java + selenium-- open multiple windows, and the window switching - Method a

At first to explain what is the handle, sometimes the browser window handle, also known as windows id, a better understanding of English words.

 

You open a browser, you open a tab, it generated a id, the id until you close the tab will disappear.

If you open more than one tab in a browser, there are more windows id, why do you close one tab, but does not affect the display of the other tab, this is the role of the id.

 

This article is to describe how to get a handle browser form or call the number for the driver to switch back to prepare for instance between multiple forms.

Let's take a look at the browser only open a tab, that is, when only a windows handle, print out the handle out.
================================================== ================================================== ======

 

Print results like this: CDwindow-e3655cc7-5cc1-42cc-a3d0-0d6339d1cfab

The id is every time you start changing, so, you print out the print and I certainly different.

 

Next, look at two tab, print out two windows to handle, use getWindowsHandles () method.
