JavaScript中jQuery写入读取Cookie插件

寻找了下关于jQuery操作cookie的插件,大概的使用方法如下
example $.cookie('the_cookie', 'the_value');
设置cookie的值
example $.cookie('the_cookie', 'the_value', {expires: 7, path: '/', domain: 'jquery.com', secure: true});
新建一个cookie 包括有效期 路径 域名等
example $.cookie('the_cookie', 'the_value');
新建cookie
example $.cookie('the_cookie', null);
删除一个cookie


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(); // use expires attribute, max-age is not supported by IE
}
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 { // only name given, get cookie
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]);
// Does this cookie string begin with the name we want?
if (cookie.substring(0, name.length + 1) == (name + '=')) {
cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
break;
}
}
}
return cookieValue;
}
};

然后看了下Discuz!中对cookie的操作方法
如下,发现少了个遍历用;分割的数组的处理

function getcookie(name) {
var cookie_start = document.cookie.indexOf(name);
var cookie_end = document.cookie.indexOf(";", cookie_start);
return cookie_start == -1 ? '' : unescape(document.cookie.substring(cookie_start + name.length + 1, (cookie_end > cookie_start ? cookie_end : document.cookie.length)));
}
function setcookie(cookieName, cookieValue, seconds, path, domain, secure) {
var expires = new Date();
expires.setTime(expires.getTime() + seconds);
document.cookie = escape(cookieName) + '=' + escape(cookieValue)
+ (expires ? '; expires=' + expires.toGMTString() : '')
+ (path ? '; path=' + path : '/')
+ (domain ? '; domain=' + domain : '')
+ (secure ? '; secure' : '');
}
