JSON数据如何转换为时间格式？

function jsonDateFormat(jsonDate) {//json日期格式转换为正常格式
try {
var date = new Date(parseInt(jsonDate.replace("/Date(", "").replace(")/", ""), 10));
var month = date.getMonth() + 1 < 10 ? "0" + (date.getMonth() + 1) : date.getMonth() + 1;
var day = date.getDate() < 10 ? "0" + date.getDate() : date.getDate();
var hours = date.getHours();
var minutes = date.getMinutes();
var seconds = date.getSeconds();
var milliseconds = date.getMilliseconds();
return date.getFullYear() + "-" + month + "-" + day + " " + hours + ":" + minutes + ":" + seconds + "." + milliseconds;
} catch (ex) {
return "";
}
}
