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:

<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:

<span style="font-size:18px;">Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/--> 1 <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></span>


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:

<span style="font-size:18px;">Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/--> 1 <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></span>


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。
