Ext Msg 的惯用方法

	Ext.onReady(function(){
		//Ext.Msg.alert("title","Hello World");
		
		//带多个按钮的弹框 
		/*
		Ext.Msg.show({
			title:"Miltion",
			msg:"hava you seen my stapler?",
			buttons:{
				yes:true,
				no:true,
				cancel:true
			}
		});
		*/
		
		//自定义按钮显示内容 
		/*Ext.Msg.show({
			title:"Miltion",
			msg:"hava you seen my stapler?",
			buttons:{
				yes:'mayBe',
				no:'no',
				cancel:'cancel'
			},
			fn:function(btn){
				//这个会弹出yes、no、cancel，而不是maybe等 
				Ext.Msg.alert("you clicked :", btn);
			}
		})*/;
		
		//prompt、wait的使用
		/*Ext.Msg.show({
			title:"Miltion",
			msg:"hava you seen my stapler?",
			buttons:{
