Second, code implementation

. 1  from Selenium Import the webdriver
 2  
. 3 DR = webdriver.Chrome ()
 . 4 dr.implicitly_wait (10 )
 . 5 dr.get ( ' HTTP: // XXXXXXXXXXX ' )
 . 6  
. 7  # positioned to the frame element 
. 8 frame dr.find_element_by_xpath = ( ' XXXXX ' )
 . 9 dr.switch_to.frame ( ' WebElement objects ' )
 10  
. 11  # Back outermost page 
12 is  dr.switch_to.default_content ()
 13 is  
14  # returns the frame layer
15 dr.switch_to.parent_frame('webelement对象')
16 
17 dr.quit()
