JS对数字进行货币格式化并且保留两位小数点，小数用0补全

/** * 将数值四舍五入(保留2位小数)后格式化成金额形式 * * @param num 数值(Number或者String) * @return 金额格式的字符串,如'1,234,567.45' * @type String */function formatCurrency(num) { num = num.toString().replace(/\$|\,/g,''); if(isNaN(num)) num = "0"; sign = (num == (num = Math.abs(num))); num = Math.floor(num*100+0.50000000001); cents = num0; 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);}/** * 将数值四舍五入(保留1位小数)后格式化成金额形式 * * @param num 数值(Number或者String) * @return 金额格式的字符串,如'1,234,567.4' * @type String */function formatCurrencyTenThou(num) { num = num.toString().replace(/\$|\,/g,''); if(isNaN(num)) num = "0"; sign = (num == (num = Math.abs(num))); num = Math.floor(num*10+0.50000000001); cents = num; num = Math.floor(num/10).toString(); 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);}
