018、元素属性获取 (text、tag_name、get_attribute)

 

一、元素属性获取

　　.text ：获取元素的text属性值
　　.tag_name：  获取元素标签名称
　　.get_attribute() ：获取属性对应的值

 

 

1、.text ：获取元素的 text 属性值  和  .tag_name：  获取元素标签名称

示例代码如下：

# -*- coding:utf-8 -*-
# Author:  Sky
# Email:   2780619724@qq.com
# Time:    2021/8/18 12:25
# Project: day01
# Module:  study_20.py
# Environment: Python3.8.6 , Selenium3 环境 ( 3.141.0 版本)
# Environment: Chrome ( 92.0.4515.131, 正式版本) + chromedriver(92.0.4515.107版本)

from selenium import webdriver
import time

driver = webdriver.Chrome()
driver.get("http://49.235.92.12:8200/users/login/")
time.sleep(3)

# 定位回到首页text
t1 = driver.find_element_by_class_name("index-font").text
print(t1)

# 电话号码text
t2 = driver.find_element_by_xpath("/html/body/header/div/div/ul/li[1]/span").text
print(t2)

# tag_name
tag = driver.find_element_by_id("username").tag_name
print(tag)

driver.quit()

执行结果如下：

D:\SkyWorkSpace\WorkSpace\Web_AutoTest\Temp\day01\venv\Scripts\python.exe D:/SkyWorkSpace/WorkSpace/Web_AutoTest/Temp/day01/ch_002/study_20.py

from selenium import webdriver
import time

driver = webdriver.Chrome()
driver.get("http://49.235.92.12:8200/users/login/")
driver.maximize_window()
time.sleep(3)

# 获取页面上的服务电话
t2 = driver.find_element_by_xpath("/html/body/header/div/div/ul/li[1]/span").text
print(t2)

# 获取所有子孙元素文本
# 服务电话：8888888
t3 = driver.find_element_by_xpath("/html/body/header/div/div/ul/li[1]").text
print(t3)

driver.quit()

执行结果如下：

D:\SkyWorkSpace\WorkSpace\Web_AutoTest\Temp\day01\venv\Scripts\python.exe D:/SkyWorkSpace/WorkSpace/Web_AutoTest/Temp/day01/ch_002/study_20.py

3、获取这个登陆按钮元素的每个属性对应的值

　　<input class="btn btn-green" id="jsLoginBtn" type="submit" value="立即登录 > ">

示例代码如下：

# -*- coding:utf-8 -*-

from selenium import webdriver
import time

driver = webdriver.Chrome()
driver.get("http://49.235.92.12:8200/users/login/")
driver.maximize_window()
time.sleep(3)

btn = driver.find_element_by_id("jsLoginBtn")
btn_value = btn.get_attribute("value")
print(btn_value)
btn_class = btn.get_attribute("class")
print(btn_class)
btn_type = btn.get_attribute("type")
print(btn_type)

driver.quit()

执行结果如下：

D:\SkyWorkSpace\WorkSpace\Web_AutoTest\Temp\day01\venv\Scripts\python.exe D:/SkyWorkSpace/WorkSpace/Web_AutoTest/Temp/day01/ch_002/study_20.py
立即登录 >

4、如何获取输入框的值？

示例代码如下：

# -*- coding:utf-8 -*-
# Author:  Sky

# Environment: Chrome ( 92.0.4515.131, 正式版本) + chromedriver(92.0.4515.107版本)


from selenium import webdriver
import time
driver = webdriver.Chrome()
driver.maximize_window()
driver.get("http://49.235.92.12:8200/users/login/")

# 没输入之前，输入框的值
t1 = driver.find_element_by_id("username").get_attribute("value")
print(t1)

# 输入文本
driver.find_element_by_id("username").send_keys("1234@qq.com")

# 我如何知道刚才输入的内容是成功的
t2 = driver.find_element_by_id("username").get_attribute("value")
print(t2)

driver.quit()

执行结果如下：

D:\SkyWorkSpace\WorkSpace\Web_AutoTest\Temp\day01\venv\Scripts\python.exe D:/SkyWorkSpace/WorkSpace/Web_AutoTest/Temp/day01/ch_002/study_20.py

1234@qq.com

5、.get_attribute() 如果没有这个属性，不会报错， 返回的是None

示例代码如下：

# Environment: Chrome ( 92.0.4515.131, 正式版本) + chromedriver(92.0.4515.107版本)


from selenium import webdriver
import time
driver = webdriver.Chrome()
driver.maximize_window()
driver.get("http://49.235.92.12:8200/users/login/")

# 没输入之前，输入框的值
t1 = driver.find_element_by_id("username").get_attribute("valuexxx")
print(t1)

driver.quit()

执行结果如下：

D:\SkyWorkSpace\WorkSpace\Web_AutoTest\Temp\day01\venv\Scripts\python.exe D:/SkyWorkSpace/WorkSpace/Web_AutoTest/Temp/day01/ch_002/study_20.py
