用JavaScript将数字转换为大写金额

var digitUppercase = function(n) {

  var fraction = ['角', '分'];

  var digit = [

    '零', '壹', '贰', '叁', '肆',

    '伍', '陆', '柒', '捌', '玖'

  ];

  var unit = [

    ['元', '万', '亿'],

    ['', '拾', '佰', '仟']

  ];

  var head = n < 0 ? '欠' : '';

  n = Math.abs(n);

  var s = '';

  for (var i = 0; i < fraction.length; i++) {

    s += (digit[Math.floor(n * 10 * Math.pow(10, i)) % 10] + fraction[i]).replace(/零./, '');

  }

  s = s || '整';

  n = Math.floor(n);

  for (var i = 0; i < unit[0].length && n > 0; i++) {

    var p = '';

    for (var j = 0; j < unit[1].length && n > 0; j++) {

      p = digit[n % 10] + unit[1][j] + p;

      n = Math.floor(n / 10);

    }

    s = p.replace(/(零.)*零$/, '').replace(/^$/, '零') + unit[0][i] + s;

  }

  return head + s.replace(/(零.)*零元/, '元')

  .replace(/(零.)+/g, '零')

  .replace(/^整$/, '零元整');

};

console.log(digitUppercase(7682.01)); //柒仟陆佰捌拾贰元壹分

console.log(digitUppercase(7682)); //柒仟陆佰捌拾贰元整

console.log(digitUppercase(951434677682.00)); //玖仟伍佰壹拾肆亿叁仟肆佰陆拾柒万柒仟陆佰捌拾贰元整
