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：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server">    <title>AutoComplate</title>    <script type="text/javascript" src="Scripts/jquery-1.4.1.min.js"></script>    <script type="text/javascript" src="Scripts/jquery.autocomplete.min.js"></script>    <link rel="Stylesheet" href="Scripts/jquery.autocomplete.css" />    <script type="text/javascript">        $(function () {            var data = "Core Selectors Attributes Traversing Manipulation CSS Events Effects Ajax Utilities".split(" ");            $('#keyword').autocomplete(data).result(function (event, data, formatted) {                alert(data);            });        });    </script></head><body><form id="form1" runat="server">    <div>         <input id="keyword" />         <input id="getValue" value="GetValue" type="button" />    </div></form></body></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:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server">    <title>自定义提示</title>    <script type="text/javascript" src="Scripts/jquery-1.4.1.min.js"></script>    <script type="text/javascript" src="Scripts/jquery.autocomplete.min.js"></script>    <link rel="Stylesheet" href="Scripts/jquery.autocomplete.css" />    <script type="text/javascript">        var emails = [        { name: "Peter Pan", to: "peter@pan.de" },        { name: "Molly", to: "" },        { name: "Forneria Marconi", to: "live@japan.jp" },        { name: "Master <em>Sync</em>", to: "" },        { name: "Dr. <strong>Tech</strong> de Log", to: "" },        { name: "Don Corleone", to: "" },        { name: "Mc Chick", to: "info@donalds.org" },        { name: "Donnie Darko", to: "dd@timeshift.info" },        { name: "Quake The Net", to: "" },        { name: "Dr. Write", to: "" },        { name: "Mc_xueyong", to: "123sao@qq.com" },        { name: "Dota", to: "IceFrog@bug.com" }        ];        $(function () {            $('#keyword').autocomplete(emails, {                max: 12, //列表里的条目数                minChars: 0, //自动完成激活之前填入的最小字符                width: 400, //提示的宽度，溢出隐藏                scrollHeight: 300, //提示的高度，溢出显示滚动条                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                autoFill: false, //自动填充                formatItem: function (row, i, max) {                    return i + '/' + max + ':"' + row.name + '"[' + row.to + '}';                },                formatMatch: function (row, i, max) {                    return row.name + row.to;                },                formatResult: function (row) {                    return row.to;                }            }).result(function (event, row, formatted) {                alert(row.to);            });        });    </script></head><body><form id="form1" runat="server">    <div>         <input id="keyword" />         <input id="getValue" value="GetValue" type="button" />    </div></form></body></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。<\p>
