JQuery读写COOKIE文件
页面调用只要引进这个文件
$.cookie("name"); //根据cookie名字取到cookie值
$.cookie("name", "value");//设置cookie 名字,值
$.cookie("name", value, { expires: 7 }); //设置cookie 名字,值,生命周期等属性
$.cookie("name", null); //根据cookie名移除cookie
*/
jQuery.cookie = function (name, value, options) {
if (typeof value != 'undefined') {
options = options || {};
if (value === null) {
value = '';
options = $.extend({}, options);
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('');

var cookies = document.cookie.split(';');
for (var i = 0; i < cookies.length; i++) {
var cookie = jQuery.trim(cookies);
if (cookie.substring(0, name.length + 1) == (name + '=')) {
