In this post we will be talking about Javascript DOM and BOM and its usage behind the scenes in Selenium.
Javascript
JavaScriptis a high-level, dynamic, untyped, and interpreted programming language
Javascript is one of the three essential technologies of World Wide Web content production and majority of site has Javascript running in it.
Javascript runs without any plugins
Javascript and selenium
As we all know Selenium WebDriver behind the scenes converts the client code (language bindings) to its equivalent Javascript and injects in browsers like IE, Chrome, Firefox etc, JS is thus a key player in Selenium.
We can perform whatever operation selenium performs using Javascript itself.
To prove the concept, we need to understanding following Javascript libraries
Javascript HTML Document Object Model
Javascript Browser Object Model
E.G of Javascript Document Object Model
To get title of the document
Document.title
To get ready state of page (fully loaded)
Document.readyState
Finding an element with Id
Document.getElementById()
E.G of Javascript Browser Object Model
Opening a new window
window.Open
To go back of page
window.history.back()
To get the origin of the page
window.location
