js实现完美兼容各大浏览器的人民币大小写相互转换_javascript技巧

/*小写转大写*/

var xcc= "12.22";
document.write(xcc+"=>"+formatRMB(xcc)+"
");

/*大写转小写*/

var rrrr = "壹拾贰元贰角贰分";
document.write(rrrr+"=>"+parseRMB(rrrr));

输出结果：
12.22=>壹拾贰元贰角贰分
壹拾贰元贰角贰分=>12.22

我们来看下具体实例

var c = "零壹贰叁肆伍陆柒捌玖".split("");
// ["零","壹","贰","叁","肆","伍","陆","柒","捌","玖"]
var _c = {}; // 反向对应关系
for ( var i = 0; i "+formatRMB(xcc)+"
");
 
/*大写转小写*/
var rrrr = "壹拾贰元贰角贰分";
document.write(rrrr+"=>"+parseRMB(rrrr));

再来看一个将RMB转化为大写的例子

  function numToCny(num){
  var capUnit = ['万','亿','万','圆',''];
  var capDigit = { 2:['角','分',''], 4:['仟','佰','拾','']};
  var capNum=['零','壹','贰','叁','肆','伍','陆','柒','捌','玖'];
  if (((num.toString()).indexOf('.') > 16)||(isNaN(num)))
  return '';
  num = (Math.round(num*100)/100).toString();
  num =((Math.pow(10,19-num.length)).toString()).substring(1)+num;
  var i,ret,j,nodeNum,k,subret,len,subChr,CurChr=[];
  for (i=0,ret='';i
