第二記：8種定位方式

1.經過id定位 find_element_by_id()

driver.find_element_by_id(「kw」).send_keys(「測試") 用firebug經過查看頁面元素，找到搜索輸入框id屬性值，輸入關鍵字搜索
driver.find_element_by_id("su").click() 用firebug經過查看頁面元素，找到搜索按鈕id屬性值，而後click點擊




2.經過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.經過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.經過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") 這裏經過標籤訂位百度輸入框是會報錯的，由於頁面上input標籤有不少個




5.經過link定位 find_element_by_link_text()
6.經過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 是一種在XML 文檔中定位元素的語言

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)是一種語言，它被用來描述HTML 和XML 文檔的表現

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提供了八種單數定位，一樣也有八種複數定位 定位一組元素取下標，如：find_elements_by_class_name(「xx」)[1]
