ExtJS Dynamically creating components

J is the code that dynamically creates the DOM:

Or

Eval has a background organization code, the front desk

=======================

Dynamic creation of the ExtJS component:

Most of the time in the program you need to create compliant components in the background based on business logic, and then we have to set up the representation variables in the background.

The foreground page is created dynamically, and the component of the page is refreshed when it is created, otherwise it is not displayed.

A common approach:

Dolayout: Re-layout the component-that is, refresh

El: Gets the HTML elements of the component---component rendering will have these elements later

OWNERCT: Gets the container of the component------This method is important

Findbytype: Get the component of the development type

gettarget: Getting a Component object on an event
