ie和safari中日期对象的javascript日期对象、getdate()、getmonth()和getfullyear

如果safari的日期对象的生成方式与chrome相同,那么至少在我的旧版本safari中,代码运行成功,如下所示:

function formatDateTimeToString(date) {
var dd = (date.getDate() < 10 ? '0' : '') + date.getDate();
var MM = ((date.getMonth() + 1) < 10 ? '0' : '') + (date.getMonth() + 1);
var yyyy = date.getFullYear();
var hours = (date.getHours() < 10 ? '0' : '') + date.getHours();
var minutes = (date.getMinutes() < 10 ? '0' : '') + date.getMinutes();
               return (dd + "." + MM + "." + yyyy + ' ' + hours + ':' + minutes);
            }

var d = document;
d.w = d.writeln;
var date = new Date("Mon Mar 25 2019 00:00:00 GMT+0100 (CET)");

/* this works */
d.w( formatDateTimeToString(date)+"<BR>"); 

// output:
// 24.03.2019 16:00

如果尝试使用包含连字符的字符串实例化日期对象,则在safari中可能会得到nan,如下所示:

var d = document;
d.w = d.writeln;

date = new Date("2019-03-24");
/* returns NaN */
d.w( formatDateTimeToString(date)+"<BR>");

date = new Date("03-24-2019");
/* this fails with NaN*/
d.w( formatDateTimeToString(date)+"<BR>");
