从tenpay找到的一段将金额小写转换成大写的js代码：

 1 var DX = function (num) {
 2   var strOutput = "";
 3   var strUnit = ‘仟佰拾亿仟佰拾万仟佰拾元角分‘;
 4   num += "00";
 5   var intPos = num.indexOf(‘.‘);
 6   if (intPos >= 0)
 7     num = num.substring(0, intPos) + num.substr(intPos + 1, 2);
 8   strUnit = strUnit.substr(strUnit.length - num.length);
 9   for (var i=0; i < num.length; i++)
10     strOutput += ‘零壹贰叁肆伍陆柒捌玖‘.substr(num.substr(i,1),1) + strUnit.substr(i,1);
11     return strOutput.replace(/零角零分$/, ‘整‘).replace(/零[仟佰拾]/g, ‘零‘).replace(/零{2,}/g, ‘零‘).replace(/零([亿|万])/g, ‘$1‘).replace(/零+元/, ‘元‘).replace(/亿零{0,3}万/, ‘亿‘).replace(/^元/, "零元");
12 };
