Selenium+Python 调用js操作页面元素

#!/usr/bin/env python

-- coding: utf-8 --

from selenium import webdriver
import os
import time

driver = webdriver.Chrome()
file_path = 'file:///' + os.path.abspath("demo.html")
driver.get(file_path)
time.sleep(2)

#######在页面中直接执行js#################
driver.execute_script('$("#btn1").fadeOut();')
time.sleep(2)

#######在某个已经定位的元素上执行js########
button = driver.find_element_by_class_name('btn')
driver.execute_script('$(arguments[0]).click()', button)
time.sleep(2)
driver.switch_to.alert.accept()
time.sleep(2)

#################调用js代码##############
js = "var q=document.getElementById('username');q.style.border='1px solid red';q.value='PTQA TEST' "
driver.execute_script(js)
time.sleep(2)
js2 = "alert(666);"
driver.execute_script(js2)
time.sleep(2)
driver.switch_to.alert.accept()
time.sleep(2)

######Jquery控制浏览器内嵌div的滚动条 ####
driver.find_element_by_id('btn_myModal').click()
time.sleep(2)
js3 = '$(".modal-body").scrollTop(10000)'
driver.execute_script(js3)
time.sleep(2)
driver.find_element_by_css_selector('button.close').click()
time.sleep(2)

##########Jquery控制浏览器的滚动条 ######
js4 = '$(document).scrollTop(1000)'
driver.execute_script(js4)
time.sleep(5)

driver.close()

复制代码

滚动到页面底部也可以这样

driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")
