Solve the problem that extjs API documentation cannot be displayed

Download extjs2.0.2 and want to see its API documentation. However, after opening docs/index.html, the window on the right is always in loading and cannot see the content.
The firebug error is: This . El has no properties
File: // /F:/document/JavaScript/ext-2.0.2/ext-all.js
Line 58

But look at the extjs site on the API Doc is good. Tried to download their website on the ext-all.js, or not.
The final thought is to replace the adapter. Then open docs/index.html and find<ScriptType= "Text/JavaScript"SRC= "../Adapter/EXT/ext-base.js"> </Script>

Replace: < Script Type = "Text/JavaScript" SRC = "../Adapter/jquery. js" > </ Script >
< Script Type = "Text/JavaScript" SRC = ".../Adapter/jquery/ext-jquery-adapter.js" > </ Script >

Refresh docs/index.html in the browser. Everything is OK!
