tips：
js读取php的中文cookie需要 "decodeURIComponent (escape( )) "函数处理
php读取js的中文cookie需要 "unescape( )" 函数处理
----------------------------------------------
如果只是要在js中使用，可以用下面的方法：
1，localStorage.setItem("cookie", 123);//保存cookie
2，localStorage.getItem("cookie");//获取cookie值
3，localStorage.removeItem("cookie");//清除cookie值
