I using Selenium Python bindings to find some elements. in some place i need to use execute_script method. Hot to get returned values from executing this script?

So i put:

browser = driver.Chrome() #for example script = "document.getElementById('element')" browser.execute_script(script)

How to receive values into python log or variable from that script? Like element`s ID, text, etc.?

    I had a problem where selenium was not able to find some element but the JavaScript console on chrome found it.

    So I tried adding a "return" string in the execute script method, which in your case would be:

    browser = driver.Chrome() myElement = browser.execute_script("return document.getElementById('element_id')")

    You can also do different operations like you do with Selenium Web-elements.

    Example:

    browser = driver.Chrome() elementList = browser.execute_script("return document.getElementsByClassName('element_class_name')") elementList[0].click() # Clicks the first element from list

    I hope this helps!

      From the js doc (python api can be found there)

      If the script has a return value (i.e. if the script contains a return statement), then the following steps will be taken for resolving this functions return value: - For a HTML element, the value will resolve to a webdriver. WebElement - Null and undefined return values will resolve to null
      - Booleans, numbers, and strings will resolve as is Functions will resolve to their string representation - For arrays and objects, each member item will be converted according to the rules above

      P.S. Why you need to find element using executeScript?
