver
from selenium.webdriver.common.by import  By
driver=webdriver.Firefox()
driver.get('http://www.baidu.com')
driver.find_element_by_name('wd').send_keys('webdriver')
driver.quit()

3.class name

#coding:utf-8
from selenium import webdriver
from selenium.webdriver.common.by import  By
driver=webdriver.Firefox()
driver.get('http://www.baidu.com')
driver.find_element_by_class_name('s_ipt').send_keys('webdriver')
driver.quit()

4.tag name

   搜索输入框”input”标记为第七个，可以使用”input”来作为条件在输入框输入字符

#coding:utf-8
from selenium import webdriver
from selenium.webdriver.common.by import  By
driver=webdriver.Firefox()
driver.get('http://www.baidu.com')
tag=driver.find_elements_by_tag_name('input')
tag[7].send_keys('webdriver')
driver.quit()

5.xpath

#coding:utf-8
from selenium import webdriver
from selenium.webdriver.common.by import  By
driver=webdriver.Firefox()
driver.get('http://www.baidu.com')
driver.find_element_by_xpath(".//*[@id='kw']").send_keys('webdriver')
driver.quit()

6.css selector

#coding:utf-8
from selenium import webdriver
from selenium.webdriver.common.by import  By
driver=webdriver.Firefox()
driver.get('http://www.baidu.com')
driver.find_element_by_css_selector("#su").click()
driver.quit()

7.linktext

#coding:utf-8
from selenium import webdriver
from selenium.webdriver.common.by import  By
driver=webdriver.Firefox()
driver.get('http://www.baidu.com')
driver.find_element_by_link_text(u'新闻').click()
driver.quit()

8.partial linktext

#coding:utf-8
from selenium import webdriver
from selenium.webdriver.common.by import  By
driver=webdriver.Firefox()
driver.get('http://www.baidu.com')
driver.find_element_by_partial_link_text(u'闻').click()
driver.quit()
