JS控制阿拉伯数字转为中文大写示例代码_javascript技巧

复制代码 代码如下:

function NoToChinese(num) {
if (!/^\d*(\.\d*)?$/.test(num)) { alert("Number is wrong!"); return "Number is wrong!"; }
var AA = new Array("零", "壹", "贰", "叁", "肆", "伍", "陆", "柒", "捌", "玖");
var BB = new Array("", "拾", "佰", "仟", "萬", "億", "点", "");
var a = ("" + num).replace(/(^0*)/g, "").split("."), k = 0, re = "";
for (var i = a[0].length - 1; i >= 0; i--) {
switch (k) {
case 0: re = BB[7] + re; break;
case 4: if (!new RegExp("0{4}\\d{" + (a[0].length - i - 1) + "}$").test(a[0]))
re = BB[4] + re; break;
case 8: re = BB[5] + re; BB[7] = BB[5]; k = 0; break;
}
if (k % 4 == 2 && a[0].charAt(i + 2) != 0 && a[0].charAt(i + 1) == 0) re = AA[0] + re;
if (a[0].charAt(i) != 0) re = AA[a[0].charAt(i)] + BB[k % 4] + re; k++;
}

if (a.length > 1) //加上小数部分(如果有小数部分)
{
re += BB[6];
for (var i = 0; i }
return re;
}
