Python-Selenium-在iframe中导航时遇到的问题

Question

I've been trying to log into a website using selenium. I have the following problem > i manage to open an iframe (it is correctly displayed after i click on the login button) but i've been unable to move into it. I've been trying to find it via it's Id and name but i somehow can't find it...

The line looks like:

driver.switch_to.frame(driver.find_element_by_id("frameid"))

I get an error "no such element". I checked 1000 times the id and it is correct! The frame i want to switch to is not inside another frame.

Any suggestions ?

Answer 1

It seem's that the id is somehow dynamically allocated but always starts with the same characters. I can't use a regex-based search apparently

In this case you can locate it with an XPath and starts-with() function:

frame = driver.find_element_by_xpath("//iframe[starts-with(@id, 'something')]")
driver.switch_to.frame(frame)

Or, with a CSS "begin with" selector :

frame = driver.find_element_by_css_selector("iframe[id^=something]")
driver.switch_to.frame(frame)
