Selenium-webdriver (Python) (vii) Multi-layer frame or window positioning

This section knowledge points:

Positioning of a multi-tier frame or window:

Switch_to_frame ()

Switch_to_window ()

Smart wait:

Implicitly_wait ()

For a modern web application, there are often frames or Windows (window) applications, which poses a challenge to our positioning.

Sometimes we locate an element, the locator is not a problem, but it is not fixed, this time we have to check whether this element is in a frame, Seelnium Webdriver provides a switch_to_frame method, can easily solve this problem.

Frame.html

 
Inner.html
 
 
Driver.switch_to_window ()
 
It is possible to nest not the frame, but the window, and the true method of the window: Switch_to_window
 
Usage is the same as Switch_to_frame:
 
Driver.switch_to_window ("Windowname")
 
Implicitly_wait ()
 
Careful words will find that the above example has browser.implicitly_wait (30), its usage should be more intelligent than time.sleep (), the latter can only choose a fixed time waiting, the former can be in a time range intelligent waiting.
