Jquery AutoComplete的使用方法实例

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：

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                     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>
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>

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            Response.Clear();
            Response.Charset = "utf-8";
            Response.Buffer = true;
            this.EnableViewState = false;
            Response.ContentEncoding = System.Text.Encoding.UTF8;
            Response.ContentType = "text/plain";
            Response.Write(GetLikeUserName());
            Response.Flush();
            Response.Close();
            Response.End();
        }
    }
    private string GetLikeUserName()
    {
        string[] str ={ "January", "Ceshi", "jQuery", "josn", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December" };
        StringBuilder sbstr = new StringBuilder();
        sbstr.Append("[");
        for (int i = 0; i < str.Length; i++)
        {
            if (i == str.Length - 1)
            {
                sbstr.Append("{name:'" + str[i] + "',to:'最后中文测试" + i + "'}");
            }
            else
            {
                sbstr.Append("{name:'" + str[i] + "',to:'中文测试" + i + Request.QueryString["q"] + "'},");
            }
        }
        sbstr.Append("]");
        
        return sbstr.ToString();
    }

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。
