在网上/kyle_zhao/archive//02/27/1674819.html，看到这样一篇文章，
JQuery实现智能输入提示（仿机票预订网站）,下载后看了一下，它把查询的城市信息放在了aircity.js文件里。

感觉不太爽，因为大多数情况下，我们会要动态获得这些数据，所以我对它进行了一下改造。。先上图
这是修改后的html文件：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>智能输入提示</title><link rel="stylesheet" type="text/css" href="js/jquery.suggest.css"><script type="text/javascript" src="js/jquery-1.4.2.min.js"></script><script type="text/javascript" src="js/j.dimensions.js"></script><script type="text/javascript" src="js/aircity.js"></script><script type="text/javascript" src="js/j.suggest.js"></script><script type="text/javascript">$(function() {$.ajax({type : "post",url : "<SPAN style="COLOR: #ff0000">1.json</SPAN>",timeout : 20000,error : function() {alert('服务器错误');},async : false,dataType : "json",success : function(data) {var str = "";var str1 = "";$("#arrcity").suggest(<SPAN style="COLOR: #ff0000">data</SPAN>, {hot_list : <SPAN style="COLOR: #ff0000">data</SPAN>,dataContainer : '#arrcity_3word',attachObject : '#suggest'});}});});</script></head><div id="box"><h1>仿机票预定智能输入提示DEMO</h1><input type="hidden" name="arrcity_3word" id="arrcity_3word" value="" /><label for="arrcity">出发城市：</label><input type="text" name="arrcity"id="arrcity" /><div id='suggest' class="ac_results"></div></div></html>
先是用ajax请求从后台获取json字符串，然后传入到页面。由于是例子，json很简单。
{"content1":["","刘德华","LDH","liudehua"],"content2":["","李宇春","lyc","LYC"],"content3":["","张卫健","zwj","ZWJ"]}
主要修改了j.suggest.js的displayItems方法。
