//jQuery操作cookie的插件,大概的使用方法如下:
/*
	(1)设置cookie的值  example $.cookie(’the_cookie’, ‘the_value’);
	(2)新建一个cookie 包括有效期 路径 域名等  
		example $.cookie(’the_cookie’, ‘the_value’, {expires: 7, path: ‘/’, domain: ‘jquery.com’, secure: true});  
	(3)新建cookie  example $.cookie(’the_cookie’, ‘the_value’); 
	(4)删除一个cookie  example $.cookie(’the_cookie’, null);
