//var Mum = number;
var Num = number.toString();//变量名称错了并且要转为string
    function parseChinese(n) {
        var c = ["零", "壹", "贰", "叁", "肆", "伍", "陆", "柒", "捌", "玖"];
        var p = ["分","角","元","拾","百","千","万","拾","百","千","亿","拾","百","千"];
        var temp = (/^(0|[1-9])\d*(\.\d+)?$/).test(n)? n : null;
        var i = -1,result = null;
        if(temp) {
            temp = parseFloat(temp).toFixed(2);
            i = (/\.\d+$/).test(temp)? -1 : 1;
            result = temp.toString().replace(/\./g, "").split("").reverse().join("").replace(/\d/g, function(a) {i++; return p[i] + c[a]}).split("").reverse().join("").replace(/零(千|百|拾|角)/g, "零").replace(/(零)+/g, "零").replace(/(千|百|拾)零(元|万|亿)/g,"$1$2").replace(/(亿零)万/g, "$1").replace(/(万零)元/g, "$1").replace(/(零)+/g, "零").replace(/(亿)零(元)/g, "$1$2").replace(/(零角)*零分$/g, "整");

你只是 return了，并没有显示出来啊等于你考试在草纸上算了半天没写到考卷上一样。。

哈，没仔细看代码。。0的时候有document.write了。。仔细看了下代码。首先第11行，Mum应该是笔误，应该是Num其次Num是数字不是字符串,没有replace方法，要转换一下，Num = number+''，或者像楼上的number.toString()
写一个比较狂野的。(function(){
var money = window.money = function (m) {
this._orgMoney = m;

m = m.toString();
