微信小程序在wxs进行对new Date（）时间转换

Question

代码复制大佬的，但是一开始就报错TypeError: value.replace is not a function，不清楚怎么改

var readdate = function (value) {
    value = value.replace(".000+0000", "Z");
    var time = getDate(value);
    var hour = time.getHours();
    var minute = time.getMinutes();
    var second = time.getSeconds();
    hour = hour < 10 ? "0" + hour : hour;
    minute = minute < 10 ? "0" + minute : minute;
    second = second < 10 ? "0" + second : second;
    return hour + ":" + minute + ":" + second;
}

Answer 1

value传进来是个字符串，你传的是啥类型的，Date类型？
