Highlights a Selenium Webdriver element

highlight_sel_element.py

def highlight(element):
    """Highlights (blinks) a Webdriver element.
    In pure javascript, as suggested by https://github.com/alp82.
    """
    driver = element._parent
    driver.execute_script("""
        element = arguments[0];
        original_style = element.getAttribute('style');
        element.setAttribute('style', original_style + "; background: yellow; border: 2px solid red;");
        setTimeout(function(){
            element.setAttribute('style', original_style);
        }, 300);
    """, element)

I made a simpler version in pure javascript with setTimeout (suggested by https://github.com/alp82).

how do I call this function in ruby selenium webdriver?

i tried: driver.highlight(:css,"input[name='email']")

but it didn't work.

Big up for this trick!

Thanks for great the trick. I started a module that builds on top of this general idea for any nodejs users looking for a similar tool npm / github

Big thanks for this!

Thanks - Is there a license with this code?
