以角度格式化数字到货币格式

问题描述 投票:1回答:3

我想将数字转换为数字格式。

到目前为止我试过这个:http://plnkr.co/edit/lVJGXyuX0BMvB9QUL5zS?p=preview

function formatMoney(credits) {

    console.log(credits+'credits');
    var lastThree = credits.substring(credits.length-3);
    // var lastThree = credits.slice(-2);
    var otherNumbers = credits.substring(0,credits.length-3);
    console.log(otherNumbers+'otherNumbers');
    if(otherNumbers !== '')
        lastThree = ',' + lastThree;
    var res = otherNumbers.replace(/\B(?=(\d{2})+(?!\d))/g, ",") + lastThree;
    return res;
  }

function formatNumber(num) {
    var n1, n2;
    num = (Math.round(num * 100) / 100) + '' || '';
    n1 = num.split('.');
    n2 = n1[1] || null;
    n1 = n1[0].replace(/(\d)(?=(\d\d)+\d$)/g, ",");
    num = n2 ? n1 + '.' + n2 : n1;
    return num;
  }

我想将数字转换为印度货币。

例:

1,000
10,000
1,00,000
10,00,000

我通过函数formatMoney()获得的输出:1,0,0,000

函数formatNumber()得到的输出:1000,按0后,它变为NaN0

我在这做错了什么?

AngularJS提供商用于做这些事情的过滤器,有一个currency filter可用:

我已经删除了格式化函数并用货币过滤器和印度货币的卢比符号替换了你的代码,希望这能解决你的问题。

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

app.controller('MainCtrl', function($scope) {
  
  $scope.change=function($event, money){
      $scope.money = qwerty;
    };
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<!DOCTYPE html>
<html ng-app="plunker">

  <head>
    <meta charset="utf-8" />
    <title>AngularJS Plunker</title>
    <script>document.write('<base href="' + document.location + '" />');</script>
    <link rel="stylesheet" href="style.css" />
    <script data-require="[email protected]" src="https://code.angularjs.org/1.2.20/angular.js" data-semver="1.2.20"></script>
    <script src="app.js"></script>
  </head>

  <body ng-controller="MainCtrl">
    <input  ng-keypress="change($event, money)" type="text" ng-model='money' >
    <pre>{{money | currency : "&#8377;" }}</pre>
  </body>

</html>

你不需要角度来做这个,因为核心Javascript Intl中有一个api。

var number = 2453413.70;

console.log(new Intl.NumberFormat('en-IN', { style: "currency", currency: "INR" }).format(number));

如果您不想要货币符号,请像这样使用它

console.log(new Intl.NumberFormat('en-IN').format(number));

您可以直接将$filter服务注入并使用到您的控制器甚至您的视图中

var myApp = angular.module('myApp', []);
myApp.controller('CalcCtrl', function ($scope, $filter) {
    $scope.num = 122212111221121212;
    $scope.filtered = $filter('currency')($scope.num);
    alert($scope.filtered)
});

请记住,$ filter服务也很容易扩展。

myApp.filter('customCurrency', function() { 

    return function(input, symbol, place) {

    // Ensure that we are working with a number
    if(isNaN(input)) {
      return input;
    } else {

      // Check if optional parameters are passed, if not, use the defaults
      var symbol = symbol || 'EUROS';
      var place = place === undefined ? true : place;

      // Perform the operation to set the symbol in the right location
      if( place === true) {
        return symbol + input;
      } else {
        return input + symbol;
      }

    }
  }

});

myApp.controller('CalcCtrl', function ($scope, $filter) {
    $scope.num = 122212111221121212;
    $scope.filtered = $filter('customCurrency')($scope.num);
});
