// Validate input string:

// Trim zeros at the beginning.
// Assert the number is not greater than the maximum number.
if (Number(currencyDigits) > MAXIMUM_NUMBER) {
$("#upperRMB").val("数字过大");
return "";
}
// Process the coversion from currency digits to characters:
// Separate integral and decimal parts before processing coversion:
parts = currencyDigits.split(".");
if (parts.length > 1) {
integral = parts[0];
decimal = parts[1];
// Cut down redundant decimal digits that are after the second.
decimal = decimal.substr(0, 2);
} else {
integral = parts[0];
decimal = "";
}
// Prepare the characters corresponding to the digits:
digits = new Array(CN_ZERO, CN_ONE, CN_TWO, CN_THREE, CN_FOUR, CN_FIVE, CN_SIX, CN_SEVEN, CN_EIGHT, CN_NINE);
radices = new Array("", CN_TEN, CN_HUNDRED, CN_THOUSAND);
bigRadices = new Array("", CN_TEN_THOUSAND, CN_HUNDRED_MILLION);
decimals = new Array(CN_TEN_CENT, CN_CENT);
// Start processing:
outputCharacters = "";
// Process integral part if it is larger than 0:
if (Number(integral) > 0) {
zeroCount = 0;
for (i = 0;
i < integral.length;
i++) {
p = integral.length - i - 1;
d = integral.substr(i, 1);
quotient = p / 4;
modulus = p % 4;
if (d == "0") {
zeroCount++;
} else {
if (zeroCount > 0) {
outputCharacters += digits[0];
} zeroCount = 0;
outputCharacters += digits[Number(d)] + radices[modulus];
} if (modulus == 0 && zeroCount < 4) {
outputCharacters += bigRadices[quotient];
}
} outputCharacters += CN_DOLLAR;
}
// Process decimal part if there is:
if (decimal != "") {
realNotEmpty = false;
for (i = 0;
i < decimal.length;
i++) {
d = decimal.substr(i, 1);
if (d != "0") {
outputCharacters += digits[Number(d)] + decimals[i];
realNotEmpty = true;
}
} if (!realNotEmpty) {
decimal = "";
}
}
// Confirm and return the final output string:
if (outputCharacters == "") {
outputCharacters = CN_ZERO + CN_DOLLAR;
} if (decimal == "") {
outputCharacters += CN_INTEGER;
}

最后 outputCharacters 就是转换后的结果了。
