Selenium - Webdriver API /ActionChains API

1. Control the browser

1.1 Control the size of the browser window

# Get the size of the current browser driver . get_window_size ( )

# Set the size of the browser in pixels driver .set_window_size ( ' width' , 'height' )

# Get the x,y coordinates of the current window's position relative to Windows driver . get_window_position ( )

# Set the position of the current window for Windows, x,y driver . set_window_position ( 20 , 20 )

# Maximize the current window, no need to pass parameter driver . maximize_window ( )

# Returns the browser handle for the current operation driver .current_window_handle

# Returns all browser handles that open the server driver . window_handles

1.2 Control browser back and forward

# Forward driver.forward ( )

# back driver.back ( )

1.3 Simulate browser refresh

# refresh driver . refresh ( )

2. Simple element operation

2.1 Common methods

#Clear the content of the text input box element . clear()

#Simulate the keyboard to input content into the input box element . send_keys(*value)

#Used to click an element element . click() is provided that it is an object that can be clicked. It and the send_keys(*value) method are the two most commonly used methods in Web page operations

The click() method can not only be used to click a button, it can also click any clickable text, image link, checkbox, radio button, drop-down box

2.2 Common methods of WebElement interface

Often the interesting and required methods of interacting with the page are provided by the WebElement interface

#Imitate the Enter button to submit data element . submit ( )

# According to the label attribute name, get the attribute value element.get_attribute('style')

# Get property element.get_property('id')

# Returns whether the element is visible True or False element.is_displayed()

# Returns whether the element is selected True or False element.is_selected()

# Returns the name of the tag element element.tag_name

# Get the width and height of the current label element . size

# Get the text content of the element element . text

# Get the coordinates of the current element element.location

# 截取图片 element.screenshot()

2.3 其他

执行JavaScript语句 driver.execute_script('JavaScript Commond')

例如通过js来操作滚动条 driver.execute_script('window.scrollTo(0,0);')

三、鼠标操作

在Webdriver 中，鼠标操作的方法封装在ActionChains 类中

引入方式： from selenium.webdriver.common.action_chains import ActionChains

3.1 鼠标右击操作

from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains
# 导入提供鼠标操作的ActionChains
driver = webdriver.Chrome()
driver.get('http://ui.imdsx.cn/uitester/')
driver.maximize_window() #最大化当前窗口
driver.execute_script('window.scrollTo(0,0);')
#执行JavaScript语句，通过js 来操作滚动条
right_click = driver.find_element_by_id('id1')
ActionChains(driver).context_click(right_click).perform()

ActionChains(driver) 
调用ActionChains() 类，将浏览器驱动driver作为参数传入

context_click(right_click)

context_click( )方法用于模拟鼠标右键操作，在调用时需要指定元素定位

perform()
执行所有ActionChains 中存储的行为，可以理解成是对整个操作的提交动作
3.2 鼠标悬停 move_to_element（）

move_to_element（） 方法可以模拟鼠标悬停的动作，其用法与context_click( )相同

dive = driver.find_element_by_css_selector('#a')
ActionChains(driver).move_to_element(dive).perform()
3.3 鼠标双击操作 double_click()

3.4 鼠标拖放操作 drag_and_drop（source,target）
source 鼠标拖动的源元素
target 鼠标释放的目标元素

s = driver.find_element_by_css_selector('#dragger')
t = driver.find_element_by_css_selector('#i1')
ActionChains(driver).drag_and_drop(s,t).perform()

引用方法 ：from selenium.webdriver.common.keys import Keys

# key_down 模拟键盘摁下某个按键 key_up 松开某个按键，与sendkey连用完成一些操作，每次down必须up一次否则将出现异常
ActionChains(driver).key_down(Keys.CONTROL,dom).send_keys('a').send_keys('c').
    key_up(Keys.CONTROL).key_down(Keys.CONTROL,dom1).send_keys('v').key_up(Keys.CONTROL).perform()
