JS 格林威治时间格式（GMT)格式化

Posted 2020-09-28 天使不哭

Date.prototype.format = function (format) {
var o = {
"M+": this.getMonth() + 1, //month
"d+": this.getDate(), //day
"h+": this.getHours(), //hour
"m+": this.getMinutes(), //minute
"s+": this.getSeconds(), //second
"q+": Math.floor((this.getMonth() + 3) / 3), //quarter
"S": this.getMilliseconds() //millisecond
}
if (/(y+)/.test(format)) format = format.replace(RegExp.$1,
(this.getFullYear() + "").substr(4 - RegExp.$1.length));
for (var k in o) if (new RegExp("(" + k + ")").test(format))
format = format.replace(RegExp.$1,
RegExp.$1.length == 1 ? o[k] :
("00" + o[k]).substr(("" + o[k]).length));
return format;
}

function DateTimeFormatter(value) {
if (value == undefined) {
return "";
}
/*json格式时间转js时间格式*/
value = value.substr(1, value.length - 2);
var obj = eval(‘(‘ + "{Date: new " + value + "}" + ‘)‘);
var dateValue = obj["Date"];
if (dateValue.getFullYear() < 1900) {
return "";
}
//return dateValue
return dateValue.format("yyyy-MM-dd hh:mm:ss");
}
