jquery-autocomplete配置：
<script type="text/javascript" src="https://www.jb51.net/js/jquery-1.4.2.min.js"></script>
<script type="text/javascript" src="https://www.jb51.net/js/jquery.autocomplete.min.js"></script>
<link href="https://www.jb51.net/js/jquery.autocomplete.css" />
首先是一个最简单的Autocomplete（自动完成）代码片段：
复制代码 代码如下:
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>AutoComplate</title>
<script type="text/javascript" src="https://www.jb51.net/js/jquery-1.4.2.min.js"></script>
<script type="text/javascript" src="https://www.jb51.net/js/jquery.autocomplete.min.js"></script>
<link href="https://www.jb51.net/js/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 runat="server">
<div>
<input />
<input 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:
复制代码 代码如下:
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>自定义提示</title>
<script type="text/javascript" src="https://www.jb51.net/js/jquery-1.4.2.min.js"></script>
<script type="text/javascript" src="https://www.jb51.net/js/jquery.autocomplete.min.js"></script>
<link href="https://www.jb51.net/js/jquery.autocomplete.css" />
<script type="text/javascript">
var emails = [
{ name: "Peter Pan", to: "peter@pan.de" },
{ name: "Molly", to: "molly@yahoo.com" },
{ name: "Forneria Marconi", to: "live@japan.jp" },
{ name: "Master <em>Sync</em>", to: "205bw@samsung.com" },
{ name: "Dr. <strong>Tech</strong> de Log", to: "g15@logitech.com" },
{ name: "Don Corleone", to: "don@vegas.com" },
{ name: "Mc Chick", to: "info@donalds.org" },
{ name: "Donnie Darko", to: "dd@timeshift.info" },
{ name: "Quake The Net", to: "webmaster@quakenet.org" },
{ name: "Dr. Write", to: "write@writable.com" },
{ name: "GG Bond", to: "Bond@qq.com" },
{ name: "Zhuzhu Xia", to: "zhuzhu@qq.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 + 'https://www.jb51.net/' + 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 runat="server">
<div>
<input />
<input 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。
