Jquery AutoComplete自动完成的使用方法实例

jquery-autocomplete配置：
<script type="text/javascript" src="/js/jquery-1.4.2.min.js"></script>
<script type="text/javascript" src="/js/jquery.autocomplete.min.js"></script>
<link rel="Stylesheet" href="/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="/js/jquery-1.4.2.min.js"></script> 
<script type="text/javascript" src="/js/jquery.autocomplete.min.js"></script> 
<link rel="Stylesheet" href="/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 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:

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="/js/jquery-1.4.2.min.js"></script> 
<script type="text/javascript" src="/js/jquery.autocomplete.min.js"></script> 
<link rel="Stylesheet" href="/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 + '/' + 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。
