jqgrid colModel 中formatter的用法

var historys = function()
{
 function format(cellvalue){ //cellvalue表示当前单元格的值
  var str = "";
        var hour = 0;
        var minute = 0;
        var second = 0;

        second = cellvalue / 1000;

        if (second > 60) {
            minute = second / 60;
            second = second % 60;
        }
        if (minute > 60) {
            hour = minute / 60;
            minute = minute % 60;
        }
       
        var strHour = parseInt(hour);
        var strMinute = parseInt(minute); 
        var strSecond = parseInt(second);
       
        return (strHour + "小时" + strMinute + "分钟"
                + strSecond + "秒");
 }
