javascript - 将数值(金额)转换为文本 angularjs

Question

我正在使用 angularJS 在 mvc-5 中创建一个基于 Web 的应用程序，我在表中得到了金额总和

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

我像这样从 Controller 获取金额

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

这里我想将金额从数字转换为文本。例如，如果总数为 4526，则应显示 四千五百二十六。

Answer 1

您可以将数字转换为单词，就像 this 中所做的那样回答。

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 View 中，使用 totalAmountInWords 而不是 totalAmount。

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