The date is being returned as milliseconds since epoch. The code below creates a JS date object:

日期以自纪元以​​来的毫秒数返回。下面的代码创建了一个 JS 日期对象：

var d = new Date(1245398693390);
var formattedDate = d.getDate() + "-" + (d.getMonth() + 1) + "-" + d.getFullYear();
var hours = (d.getHours() < 10) ? "0" + d.getHours() : d.getHours();
var minutes = (d.getMinutes() < 10) ? "0" + d.getMinutes() : d.getMinutes();
var formattedTime = hours + ":" + minutes;

formattedDate = formattedDate + " " + formattedTime;

Here's a working fiddle.

这是一个工作小提琴。

Extend Date's prototype to include a format function like so (or find or create your own):

ExtendDate的原型以包含像这样的格式函数（或查找或创建您自己的）：

Date.prototype.format = function (formatString) {
    // Returns a formatted date string
    var month = this.getMonth() + 1,
        day = this.getDate(),
        year = this.getFullYear(),
        hours24 = this.getHours(),
        hours = (hours24 === 0 ? 12 : hours24 > 12 ? hours24 - 12 : hours24),
        meridiem = hours24 >= 12 ? "PM" : "AM",
        minutes = this.getMinutes(),
        seconds = this.getSeconds();

    return formatString.replace(/(MM)/g, month.padLeft(2, '0'))
        .replace(/(M)/g, month)
        .replace(/(dd)/g, day.padLeft(2, '0'))
        .replace(/(d)/g, day)
        .replace(/(yyyy)/ig, year)
        .replace(/(yy)/ig, year.toString().substring(2, 4))
        .replace(/(hh)/g, hours.padLeft(2, '0'))
        .replace(/(h)/g, hours)
        .replace(/(HH)/g, hours24.padLeft(2, '0'))
        .replace(/(H)/g, hours24)
        .replace(/(mm)/g, minutes.padLeft(2, '0'))
        .replace(/(m)/g, minutes)
        .replace(/(ss)/g, seconds.padLeft(2, '0'))
        .replace(/(s)/g, seconds)
        .replace(/(tt)/g, meridiem.toLowerCase())
        .replace(/(TT)/g, meridiem);
};

Then, to convert the timestamp into the desired format, dd-mm-yyyy hr:mn(as mentioned in your comment), you'd do the following:

然后，要将时间戳转换为所需的格式dd-mm-yyyy hr:mn（如您的评论中所述），您需要执行以下操作：

var dateString = new Date(timestamp).format("dd-MM-yyyy hh:mm");

[Edit]Here's the accompanying pad function:

[编辑]这是随附的打击垫功能：

Number.prototype.padLeft = function (width, padChar) {
    // Returns a padded string
    padChar = padChar || ' ';
    var value = this.toString();
    while (value.length < width) {
        value = padChar + value;
    }
    return value;
};

<script>
var timestamp=1326439320;
var date=new Date(timestamp);
var hours = date.getHours(); // minutes part from the timestamp
var minutes = date.getMinutes(); // seconds part from the timestamp
var seconds = date.getSeconds(); // will display time in 10:30:23 format
 var formattedTime = hours + ':' + minutes + ':' + seconds;
alert(formattedTime);
</script>
