代码如下:

var getTime= function(second_time){
  var time = parseInt(second_time) + "秒";
  if( parseInt(second_time )> 60){
    var second = parseInt(second_time) % 60;
    var min = parseInt(second_time/60);
    time = min + "分" + second + "秒";
    if( min > 60 ){
      min = parseInt(second_time / 60) % 60;
      var hour = parseInt( parseInt(second_time / 60) /60 );
      time = hour + "小时" + min + "分" + second + "秒";
      if( hour > 24 ){
        hour = parseInt( parseInt(second_time / 60) /60 ) % 24;
        var day = parseInt( parseInt( parseInt(second_time / 60) /60 ) / 24 );
        time = day + "天" + hour + "小时" + min + "分" + second + "秒";
      }
    }
  }
  return time;
}
