What could be the reason for the empty value of driver_execute?

I'm attempting to input text into a textfield using code.

binary = FirefoxBinary("C:\Program Files\Mozilla Firefox\Firefox.exe")

driver = webdriver.Firefox(firefox_binary=binary)

text = 'sending something to the text area'

input_field = driver.find_element_by_css_selector('.trumbowyg-editor')

input_field.clear()

driver.execute_script("arguments[0].value = arguments[1];", input_field, 'sending something to the text area')

However, this approach doesn't seem to work as intended. There are no errors, but nothing happens.

I then tried the following:

binary = FirefoxBinary("C:\Program Files\Mozilla Firefox\Firefox.exe")

driver = webdriver.Firefox(firefox_binary=binary)

text = 'sending something to the text area'

input_field = driver.find_element_by_css_selector('.trumbowyg-editor')

input_field.clear()

driver.send_keys(text)

This method worked, but I prefer sending text with JavaScript code for its faster execution compared to driver.send_keys().

Answer №1

When using Python binding with Selenium, the approach is similar to Java binding. The script executor in Python expects a string that contains JavaScript code which can be executed in the browser console to achieve the desired outcome.

In this scenario, simply passing the input field (presumably a Python object) to the script executor will not suffice. What should be passed instead is:

driver.execute_script('document.getElementsByClassName("trumbowyg-editor")[0].se‌​tAttribute("value", arguments[0]);','sending something to the text area')

This indicates that element search must also be done within the script itself.
