jQuery的Autocomplete（自动完成、自动填充）插件有不少，但比较下来我感觉，还是bassistance.de的JQuery Autocomplete plugin比较强大，我们就来写一些代码感受一下。

jquery-autocomplete配置：

<scripttype="text/javascript"src="/js/jquery-1.4.2.min.js"></script>

<scripttype="text/javascript"src="/js/jquery.autocomplete.min.js"></script>

<linkrel="Stylesheet"href="/js/jquery.autocomplete.css"/>

首先是一个最简单的Autocomplete（自动完成）代码片段：

1 <html xmlns="http://www.w3.org/1999/xhtml"> 
2 <head runat="server"> 
3     <title>AutoComplate</title> 
4     <script type="text/javascript" src="/js/jquery-1.4.2.min.js"></script> 
5     <script type="text/javascript" src="/js/jquery.autocomplete.min.js"></script> 
6     <link rel="Stylesheet" href="/js/jquery.autocomplete.css" /> 
7     <script type="text/javascript"> 
8         $(function() { 
9             var data = "Core Selectors Attributes Traversing Manipulation CSS Events Effects Ajax Utilities".split(" "); 
10 
11             $('#keyword').autocomplete(data).result(function(event, data, formatted) { 
12                 alert(data); 
13             }); 
14         }); 
15     </script> 
16 </head> 
17 <body> 
18     <form id="form1" runat="server"> 
19     <div> 
20         <input id="keyword" /> 
21         <input id="getValue" value="GetValue" type="button" /> 
22     </div> 
23     </form> 
24 </body> 
25 </html>

result方法是jQueryAutocomplete插件里的重要方法，它在用户在选定了某个条目时触发。data参数为选中的数据。

一个稍微复杂的例子，可以自定义提示列表:

1 <html xmlns="http://www.w3.org/1999/xhtml"> 
2 <head runat="server"> 
3     <title>自定义提示</title> 
4     <script type="text/javascript" src="/js/jquery-1.4.2.min.js"></script> 
5     <script type="text/javascript" src="/js/jquery.autocomplete.min.js"></script> 
6     <link rel="Stylesheet" href="/js/jquery.autocomplete.css" /> 
7     <script type="text/javascript"> 
8         var emails = [ 
9             { name: "Peter Pan", to: "[email protected]" }, 
10             { name: "Molly", to: "[email protected]" }, 
11             { name: "Forneria Marconi", to: "[email protected]" }, 
12             { name: "Master <em>Sync</em>", to: "[email protected]" }, 
13             { name: "Dr. <strong>Tech</strong> de Log", to: "[email protected]" }, 
14             { name: "Don Corleone", to: "[email protected]" }, 
15             { name: "Mc Chick", to: "[email protected]" }, 
16             { name: "Donnie Darko", to: "[email protected]" }, 
17             { name: "Quake The Net", to: "[email protected]" }, 
18             { name: "Dr. Write", to: "[email protected]" }, 
19             { name: "GG Bond", to: "[email protected]" }, 
20             { name: "Zhuzhu Xia", to: "[email protected]" } 
21         ]; 
22 
23             $(function() { 
24                 $('#keyword').autocomplete(emails, { 
25                     max: 12,    //列表里的条目数 
26                     minChars: 0,    //自动完成激活之前填入的最小字符 
27                     width: 400,     //提示的宽度，溢出隐藏 
28                     scrollHeight: 300,   //提示的高度，溢出显示滚动条 
29                     matchContains: true,    //包含匹配，就是data参数里的数据，是否只要包含文本框里的数据就显示 
30                     autoFill: false,    //自动填充 
31                     formatItem: function(row, i, max) { 
32                         return i + '/' + max + ':"' + row.name + '"[' + row.to + ']'; 
33                     }, 
34                     formatMatch: function(row, i, max) { 
35                         return row.name + row.to; 
36                     }, 
37                     formatResult: function(row) { 
38                         return row.to; 
39                     } 
40                 }).result(function(event, row, formatted) { 
41                     alert(row.to); 
42                 }); 
43             }); 
44     </script> 
45 </head>
