About ExtJS 學習之佈局

Ext.namespace("FirstDay.First.Index");

FirstDay.First.Index.LeftPanel = function () { };
Ext.extend(FirstDay.First.Index.LeftPanel, Ext.form.FormPanel, {});

FirstDay.First.Index.MainPanel = function () { };
Ext.extend(FirstDay.First.Index.MainPanel, Ext.form.GridPanel, {});

FirstDay.First.Index.Page = function () { };
Ext.extend(FirstDay.First.Index.Page, Ext.Viewport, {});

Ext.onReady(function () { });

首先爲畫面聲明：NameSpace;
然後寫清楚有幾個Panel；
然後將Panel放入Page中；
然後Ext.onReady(function(){});進行初始化。
