var date = eval(data.Data.Entity.Slrq.replace(/\/Date\((\d )\)\//gi, "new Date($1)"));  
alert(date.format("yyyy-MM-dd HH:mm:ss"));  
alert(dateFormat(date, "yyyy-MM-dd HH:mm:ss"));  

如果你在获取时间信息上有困难，你可以尝试这样做:

    d.date = d.date.replace('/Date(', '');
    d.date = d.date.replace(')/', '');  
    var expDate = new Date(parseInt(d.date));

使用string解析日期字符串。替换为反向参考:

var milli = "/Date(1245398693390)/".replace(/\/Date\((-?\d+)\)\//, '$1');
var d = new Date(parseInt(milli));

前面的答案都表明你可以做以下事情:

var d = eval(net_datetime.slice(1, -1));

然而，这在Chrome或FF中都不起作用，因为得到的评估字面上是:

// returns the current timestamp instead of the specified epoch timestamp
var d = Date([epoch timestamp]);

正确的做法是:

var d = eval("new " + net_datetime.slice(1, -1)); // which parses to

var d = new Date([epoch timestamp]); 

我认为，从1970,1,1的转换需要双舍入到小数点后0位

DateTime d1 = new DateTime(1970, 1, 1);
DateTime d2 = dt.ToUniversalTime();
TimeSpan ts = new TimeSpan(d2.Ticks - d1.Ticks);
return Math.Round( ts.TotalMilliseconds,0);

在客户端我使用

new Date(+data.replace(/\D/g, ''));
