javascript将毫秒转换成hh:mm:ss的形式

function formatMilliseconds(value) { 
	var second = parseInt(value) / 1000;       // second
	var minute = 0;                            // minute
	var hour = 0;                              // hour
	if(second > 60) { 
		minute = parseInt(second / 60); 
		second = parseInt(second % 60); 
		if(minute > 60) { 
			hour = parseInt(minute / 60); 
			minute = parseInt(minute % 60); 
		} 
	} 
	var result;
	if(second >= 10) {
		result = "" + parseInt(second); 
	}else{
		result = "" + "0" + parseInt(second); 
	}
	if(minute >= 10) { 
		result = "" + parseInt(minute) + ":" + result;
	}
	else{
		result = "" + "0" + parseInt(minute) + ":" + result;
	}
	if(hour >= 10) { 
		result = "" + parseInt(hour) + ":" + result; 
	}
	else{
		result = "" + "0" + parseInt(hour) + ":" + result;
	}
	return result;
