[Jquery] Jquery AutoComplete的使用方法实例

jQuery的Autocomplete（自动完成、自动填充）插件

jquery-autocomplete配置：

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jQuery Autocomplete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: "peter@pan.de" },
10             { name: "Molly", to: "molly@yahoo.com" },
11             { name: "Forneria Marconi", to: "live@japan.jp" },
12             { name: "Master <em>Sync</em>", to: "205bw@samsung.com" },
13             { name: "Dr. <strong>Tech</strong> de Log", to: "g15@logitech.com" },
14             { name: "Don Corleone", to: "don@vegas.com" },
15             { name: "Mc Chick", to: "info@donalds.org" },
16             { name: "Donnie Darko", to: "dd@timeshift.info" },
17             { name: "Quake The Net", to: "webmaster@quakenet.org" },
18             { name: "Dr. Write", to: "write@writable.com" },
19             { name: "GG Bond", to: "Bond@qq.com" },
20             { name: "Zhuzhu Xia", to: "zhuzhu@qq.com" }
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                     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>
46 <body>
47     <form id="form1" runat="server">
48     <div>
49         <input id="keyword" />
50         <input id="getValue" value="GetValue" type="button" />
51     </div>
52     </form>
53 </body>
54 </html>

formatItem、formatMatch、formatResult是自定提示信息的关键。

formatItem作用在于可以格式化列表中的条目，比如我们加了“I”，让列表里的字显示出了斜体。

formatMatch是配合formatItem使用，作用在于，由于使用了formatItem，所以条目中的内容有所改变，而我们要匹配的是原始的数据，所以用formatMatch做一个调整，使之匹配原始数据，

formatResult是定义最终返回的数据，比如我们还是要返回原始数据，而不是formatItem过的数据。

MVC下场景应用

后台代码：

//类对象

public class EmailObj   {       public string name { get; set; }       public string to { get; set; }   }

//action方法：

public ActionResult get(string q)       {           var emails = new List<EmailObj>(){               new EmailObj(){ name = "Peter Pan", to= "peter@pan.de" },              new EmailObj(){ name= "Molly", to= "molly@yahoo.com" },              new EmailObj(){ name= "Forneria Marconi", to= "live@japan.jp" },              new EmailObj(){ name= "Master Sync", to= "205bw@samsung.com" },              new EmailObj(){ name= "Dr. Tech de Log", to= "g15@logitech.com" },              new EmailObj(){ name= "Don Corleone", to= "don@vegas.com" },              new EmailObj(){ name= "Mc Chick", to= "info@donalds.org" },              new EmailObj(){ name= "Donnie Darko", to= "dd@timeshift.info" },              new EmailObj(){ name= "Quake The Net", to= "webmaster@quakenet.org" },              new EmailObj(){ name= "Dr. Write", to= "write@writable.com" },              new EmailObj(){ name= "GG Bond", to= "Bond@qq.com" },              new EmailObj(){ name= "Zhuzhu Xia", to= "zhuzhu@qq.com" }          };           emails = emails.Where(c => c.to.ToLower().Contains(q.ToLower().TrimEnd())).ToList();           var res = JsonConvert.SerializeObject(emails);           res = res.Replace("},", "}
").TrimStart('[').TrimEnd(']');           return Json(res, JsonRequestBehavior.AllowGet);       }
