If locating the element fails （ Throw out NoSuchElementException）, Investigate web page source code , Find this element in a frame or iframe The child page under the marked element （html Mark ） in , Then you need to switch Frame.
Switching method I ： Use frame or iframe Of the marked element id or name Attribute values as switching conditions
switch_to.frame() Switch the currently located subject to frame/iframe The embedded page of the form
switch_to.default_content() Jump back to the outermost page
driver.switch_to.default_content()
driver.switch_to.frame("MAINPAGE")

Two 、 Switch windows
There are multiple windows on the page , however selenium The default focus is only on all elements in the main window , Do not switch windows , You cannot manipulate elements in a window other than the main window .
Each window has a unique handle value , Then we can complete the window switching operation through the handle value
Method ：
1）、driver.current_window_handle ( Get the current handle value )
2）、driver.window_handles （ Get the current by driver Start all window handles ）
3）、driver.switch_to.window(handle) —> Switch windows
from selenium import webdriver
driver = webdriver.Chrome()
driver.get('file:///D:/%E6%A1%8C%E9%9D%A2/page/%E6%B3%A8%E5%86%8C%E5%AE%9E%E4%BE%8B.html')
driver.find_element_by_id('ZCB').click()
# 1). Switch window operation ,driver.window_handles obtain driver All window handles started
handles = driver.window_handles
# 2). Switch window work
driver.switch_to.window(handles[-1])
driver.find_element_by_id('userB').send_keys('admin9')
driver.quit()
