selenium学习：简单元素操作

WebDriver中常用方法：

clear() 清除文本

send_keys(*value) 模拟按键输入

click() 单机元素

1. 网站的登陆

from selenium import webdriverfrom time import *driver = webdriver.Chrome()url = "https://login.huawei.com/login/?redirect=http%3A%2F%2Fw3.huawei.com%2Fnext%2Findexa.html"print('new access %s' %(url))driver.get(url)driver.find_element_by_id('uid').clear()driver.find_element_by_id('uid').send_keys("c00358145")sleep(3)driver.find_element_by_id('password').clear()driver.find_element_by_id('password').send_keys("&CTT1106648034")driver.find_element_by_class_name('btn').click()sleep(3)driver.quit()2.WebElement接口常用的方法submit（）方法用于提交表单from selenium import webdriverfrom time import *driver = webdriver.Chrome()url = "https://www.baidu.com"print('new access %s' %(url))driver.get(url)driver.find_element_by_id('kw').clear()driver.find_element_by_id('kw').send_keys("c00358145")sleep(3)driver.find_element_by_id('kw').submit()sleep(3)driver.quit()

定位搜索框通过submit提交搜素框的内容，达到点击搜素按钮的效果，有时候可以同click()函数交换使用

方法：size() 返回元素的尺寸

text() 获取元素的文本

get_attribute(name)获取属性的值

is_displayed（） 设置该元素首付用户可见

from selenium import webdriver

from time import *

driver = webdriver.Chrome()

url = "https://www.baidu.com"

print('new access %s' %(url))

driver.get(url)

size = driver.find_element_by_id('kw').size

print('size%s' %size)

text = driver.find_element_by_xpath("//*[@id='u1']/a[1]").text

print('text%s' %text)

attribute = driver.find_element_by_id('kw').get_attribute('type')

print('%s' %attribute)

sleep(3)

driver.quit()
