How to get file's last modified date with script?

File object has a specific property modified, that you want to look at.

var myFile = File('pathToFile.js');
alert(myFile.modified);

great！ it works!   but can it transform to other format, like 201901160102  ?

Sure

alert(myFile.modified.getTime());

Actually, I just re-read your second reply, where you want to format time. Here's one approach to that. Feel free to juggle around to format it your way. Also read more about Date() format here Date | MDN

var myFile = File('pathToFile.js');
var modified = myFile.modified;
var formatedTime = formatDate(modified);
alert(formatedTime);
function formatDate(date) {
    var year = date.getFullYear();
    var month = date.getMonth() + 1; // In JS world month starts at 0, not 1;
    var day = date.getDate();
    var hours = date.getHours();
    var minutes = date.getMinutes();
    var seconds = date.getSeconds();
    var result = year + pad(month) + pad(day) + pad(hours) + pad(minutes) + pad(seconds);
    return result;
}
function pad(value, padding) {
    padding = padding || 2;
    var string = value.toString();
    while (string.length < 2) {
        string = '0' + string;
    }
    return string;
}
