Jquery 操作Cookie方法 jquery Cookie插件

Jquery 操作Cookie方法  jquery Cookie插件,需要在js文件里面加上下面扩展插件代码然后才能使用。

$.extend({
/**
1. 设置cookie的值,把name变量的值设为value
example $.cookie(“name”, “value”);
2.新建一个cookie 包括有效期 路径 域名等
example $.cookie(“name”, “value”, {expires: 7, path: “/”, domain: “jquery.com”, secure: true});
3.新建cookie
example $.cookie(“name”, “value”);
4.删除一个cookie
example $.cookie(“name”, null);
5.取一个cookie(name)值给myvar
var account= $.cookie(“name”);
**/
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;
}
}

});

============================

关于cookie的path设置需要注意,如果不设置path:’/’的话,path则会根据目录自动设置[如:http://www.xxx.com/user/,path会被设置为 '/user']
