selenium Webdriver自动化测试之执行JavaScript脚本

WebDriver提供了execute_script()方法来执行JavaScript代码

具体DOM操作使用方法见之前写的一篇博文：https://www.cnblogs.com/feng0815/p/8215768.html

关于Webdriver自动化测试之执行JavaScript脚本可直接参考下面代码

import os


from selenium import webdriver




class Base:

def setup_class(self):

# option = webdriver.ChromeOptions()

# option.add_experimental_option('w3c', False)

# self.driver = webdriver.Chrome(options=option)

browser = os.getenv('browser')

if browser == 'firefox':

self.driver = webdriver.Firefox()

elif browser == 'headless':

self.driver = webdriver.phantomjs()

else:

self.driver = webdriver.Chrome()

self.driver.maximize_window()

self.driver.implicitly_wait(5)

    self.driver.quit()

    self.driver.quit()

上面代码为演示代码中from test_selenium.base import Base 导入的代码

from time import sleep


from test_selenium.base import Base




class TestJS(Base):

# 百度搜索演示

def test_js(self):

self.driver.get('https://www.baidu.com')

self.driver.find_element_by_id('kw').send_keys('selenium测试')

element = self.driver.execute_script('return document.getElementById("su")')

element.click()  # 点击搜索

sleep(2)

self.driver.execute_script('document.documentElement.scrollTop=10000')  # 页面向下滑动10000个像素

sleep(2)

self.driver.find_element_by_xpath('//*[@id="page"]/div/a[10]').click()  # 点击下一页

sleep(2)

self.driver.execute_script('document.documentElement.scrollTop=10000')  # 页面向下滑动10000个像素

sleep(2)

for code in [

'return document.title', 'return JSON.stringify(performance.timing)'

]:

print(self.driver.execute_script(code))

# print(self.driver.execute_script('return document.title;return JSON.stringify(performance.timing)'))

# JSON.stringify() 方法用于将 JavaScript 值转换为 JSON 字符串。

# performance.timing  加载和使用当前页面期间发生的各种事件的性能计时信息。

常用JavaScript脚本

driver.execute_script("document.body.style.zoom='0.5'") #网页缩小
driver.execute_script("document.body.style.zoom='1.7'") #网页放大
driver.executeScript("window.scrollTo(window.pageXOffset,document.body.scrollHeight)"); #滑动到页面最底部
driver.executeScript("window.scrollTo(window.pageXOffset, 0)");#滑动到页面最顶部
driver.executeScript("arguments[0].scrollIntoView(false);", driver.findElement(by));#上下滑动使元素和窗口底部对齐
driver.executeScript("arguments[0].scrollIntoView(true);", driver.findElement(by));  #上下滑动使元素和窗口顶部对齐
driver.executeScript("window.scrollTo(document.body.scrollWidth, window.pageYOffset)") #水平滑动到页面最右边
