Personal notes, excerpt from the insect Master Python selenum, for personal reference only

1. Installation:

Pip Install Selenium

Download Webdriver
# Webdriver downloaded and placed in the Python home directory 1.chromedriver:https://code.google.com/p/chromedriver/downloads/List2. The driver of Firefox driver geckodriver:https://github.com/mozilla/geckodriver/releases/3.ie iedriver:http://www.nuget.org/ packages/selenium.webdriver.iedriver/

2. Basic use

 from Import  == webdriver. Chrome () browser.set_window_size(480, +)  # parameter number is pixel point browser.maximize_window ()  # maximize the browser display #

3. Element positioning

Move_to_element (Ele). Perform ()

4, the operation of objects, webelement common methods, summary

Action object:

• · Click on Object
• · Send_keys analog key input on the object
• · Clear clears the contents of the object, if possible

Webelement Other common methods:

• · Text gets the literal of the element
• · Submit Form
• · Get_attribute Getting property values

5. Positioning frame

Multi-layered frame or window positioning:

• Switch_to_frame ()
• Switch_to_window ()

Smart wait:

• Implicitly_wait ()

6, using selenium Webdriver call JS

Invoking the JS method

• Execute_script (script, *args)

Synchronously executes JavaScript in the current window/frame

Script: Execution of JavaScript.

* Parameters: Applies to any JavaScript script.

Use:

Driver.execute_script (' Document.title ')

7, selenium the location of the drop-down box information, as well as the handling of the warning prompt box

This section focuses on

• Handling drop-down boxes
• Switch_to_alert ()
• Accept ()

8, through the JS control scroll bar to the bottom of the window

js="var q=document.getelementbyid (' id '). scrolltop=10000"driver.execute_script (JS ) JS="var q=document.documentelement.scrolltop=10000"driver.execute_script ( JS)

9, Analog keyboard key operation

• L Keyboard Key Usage
• L Keyboard Combination Key Usage
• L Send_keys () input Chinese operation error problem

 fromSelenium.webdriver.common.keysImportKeys#need to introduce the keys packagedriver.find_element_by_id ("user_name"). Send_keys (Keys.tab) driver.find_element_by_id ("user_pwd"). Send_keys (Keys.enter) driver.find_element_by_id ("kw"). Send_keys (Keys.control,'a') driver.find_element_by_id ("kw"). Send_keys (Keys.control,'C') driver.find_element_by_id ("kw"). Send_keys (Keys.control,'v') Send_keys (U"Enter Chinese")

10. Operation of Cookies via Webdirver

• Driver.get_cookies () Get cookie information
• Add_cookie (COOKIE_DICT) Adding session information to cookies
• Delete_cookie (name) delete a specific (partial) cookie
• Delete_all_cookies () Delete all Cookies

11, Selenium Webdriver Mouse event usage

Actionchains class

• Context_click () Right-click
• Double_click () Double-click
• Drag_and_drop () drag
