$.cookie(&#39;the_cookie_expires_07&#39;, &#39;世界是座魔方大厦&#39;, {
expires: 7
});
//读取cookie
var value = $.cookie(&#39;the_cookie&#39;);
var value_07 = $.cookie(&#39;the_cookie_expires_07&#39;);
$(&#39;p&#39;).html(&#39;读取cookie的值：&#39; + value + &#39;<br />&#39; + &#39;读取cookie存在7天的值：&#39; + value_07);
});
