ExtJs syntax for document.getElementById()

The getElementById() method accesses the first element with the specified id. It can be a div tag or any other HTML element with the specified id. After you get reference to the element its easy to get and set values. So how do you achieve the same thing in ExtJs. It's pretty easy in ExtJs as well.
