将数字转换为单词的 Angular 指令/服务(Angularjs 中需要)? [英] Angular directive/service to convert number into words (need in Angularjs)?

问题描述

我想将数字转换为单词.就像单词中的 234 将是 234.同样，1000 将是一千.同样，100 表示一百.

angularjs 中有没有这方面的库.如果那么我们将如何在 angularjs 指令/服务中编写以便我们可以再次使用它..

解决方案

创建单词过滤器.

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() {函数 isInteger(x) {返回 x % 1 === 0;}返回函数(值){if (value && isInteger(value))返回词(值)；返回值；};});var th = ['','千','百万','十亿','万亿'];var dg = ['零','一','二','三','四','五','六','七','八','九'];var tn = ['十','十一','十二','十三','十四','十五','十六','十七','十八','十九'];var tw = ['二十','三十','四十','五十','六十','七十','八十','九十'];函数 toWords(s){s = s.toString();s = s.replace(/[\, ]/g,'');if (s != parseFloat(s)) 返回不是数字"；var x = s.indexOf('.');如果 (x == -1) x = s.length;如果 (x > 15) 返回太大"；var n = s.split('');var str = '';无功 sk = 0;for (var i=0; i

I want to convert number into words. Like 234 in word would be 2 hundred thirty-four. Similarly 1000 will be one thousand. Similarly 100 means one hundred.

Is there any library for this in angularjs. If then how we will write in angularjs directive/service so that we can use it again..

解决方案

Create a words filter.

I got the "toWords" algorithm from this blog post: 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<y; i++) str += dg[n[i]] +' ';
    }
    return str.replace(/\s+/g,' ');
}

window.toWords = toWords;

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.js"></script>

<div ng-app="app">
  
  <input type="text" ng-model="name" /> {{name | words}}
</div>
