Selenium moving further

Today I will go over some advanced tips for how to interact with elements using javascript and combine selenium with other tools.

I. Work with web elements by JavaScript in Selenium

For more details, you can refer to this javascript-selenium-webdriver

In general there are two ways to call javascript execute from selenium:

Execute script:

element = driver.execute_script(script_string, *args)
element = driver.execute_async_script(script_string,*args)

Notes:

If you want to get element value, your script should have ‘return’ like : ‘return arguments[0].shadowRoot’

• get element by id:

document.getElementByID('{id}')

• get elements by class name:

document.getElementsByClassName('{className}')

• get elements by selector:

document.querySelector('{selectorName}')
