jquery操作session的方法

/此方法在java中不能使用


// jquery.session.js 简单使用方法添加数据
    $.session.set('key', 'value')
删除数据
    $.session.remove('key');获取数据
    $.session.get('key');
清除数据
    $.session.clear();

以下为jquery文件代码：新建复制即可使用
/*
* *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();
