小程序问题 关于时间转化问题

先上圖

大佬们看一下 我图片上方是开发工具显示 但是到了手机端 却变成刚刚 我也查了一下 值没有传进去显示null, 这我就不懂了 我全程打印 都是对的 就是手机一预览就接不到值
麻烦大神帮我看看 下面是我的代碼

因为不同的操作系统或浏览器中，Date对象能够解析的日期字符串的格式有所不同。

你看看rstringTime = res.data.list[i].createDate获取的日期字符串是什么格式。
可能这种格式在你的手机浏览器中不支持。需要手动解析成年，月，日，时，分，秒等值传给new Date()
如2018年8月2日15时30分54秒,就要解析为new Date(2018,7,2,15,30,54);（注意月份要比实际的值减1）

例如：获取的日期字符串格式2018-08-02T15:05:50 可以这样解析

    for (var i = 0; i < res.data.list.length; i++) {
      var rstringTime = res.data.list[i].createDate;
      var arr = rstringTime.match(/\d+/g);
      var rtimestamp2 = new Date(arr[0]-0,arr[1]-1,arr[2]-0,arr[3]-0,arr[4]-0,arr[5]-0).getTime();
      rcreateDate.push(rtimestamp2)
    }

var rstringTime = res.data.list[i].createDate;获取的是日期的字符串值，并用 new Date(rstringTime).getTime();解析日期的字符串。
但是在不同的操作系统或浏览器中，Date对象能够解析的日期字符串的格式存在许多差异，因此最好还是手动解析日期字符串（在需要适应不同格式时库能起到很大帮助）。

如：你的 rstringTime 获取的日期字符串格式是"2018-08-02T15:05:50"

                var rcreateDate = []
                for (var i = 0; i < res.data.list.length; i++) {
                    var rstringTime = res.data.list[i].createDate;
                    var arr = rstringTime.match(/\d+/g);
                    var rtimestamp2 = new Date(arr[0]-0,arr[1]-1,arr[2]-0,arr[3]-0,arr[4]-0,arr[5]-0).getTime();
                    rcreateDate.push(rtimestamp2)
                }

//获取当前时间戳
var timestamp = Date.parse(new Date());
timestamp = timestamp / 1000;
console.log("当前时间戳为：" + timestamp);

//获取当前时间
var n = timestamp * 1000;
var date = new Date(n);
//年
var Y = date.getFullYear();
//月
var M = (date.getMonth() + 1 < 10 ? '0' + (date.getMonth() + 1) : date.getMonth() + 1);
//日
var D = date.getDate() < 10 ? '0' + date.getDate() : date.getDate();
//时
var h = date.getHours();
//分
var m = date.getMinutes();
//秒
var s = date.getSeconds();

console.log("当前时间：" +Y+M+D+h+":"+m+":"+s);

//转换为时间格式字符串
console.log(date.toDateString());

console.log(date.toGMTString());

console.log(date.toISOString());

console.log(date.toJSON());

console.log(date.toLocaleDateString());

console.log(date.toLocaleString());

console.log(date.toLocaleTimeString());

console.log(date.toString());

console.log(date.toTimeString());

console.log(date.toUTCString());

2018-08-02T15:05:50 这个就是标准的时间格式 https://devdocs.io/javascript/global_objects/date 自然直接使用set方法来设置也是可以的
或者 new Date(year, monthIndex [, day [, hours [, minutes [, seconds [, milliseconds]]]]]);
例如:
new Date(2013, 2, 1, 1, 10) // 2013-03-01T01:10:00.
