摘要: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 = $.extend({}, options); // clone object since it's unexpected behavior if the expired property were changed 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 } // NOTE Needed to parenthesize options.path and options.domain // in the following expressions, otherwise they evaluate to undefined // in the packed version for some reason... 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; } };

脚本宝典小编觉得挺不错的,现在分享给大家,也给大家做个参考,希望能帮助你少写一行代码,多一份安全和惬意。

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 = $.extend({}, options); // clone object since it's unexpected behavior if the expired property were changed
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
}
// NOTE Needed to parenthesize options.path and options.domain
// in the following expressions, otherwise they evaluate to undefined
// in the packed version for some reason...
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;
}
};

使用方法
jQuery操作cookie的插件,大概的使用方法如下
$.cookie('the_cookie'); //读取Cookie值
$.cookie('the_cookie', 'the_value'); //设置cookie的值
$.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
$.cookie('the_cookie', 'the_value'); //新建cookie
$.cookie('the_cookie', null); //删除一个cookie
设置一个名称为blog,值为css9.net的cookie:
$.cookie("blog", "css9.net");
设置一个名称为blog,值为css9.net的cookie,同时设置过期时间(expires属性)为7天:
$.cookie("blog", "css9.net", { expires: 7 });
设置一个名称为blog,值为css9.net的cookie,设置过期时间(expires属性)为7天,同时设置cookie的path属性为”/admin”
$.cookie("blog", "css9.net", { path: '/admin', expires: 7 });
读取Cookie:
读取名称为blog的cookie值:
alert( $.cookie("blog") );
删除cookie:
$.cookie("example", null);

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 = $.extend({}, options); // clone object since it's unexpected behavior if the expired property were changed
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
}
// NOTE Needed to parenthesize options.path and options.domain
// in the following expressions, otherwise they evaluate to undefined
// in the packed version for some reason...
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;
}
};
