js时间带T格式转常规时间

2020-03-18T18:55:27.207转2020-03-18 18:55

安卓会把这个带T字母的时间看做UTC时间格式，（包括ios打包后也会相差8个小时）与北京时间相差8个小时。你要将UTC时间转化为北京时间然后进行格式化。GMT +0800 已经是加了8个小时的了。或者你直接把T替换掉，然后格式化，忘记是看的是哪位大哥的了

// 字符串转换成时间 ios中要把毫秒去掉
function toTime(strTime) {
 if (!strTime) {
    return '';
 }
 var myDate = new Date(strTime + '+0800');
 if (myDate == 'Invalid Date') {
  strTime = strTime.replace(/T/g, ' ');
  strTime = strTime.replace(/-/g, '/');
  strTime = strTime.replace(/\.\d+/, ' ');//去掉毫秒
  myDate = new Date(strTime + '+0800'); 
 } 
 return myDate; //输出的也是带T时间格式，但在安卓和ios上时间保持一致
}

最终的代码：

getParseTime:function(time, cFormat){   //('2020-03-18T18:55:27.207', '{y}-{m}-{d} | {h}:{i}' )

    if (!time) {
        return '';
    }
    var myDate = new Date(time + '+0800');
    if (myDate == 'Invalid Date') {
        time = time.replace(/T/g, ' ');
        time = time.replace(/-/g, '/');
        time = time.replace(/\.\d+/, ' ');//去掉毫秒
        myDate = new Date(time + '+0800');
    }
    time = myDate;


    if (time == null) {
        return '';
    }
    if (arguments.length === 0) {
        return null
    }
    var format = cFormat || '{y}-{m}-{d} {h}:{i}:{s}'
    var date
    if (typeof time === 'object') {
        date = time
    } else {
        if ((typeof time === 'string') && (/^[0-9]+$/.test(time))) {
            time = parseInt(time)
        }
        if ((typeof time === 'number') && (time.toString().length === 10)) {
            time = time * 1000
        }
        date = new Date(time)
    }
    var formatObj = {
        y: date.getFullYear(),
        m: date.getMonth() + 1,
        d: date.getDate(),
        h: date.getHours(),
        i: date.getMinutes(),
        s: date.getSeconds(),
        a: date.getDay()
    }
    var time_str = format.replace(/{([ymdhisa])+}/g, (result, key) => {
        var value = formatObj[key]
        // Note: getDay() returns 0 on Sunday
        if (key === 'a') {
            return ['日', '一', '二', '三', '四', '五', '六'][value]
        }
        //return value.toString().padStart(2, '0')  //时间补零，padStart可能出现兼容问题
        return value.toString()
    })
    return time_str
},

如果时间相差8个小时的就用以下代码：

getParseTime:function(time){ 

                var date = time//"2019-11-23T00:00:00.000+0000";
                var arr=date.split("T");
                var d=arr[0];
                var darr = d.split('-');

                var t=arr[1];
                var tarr = t.split('.000');
                var marr = tarr[0].split(':');

                var dd = parseInt(darr[0])+"/"+parseInt(darr[1])+"/"+parseInt(darr[2])+" "+parseInt(marr[0])+":"+parseInt(marr[1])+":"+parseInt(marr[2]);

                function formatDateTime (date) {
                    let time = new Date(Date.parse(date));
                    time.setTime(time.setHours(time.getHours() + 8));

                    // alert(time);
                    // if (!isNaN(time)) {
                    //     return new Date(Date.parse(date.replace(/-/g, "/")));
                    // } else {
                    let Y = time.getFullYear() + '-';
                    let M = addZero(time.getMonth() + 1) + '-';
                    let D = addZero(time.getDate()) + ' ';
                    let h = addZero(time.getHours()) + ':';
                    let m = addZero(time.getMinutes()) + ':';
                    let s = addZero(time.getSeconds());
                    return Y + M + D + h + m + s;
                    // }
                };
                // 数字补0操作
                function addZero(num) {
                    return num < 10 ? '0' + num : num;
                };


                return formatDateTime(dd)

                // const date = new Date("2019-11-23T00:00:00.000+0000");
                // console.log("date:",date);
                console.log("Date:",new Date());

},
