在jquery中能用session吗

$.session.set('key', 'value')

$.session.remove('key');

$.session.get('key');

$.session.clear();

/** *说明：不可以获取java的session* 语法：添加数据$.session.set('key', 'value')

删除数据$.session.remove('key');

获取数据$.session.get('key');

清除数据$.session.clear();*/

(function($){

$.session = {

_id: null,

_cookieCache: undefined,

_init: function(){if (!window.name) {window.name = Math.random();}this._id = window.name;this._initCache();

// See if we've changed protcols

var matches = (new RegExp(this._generatePrefix() + "=([^;]+);")).exec(document.cookie);if (matches && document.location.protocol !== matches[1]) {this._clearSession();for (var key in this._cookieCache) {try {window.sessionStorage.setItem(key, this._cookieCache[key]);} catch (e) {};}}

document.cookie = this._generatePrefix() + "=" + document.location.protocol + ';path=/;expires=' + (new Date((new Date).getTime() + 120000)).toUTCString();
