How to change the text of a span that acts like a button

问题

I am working on writing automation tests for a custom web application. I am running into a problem where I can't change the text of a span. I have tried using driver.execute_script but have had no luck. (It would really help if I knew javascript better) As far as I know you can't click a span and the list is populated as a list of . What is the best way to change this text?

回答1:

You need to set the innerHTML using execute_script():

driver.execute_script('arguments[0].innerHTML = "New value";', element)

where element should point to your span element, could be:

element = driver.find_element_by_css_selector('div.file-wrapper span.k-dropdown span.k-input')
