source：是远程请求地址，请求返回的格式如下：

Center

当你输入关键词时，插件会根据你设置的minLength的限制开始向URL请求，注意URL中会自动添加term参数，如下：

http://localhost:52865/handler/CommonHandler.ashx?&term=k

当你进行上下选择的时候，默认会选择value到input输入框，在select事件中，添加如下代码：

select: function (event, ui) { event.preventDefault(); $("#birds").val(ui.item.label); }, focus: function (event, ui) { event.preventDefault(); $("#birds").val(ui.item.label); }
