简单使用方法：
复制代码 代码如下:
<html>
<head>
<title>JQuery-Cookie插件</title>
<script type="text/javascript" src="https://www.jb51.net/jquery-1.4.js"></script>
<script type="text/javascript" src="https://www.jb51.net/jquery.cookie.js"></script>
</head>
<body>
<a href="#">设置cookie1</a><br>
<a href="#">设置cookie2</a><br>
<a href="#">获取cookie</a><br>
<a href="#">删除cookie</a><br>
</body>
</html>
<script type="text/javascript">
$(function(){
var COOKIE_NAME = 'test_cookie';
//设置cookie，通过时间间隔
$('a').eq(0).click(function() {
$.cookie(COOKIE_NAME, 'test', { path: 'https://www.jb51.net/', expires: 1 });
return false;
});
// 设置cookie，到期时间
$('a').eq(1).click(function() {
var date = new Date();
date.setTime(date.getTime() + (1 * 24 * 60 * 60 * 1000));
$.cookie(COOKIE_NAME, 'test', { path: 'https://www.jb51.net/', expires: date });
return false;
});
// 获取 cookie
$('a').eq(2).click(function() {
alert($.cookie(COOKIE_NAME));
return false;
});
// 删除cookie
$('a').eq(3).click(function() {
$.cookie(COOKIE_NAME, null, { path: 'https://www.jb51.net/' });
return false;
});
});
</script>
插件的源代码也很简单：
复制代码 代码如下:
jQuery.cookie = function(name, value, options) {
if (typeof value != 'undefined') { // name and value given, set cookie
options = options || {};
if (value === null) {
value = '';
options.expires = -1;
}
var expires = '';
if (options.expires && (typeof options.expires == 'number' || options.expires.toUTCString)) {
var date;
if (typeof options.expires == 'number') {
date = new Date();
date.setTime(date.getTime() + (options.expires * 24 * 60 * 60 * 1000));
} else {
date = options.expires;
}
expires = '; expires=' + date.toUTCString();
}
var path = options.path ? '; path=' + (options.path) : '';
var domain = options.domain ? '; domain=' + (options.domain) : '';
var secure = options.secure ? '; secure' : '';
document.cookie = [name, '=', encodeURIComponent(value), expires, path, domain, secure].join('');
} else {
var cookieValue = null;
if (document.cookie && document.cookie != '') {
var cookies = document.cookie.split(';');
for (var i = 0; i < cookies.length; i++) {
var cookie = jQuery.trim(cookies[i]);
if (cookie.substring(0, name.length + 1) == (name + '=')) {
cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
break;
}
}
}
return cookieValue;
}
};
