复制代码 代码如下:

function cal_pace(d,h,m,s){

var distance = d;

var hours = h;

var minutes = m;

var seconds = s;

if(distance.length > 0 && hours.length > 0 && minutes.length > 0 && seconds.length > 0)

{

var speed = parseFloat(hours) * 60.0 + parseFloat(minutes) + parseFloat(seconds) / 60.0;

speed = speed / parseFloat(distance);

var speed_minutes = Math.floor(speed);

var speed_seconds = Math.floor((speed - speed_minutes) * 60.0);

return (speed_minutes + ''' + speed_seconds + '"').toString();

}

return '0'0"';

}
