【工作笔记】js常用方法--格式化时间、格式化金额

// 格式化时间function formatTime (time){var format = "yyyy-MM-dd HH:mm:ss";var t = new Date(time);var tf = function(i){return (i < 10 ? '0' : '') + i};return format.replace(/yyyy|MM|dd|HH|mm|ss/g, function(a){switch(a){case 'yyyy':return tf(t.getFullYear());break;case 'MM':return tf(t.getMonth() + 1);break;case 'mm':return tf(t.getMinutes());break;case 'dd':return tf(t.getDate());break;case 'HH':return tf(t.getHours());break;case 'ss':return tf(t.getSeconds());break;}})}

/** * 金额格式化 */function formatCurrencyFen(num) {num = num / 100;num = num.toString().replace(/\$|\,/g, '');if (isNaN(num))num = "0";sign = (num == (num = Math.abs(num)));num = Math.floor(num * 100 + 0.50000000001);cents = num % 100;num = Math.floor(num / 100).toString();if (cents < 10)cents = "0" + cents;for (var i = 0; i < Math.floor((num.length - (1 + i)) / 3); i++)num = num.substring(0, num.length - (4 * i + 3)) + ','+ num.substring(num.length - (4 * i + 3));return (((sign) ? '' : '-') + num + '.' + cents);}
