Ext JS 实现建议词模糊动态搜索功能

代码：

new Ext.form.ComboBox({
store: new Ext.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)
{
var no = Ext.get("querynodesid").dom.value;
findByKeyWordFiler2(no);
}
}
}
})

参数说明：

queryParam: ‘VehicleNo‘,参数为输入的值 会以VehicleNo参数传入后台，可自定义;

test.ashx? 返回的参数格式为[{"VehicleNo":"00001","phoneNum":"000002"},{},{}];

‘select‘ 为当选择某个数据的时候需要执行的回调;

这种方法适用数据量小的搜索，如果数据量比较大的搜索可能会影响到性能
