第二记：8种定位方式

1.经过id定位 find_element_by_id()

driver.find_element_by_id(“kw”).send_keys(“测试") 用firebug经过查看页面元素，找到搜索输入框id属性值，输入关键字搜索
driver.find_element_by_id("su").click() 用firebug经过查看页面元素，找到搜索按钮id属性值，而后click点击




2.经过name定位 find_element_by_name()

coding:utf-8

from selenium import webdriver
driver = webdriver.Firefox()

url = "http://tieba.baidu.com/"
driver.get(url)
driver.find_element_by_name("kw1").send_keys("hao")




3.经过class定位 find_element_by_class_name()

coding:utf-8
from selenium import webdriver
import time

url = "https://www.baidu.com/"
driver = webdriver.Firefox()

driver.get(url)
time.sleep(3)
driver.find_element_by_class_name("s_ipt").send_keys("123")




4.经过tag定位 find_element_by_tag_name()

coding:utf-8
from selenium import webdriver
import time

url = "https://www.baidu.com/"
driver = webdriver.Firefox()

driver.get(url)
time.sleep(3)
driver.find_element_by_tag_name("input").send_keys("hao") 这里经过标签订位百度输入框是会报错的，由于页面上input标签有不少个




5.经过link定位 find_element_by_link_text()
6.经过partial link定位 find_element_by_partial_link_text()

coding:utf-8
from selenium import webdriver
import time

url = "https://www.baidu.com/"
driver = webdriver.Firefox()

driver.get(url)
time.sleep(3)

driver.find_element_by_link_text("hao123").click()

& driver.find_element_by_partial_link_text("hao1").click()




7.XPath 是一种在XML 文档中定位元素的语言

coding:utf-8
from selenium import webdriver
import time

url = "https://www.baidu.com/"
driver = webdriver.Firefox()

driver.get(url)

driver.find_element_by_xpath("//input[@id='kw']").send_keys("123")
driver.find_element_by_xpath(".//*[@id='su']").click()




8.CSS(Cascading Style Sheets)是一种语言，它被用来描述HTML 和XML 文档的表现

coding:utf-8
from selenium import webdriver
import time

url = "https://www.baidu.com/"
driver = webdriver.Firefox()

driver.get(url)
time.sleep(3)

driver.find_element_by_css_selector("#kw").send_keys("123")
driver.find_element_by_css_selector("#su").click()

Selenium提供了八种单数定位，一样也有八种复数定位 定位一组元素取下标，如：find_elements_by_class_name(“xx”)[1]
