Angular指令/服务将数字转换为单词(在Angularjs中需要)？

我想把数字转换成单词.像234中的单词将是2,334.同样1000将是一千.同样100意味着100.

在angularjs中是否有任何库.如果那时我们将如何在angularjs指令/服务中写入,以便我们可以再次使用它.

创建一个单词过滤器.

我从这篇博文中得到了"toWords"算法:http://ravindersinghdang.blogspot.com/2013/04/convert-numbers-into-words-using.html

var app = angular.module('app',[]);

app.filter('words', function() {
  function isInteger(x) {
        return x % 1 === 0;
    }

  
  return function(value) {
    if (value && isInteger(value))
      return  toWords(value);
    
    return value;
  };

});


var th = ['','thousand','million', 'billion','trillion'];
var dg = ['zero','one','two','three','four', 'five','six','seven','eight','nine']; 
var tn = ['ten','eleven','twelve','thirteen', 'fourteen','fifteen','sixteen', 'seventeen','eighteen','nineteen'];
var tw = ['twenty','thirty','forty','fifty', 'sixty','seventy','eighty','ninety']; 


function toWords(s)
{  
    s = s.toString(); 
    s = s.replace(/[\, ]/g,''); 
    if (s != parseFloat(s)) return 'not a number'; 
    var x = s.indexOf('.'); 
    if (x == -1) x = s.length; 
    if (x > 15) return 'too big'; 
    var n = s.split(''); 
    var str = ''; 
    var sk = 0; 
    for (var i=0; i < x; i++) 
    {
        if ((x-i)%3==2) 
        {
            if (n[i] == '1') 
            {
                str += tn[Number(n[i+1])] + ' '; 
                i++; 
                sk=1;
            }
            else if (n[i]!=0) 
            {
                str += tw[n[i]-2] + ' ';
                sk=1;
            }
        }
        else if (n[i]!=0) 
        {
            str += dg[n[i]] +' '; 
            if ((x-i)%3==0) str += 'hundred ';
            sk=1;
        }


        if ((x-i)%3==1)
        {
            if (sk) str += th[(x-i-1)/3] + ' ';
            sk=0;
        }
    }
    if (x != s.length)
    {
        var y = s.length; 
        str += 'point '; 
        for (var i=x+1; i
