Ext JS 是怎样实现建议词模糊动态搜索功能的

newExt.form.ComboBox({

 store:newExt.data.JsonStore({

 idProperty:'VehicleNo',

 url:'../ajax/test.ashx,

 fields: ['VehicleNo', 'phoneNum']

 }),

 id:'querynodesid',

 emptyText:'快速检索',

hiddenName: 'VehicleNo',

 displayField: 'VehicleNo',

 valueField: 'VehicleNo',

 queryParam: 'VehicleNo',

 forceSelection: true,

 hideTrigger: true,

 queryDelay: 500,

 width:100,

 enableKeyEvents: true,

 minChars: 1,

 mode: 'remote',

 listeners: {

 'select': {

 fn:function(combo, record, index)

 {

 varno = Ext.get("querynodesid").dom.value;

 findByKeyWordFiler2(no);

 }

 }

 }

 })
