转自:https://blog.csdn.net/u010964869/article/details/51095827

显示格式为：yyyy-mm-dd hh:mi:ss

function formattime(val){

    if(val == "" || val == null || val == undefined){
        return "";
    }
    var date =  new Date(val);
    var year = parseInt(date.getFullYear());
    var month = (parseInt(date.getMonth())+1);
    var day = parseInt(date.getDate());
    day = day > 9 ? day:('0'+day);
    var hours = parseInt(date.getHours());
    hours = hours > 9 ? hours:('0'+hours);
    var minutes = parseInt(date.getMinutes());
    minutes = minutes > 9 ? minutes:('0'+minutes);
    var seconds = parseInt(date.getSeconds());
    seconds = seconds > 9 ? seconds:('0'+seconds);
    var time = year+'-'+month+'-'+day+' '+hours+':'+minutes+':'+seconds;

    return time;
}

 注:parseInt可以不要
