js判断日期是否已经过期

一、js判断日期是否已经过期 传参格式 2018-5-20 过期返回false 没有返回true

  function(date){
        var normalizeDate = date.split("-");
        var Month = new Date().getMonth() + 1;
        var year = new Date().getFullYear();

        if (normalizeDate[0] < year) {

            return false
        } else if(normalizeDate[0] == year){
            if (normalizeDate[1] < Month) {
                console.log(normalizeDate[1]< Month)
                return false;
            }else if(normalizeDate[1] == Month){
                if (normalizeDate[2] < this.day) {
                    return false;
                }else {
                    return true;
                };
            }else {
                return true;
            };
        } else{
            return true;
        };

    }

二、判断年月是否过期

  function(date){
        var normalizeDate = date.split("-");
        var Month = new Date().getMonth() + 3;
        var year = new Date().getFullYear();

        if (normalizeDate[0] < year) {

            return false
        } else if(normalizeDate[0] == year){
            if (normalizeDate[1] < Month) {
                console.log(normalizeDate[1]< Month)
                return false;
            }else if(normalizeDate[1] == Month){
                return true;
            }else {
                return true;
            };
        } else{
            return true;
        };

    }
