EXT的combobox的store动态加载固定DATA

var form = Ext.create("Ext.form.FormPanel", {
					columnWidth:.2,
					layout:'form',
					items:{
						id:'flowTypeId',
						xtype:'lovcombo',
						hiddenName:'test',
						fieldLabel:"test",
						triggerAction:"all",
	    	    		lazyRender : true,
	    	    		editable: false,
	    	    		allowBlank : true,
	    	    		mode:"local",
	    	    		displayField:"name",
	    	    		valueField:"id",
	    	    		store : new Ext.data.ArrayStore({
	    	    		fields:['id','name'],
	    	    		data:[[1,"同城"],[2,"区内跨市"],[8,"跨大区"],[7,"大区内跨分拨区"],[6,"分拨区内跨板块"]]	
	    	    		}),
	    	    		showSelectAll:true,
	    	    		emptyText:"全部"
					}
				});

如果需要重新加载：

先获取到对应得store

调用 store.loadData([1,"同城"],[2,"区内"]);就可以对下拉选项进行修改
