js计算百分比
function GetPercent(num, total) { /// <summary> /// 求百分比 /// </summary> /// <param name="num">当前数</param> /// <param name="total">总数</param> num = parseFloat(num); total = parseFloat(total); if (isNaN(num) || isNaN(total)) { return "-"; } return total <= 0 ? "0%" : (Math.round(num / total * 10000) / 100.00)+"%"; }
使用方法如下:
GetPercent(1,100);
结果:
1%;
