将数值(数量)转换为文本角度

Question

我正在使用angularJS在mvc-5中创建一个基于web的应用程序，我在我的表中得到了一个金额总和

<td><span style="font-weight:bolder; font-size:24px; float:right;">Total: {{totalAmount}}</span></td>

我像这样从控制者那里获取数量

$scope.totalAmount = 0;
$scope.tableindiv2.forEach(function (t) {
   $scope.totalAmount += Number(t.amount);
   $scope.empnameandaddress();
});

这里我想将数量从数字转换为文本。例如，如果总数为4526，则应显示four thousand five hundred twenty six。

Answer 1

您可以像this answer中的done那样将数字转换为单词。

var a = ['','one ','two ','three ','four ', 'five ','six ','seven ','eight ','nine ','ten ','eleven ','twelve ','thirteen ','fourteen ','fifteen ','sixteen ','seventeen ','eighteen ','nineteen '];
var b = ['', '', 'twenty','thirty','forty','fifty', 'sixty','seventy','eighty','ninety'];

function inWords (num) {
    if ((num = num.toString()).length > 9) return 'overflow';
    n = ('000000000' + num).substr(-9).match(/^(\d{2})(\d{2})(\d{2})(\d{1})(\d{2})$/);
    if (!n) return; var str = '';
    str += (n[1] != 0) ? (a[Number(n[1])] || b[n[1][0]] + ' ' + a[n[1][1]]) + 'crore ' : '';
    str += (n[2] != 0) ? (a[Number(n[2])] || b[n[2][0]] + ' ' + a[n[2][1]]) + 'lakh ' : '';
    str += (n[3] != 0) ? (a[Number(n[3])] || b[n[3][0]] + ' ' + a[n[3][1]]) + 'thousand ' : '';
    str += (n[4] != 0) ? (a[Number(n[4])] || b[n[4][0]] + ' ' + a[n[4][1]]) + 'hundred ' : '';
    str += (n[5] != 0) ? ((str != '') ? 'and ' : '') + (a[Number(n[5])] || b[n[5][0]] + ' ' + a[n[5][1]]) + 'only ' : '';
    return str;
}

$scope.totalAmount = 0;
$scope.tableindiv2.forEach(function (t) {
   $scope.totalAmount += Number(t.amount);
   $scope.empnameandaddress();
});

$scope.totalAmountInWords = inWords($scope.totalAmount);

在HTML视图中，使用totalAmountInWords而不是totalAmount。

style="font-weight:bolder; font-size:24px; float:right;">Total: {{totalAmountInWords }}</span></td>

Answer 2

您必须创建将数字转换为文本的word过滤器

请参考此Angular directive/service to convert number into words (need in Angularjs)?

Answer 3

我已经为Angular 8做了this。它还可以将浮点数/双精度数转换为word。
