//格式化金钱(  9,999.00)
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 = 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);
}

 

在html页面里面格式化金额

例如在span标签里

<span> <script>var money =formatCurrency(999999.0); document.write(money)</script> </span>

输出内容 999,999.00

 

格式化日期

//格式化日期 fmt是格式化格式

        "H+": this.getHours(), //小时         
        "m+": this.getMinutes(), //分         
        "s+": this.getSeconds(), //秒         
        "q+": Math.floor((this.getMonth() + 3) / 3), //季度         
        "S": this.getMilliseconds() //毫秒         
    };
    var week = {
        "0": "/u65e5",

        "5": "/u4e94",
        "6": "/u516d"
    };
    if (/(y+)/.test(fmt)) {
        fmt = fmt.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length));
    }
    if (/(E+)/.test(fmt)) {
        fmt = fmt.replace(RegExp.$1, ((RegExp.$1.length > 1) ? (RegExp.$1.length > 2 ? "/u661f/u671f" : "/u5468") : "") + week[this.getDay() + ""]);
    }
    for (var k in o) {
        if (new RegExp("(" + k + ")").test(fmt)) {
            fmt = fmt.replace(RegExp.$1, (RegExp.$1.length == 1) ? (o[k]) : (("00" + o[k]).substr(("" + o[k]).length)));
        }
    }
    return fmt;

// 对Date的扩展,将 Date 转化为指定格式的String
// 月(M)、日(d)、小时(h)、分(m)、秒(s)、季度(q) 可以用 1-2 个占位符, 
// 年(y)可以用 1-4 个占位符,毫秒(S)只能用 1 个占位符(是 1-3 位的数字) 
// 例子: 
// (new Date()).Format("yyyy-MM-dd hh:mm:ss.S") ==> 2006-07-02 08:09:04.423
