ExtJs combobox数据

local比较简单，后台返回的数据也可以是纯数组或者包含对象数组，这点找了很久都没有例子，因为local模式直接给store赋值为二维数组是可行的，因此肯定也支持后台纯数组的获取，尝试了多次之后终于出了效果。原来是对store认识不够深刻，觉得后台返回的数据既然是二维数组，就直接用了ArrayStore，返回[[],[]]形式，前后都没报错，就是出不来。后来将render设置为ArrayReader，一切ok了。

 

• 纯数组

 

   store

window.nameStore = new Ext.data.Store({
				proxy : new Ext.data.HttpProxy({
							url : webRoot + "mtc.do?m=selectStaffs2"
						}),
				reader : new Ext.data.ArrayReader({
							fields : ['id', 'name'],
							id:0
						})
			});

 

  ui

 

{
							xtype : 'combo',
							fieldLabel : '姓名',
							name : 'name',
							anchor : '100%',
							hiddenName : "name",
							triggerAction : "all",
							store : nameStore,
							valueField : 'id',
							displayField : 'name'
						}

• 对象数组

store

 

window.nameStore = new Ext.data.Store({
				proxy : new Ext.data.HttpProxy({
							url : webRoot + "mtc.do?m=selectStaffs"
						}),
				reader : new Ext.data.JsonReader({
							fields : ['id', 'name'],
							root:'root'
