日期与时间戳相互转化（js）

function datetime_to_unix(datetime){

    var tmp_datetime = datetime.replace(/:/g,'-');

    tmp_datetime = tmp_datetime.replace(/ /g,'-');

    var arr = tmp_datetime.split("-");

    var now = new Date(Date.UTC(arr[0],arr[1]-1,arr[2],arr[3]-8,arr[4],arr[5]));

    return parseInt(now.getTime()/1000);

}

 

function unix_to_datetime(unix) {

    var now = new Date(parseInt(unix) * 1000);

    return now.toLocaleString().replace(/年|月/g, "-").replace(/日/g, " ");

}

 

var datetime = '2012-11-16 10:36:50';

var unix = datetime_to_unix(datetime);

document.write(datetime+' 转换后的时间戳为: '+unix+'

');

 

var unix = 1353033300;

var datetime = unix_to_datetime(unix);

document.write(unix+' 转换后的日期为: '+datetime);
