vue全局函数存储cookie读取cookie

//设置cookie,放在main.js

Vue.prototype.setCookie = function(c_name,value,expiredays) {
  var exdate=new Date()
  exdate.setDate(exdate.getDate()+expiredays)
  document.cookie=c_name+ "=" +escape(value)+
    ((expiredays==null) ? "" : ";expires="+exdate.toGMTString())
};


//获取cookie

Vue.prototype.getCookie=function(c_name) {
  if (document.cookie.length>0)
  {
    var  c_start=document.cookie.indexOf(c_name + "=")
    if (c_start!=-1)
    {
      c_start=c_start + c_name.length+1
     var c_end=document.cookie.indexOf(";",c_start)
      if (c_end==-1) c_end=document.cookie.length
      return unescape(document.cookie.substring(c_start,c_end))
    }
  }
  return ""
};

使用：

that.setCookie('setCookie',"存储cookie",365);
that.getCookie('setCookie');
