Multi-layered frame or window positioning:
Smart wait:
For a modern web application, there are often frames or windowapplications, which poses a challenge to our positioning.
Sometimes we locate an element, the locator does not have a problem, but has not been able to locate, it is necessary to check whether this element is in a frame ,seelnium webdriver provides a switch_to_frame method, It can be easy to solve this problem.
Frame.html
<Html><Head><MetaHttp-equiv= "Content-type"Content= "Text/html;charset=utf-8"/><Title>frame</Title><ScriptType= "Text/javascript"Async=""Src= "Http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></Script><LinkHref= "Http://netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/css/bootstrap-combined.min.css"Rel= "stylesheet"/><ScriptType= "Text/javascript">$ (document). Ready (function(){});</Script></Head><Body><DivClass= "Row-fluid"><DivClass= "Span10 Well"><H3>frame</H3><IframeId= "F1"Src= "Inner.html"Width= "800", height= "600"></iframe>< Span style= "COLOR: #0000ff" ></div></div> </body><script src = "Http://netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/js/bootstrap.min.js" Span style= "COLOR: #0000ff" >></script></html>
Inner.html
<Html><Head><MetaHttp-equiv= "Content-type"Content= "Text/html;charset=utf-8"/><Title>inner</Title></Head><Body><DivClass= "Row-fluid"><DivClass= "Span6 Well"><H3>inner</H3><IframeId= "F2"Src= "Http://www.baidu.com"Width= "700"Height= "500"></iframe>< Span style= "COLOR: #0000ff" ><a href=" Javascript:alert (' watir-webdriver better thanselenium webdriver; ') " >click</a></div></div ></body></html>
frame.html nested inner.html, two files and our script files are placed in the same directory:
Switch_to_frame ()
To manipulate the above page, the code is as follows:
#Coding=utf-8From seleniumImportWebdriverImportTimeImportOsbrowser =Webdriver. Firefox () File_path =‘file:///' + Os.path.abspath (‘Frame.html‘) Browser.get (File_path) browser.implicitly_wait (30)#First find the ifrome1 (id = f1) browser.switch_to_frame ("F1 ") # Then find the ifrome2 below it (ID =f2) browser.switch_to_frame ( "f2< Span style= "COLOR: #800000" > ")
# Below you can manipulate elements browser.find_element_by_id (" kw" selenium ") browser.find_element _by_id ( "su" ). Click () time.sleep (3 Browser.quit ()
Driver.switch_to_window ()
It is possible to nest not frames, but windows, and true-to-window methods: Switch_to_window
Usage is the same as Switch_to_frame:
Driver.switch_to_window ("Windowname")
Implicitly_wait ()
Careful words will find 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 may be in a time range of intelligent waiting.
