EXT getcmp Usage

• The getcmp method is used to obtain an ext component, which is an object of component or its subclasses that have been initialized in the page.
• The getcmp method is actually a shorthand form of the Ext.ComponentMgr.get method.

There is only one parameter in the GETCMP method, which is the ID of the component. For example, the following code:

Ext.onready (function () {            var h=new ext.panel ({            ID: "H2",            title: ",            renderto:" Hello ",            width:300 ,            height:200});            EXT.GETCMP ("H2"). Settitle ("new title");});

In the code, we use EXT.GETCMP ("H2"). To get the component with ID H2 and call its Settitle method to set the caption of the panel.
