将数字转换成大写的人民币,方法有很多,本例介绍的是使用js来完成的,看看下面的实现代码
function
changeNumMoneyToChinese(money) {
var
cnNums =
new
Array(
"零"
,
"壹"
,
"贰"
,
"叁"
,
"肆"
,
"伍"
,
"陆"
,
"柒"
,
"捌"
,
"玖"
);
//汉字的数字
var
cnIntRadice =
new
Array(
""
,
"拾"
,
"佰"
,
"仟"
);
//基本单位
var
cnIntUnits =
new
Array(
""
,
"万"
,
"亿"
,
"兆"
);
//对应整数部分扩展单位
var
cnDecUnits =
new
Array(
"角"
,
"分"
,
"毫"
,
"厘"
);
//对应小数部分单位
var
cnInteger =
"整"
;
//整数金额时后面跟的字符
var
cnIntLast =
"元"
;
//整型完以后的单位
var
maxNum = 999999999999999.9999;
//最大处理的数字
var
IntegerNum;
//金额整数部分
var
DecimalNum;
//金额小数部分
var
ChineseStr =
""
;
//输出的中文金额字符串
var
parts;
//分离金额后用的数组,预定义
if
(money ==
""
) {
return
""
;
}
money = parseFloat(money);
if
(money >= maxNum) {
alert(
'超出最大处理数字'
);
return
""
;
}
if
(money == 0) {
ChineseStr = cnNums[0] + cnIntLast + cnInteger;
return
ChineseStr;
}
money = money.toString();
//转换为字符串
if
(money.indexOf(
"."
) == -1) {
IntegerNum = money;
DecimalNum =
''
;
}
else
{
parts = money.split(
"."
);
IntegerNum = parts[0];
DecimalNum = parts[1].substr(0, 4);
}
if
(parseInt(IntegerNum, 10) > 0) {
//获取整型部分转换
var
zeroCount = 0;
var
IntLen = IntegerNum.length;
for
(
var
i = 0; i < IntLen; i++) {
var
n = IntegerNum.substr(i, 1);
var
p = IntLen - i - 1;
var
q = p / 4;
var
m = p % 4;
if
(n ==
"0"
) {
zeroCount++;
}
else
{
if
(zeroCount > 0) {
ChineseStr += cnNums[0];
}
zeroCount = 0;
//归零
ChineseStr += cnNums[parseInt(n)] + cnIntRadice[m];
}
if
(m == 0 && zeroCount < 4) {
ChineseStr += cnIntUnits[q];
}
}
ChineseStr += cnIntLast;
//整型部分处理完毕
}
if
(DecimalNum !=
''
) {
//小数部分
var
decLen = DecimalNum.length;
for
(
var
i = 0; i < decLen; i++) {
var
n = DecimalNum.substr(i, 1);
if
(n !=
'0'
) {
ChineseStr += cnNums[Number(n)] + cnDecUnits[i];
}
}
}
if
(ChineseStr ==
''
) {
ChineseStr += cnNums[0] + cnIntLast + cnInteger;
}
else
if
(DecimalNum ==
''
) {
ChineseStr += cnInteger;
}
return
ChineseStr;
}
