ios 中倒计时计算,时间戳为NaN

// 倒计时
daojishi(params) {
let _this = this;
let datetemp = this.servertimes;
let lasttime = Date.parse(datetemp.replace(/-/g,"/"));
// new Date(datetemp).getTime() 为NaN
let nowtime = parseInt(new Date().getTime());
let intDiff =parseInt(lasttime - nowtime); //当前时间 - 预设时间
if(intDiff>0){
intDiff = parseInt(intDiff/1000)
window.setInterval(function () {
var day = 0,hour = 0,minute = 0,second = 0; //默认值
if (intDiff > 0) {
day = Math.floor(intDiff / (60 * 60 * 24));
hour = Math.floor(intDiff / (60 * 60)) - (day * 24);
minute = Math.floor(intDiff / 60) - (day * 24 * 60) - (hour * 60);
second = Math.floor(intDiff) - (day * 24 * 60 * 60) - (hour * 60 * 60) - (minute * 60);
}
if (minute <= 9) minute = '0' + minute;
if (second <= 9) second = '0' + second;
_this.servertime = hour +':'+ minute +':'+ second +" 内上门服务"
intDiff--;
}, 1000);
}else{
_this.servertime = "逾期请联系客服";
}
},

安卓正常 Number.isNaN(new Date("2011/11/11 20:10:10").getTime())    //false

ios中使用 Number.isNaN(new Date("2011/11/11 20:10:10").getTime())    //true

      Number.isNaN(Date.parse("2011-11-11 20:10:10".replace(/-/g,"/"))) //false

综上:在ios中使用时间戳加减使用 Data.parse()转换
