ExtJS Study notes (1)---EXTJS installation and its use

Download the ExtJS 3.2 SDK from the official website, which contains detailed instructions, documentation, examples, and other files for code dependencies. Among them, the adapter and resources files are necessary for the normal operation of Ext, and others are only used during the development process.

Adapter: Files that support the use of Ext and other code libraries

Build: Files for customizing Build Ext-all.js

Docs: Document Center (normal access only when running on the server)

Examples: A number of impressive and insightful examples

Resources:ext dependent files, such as CSS and pictures

All code for Source:ext

Before using EXT, we need to introduce the library file of ext in the page now, in order to achieve this, we need to introduce the SDK file just downloaded in the head tag area of the HTML page.

The reference path of the Ext file must be correct and is the relative path to the HTML page. These files must be introduced once in a sequential order.
Main CSS files in 1.ext-all.css ext
2. External JS library files can be introduced if necessary
3.ext-base.js Ext Code Library "adapter"
4.ext-all.js or ext-all-debug.js main ext code library file
5. Introduce the theme file in this location, or it can be referenced anywhere after the introduction of the main ext CSS file.

The prerequisite knowledge is ready and the first ExtJS page has been written.

Program:
The effect is very good, and the dialog box is free to drag, of course, confined to the area of the page, because this is not a real dialog box, but a series of div tags and pictures of the combination of simulation. In this way, the foreground of HTML is very good.
