EXT 2.3 结合 jquery 1.2.6
adapter/ext/ext-base.js换成adapter/jquery/ext-jquery-adapter.js，并在之前引入JQuery
< script type="text/javascript" src="../../adapter/jquery/jquery.js" >< /script >< script type="text/javascript" src="../../adapter/jquery/ext-jquery-adapter.js" >< /script >< script type="text/javascript" src="../../ext-all.js" >< /script >
