Question

我需要用文字换算金额。例如，我将从服务中获得的金额是9876，我需要在表格中显示“九千八百七十六”表。

我需要使用angularjs来做到这一点。请帮帮我怎样才能做到这一点。

function convertNumberToWords(amount) {
    var words = new Array();
    words[0] = '';
    words[1] = 'One';
    words[2] = 'Two';
    words[3] = 'Three';
    words[4] = 'Four';
    words[5] = 'Five';
    words[6] = 'Six';
    words[7] = 'Seven';
    words[8] = 'Eight';
    words[9] = 'Nine';
    words[10] = 'Ten';
    words[11] = 'Eleven';
    words[12] = 'Twelve';
    words[13] = 'Thirteen';
    words[14] = 'Fourteen';
    words[15] = 'Fifteen';
    words[16] = 'Sixteen';
    words[17] = 'Seventeen';
    words[18] = 'Eighteen';
    words[19] = 'Nineteen';
    words[20] = 'Twenty';
    words[30] = 'Thirty';
    words[40] = 'Forty';
    words[50] = 'Fifty';
    words[60] = 'Sixty';
    words[70] = 'Seventy';
    words[80] = 'Eighty';
    words[90] = 'Ninety';
    amount = amount.toString();
    var atemp = amount.split(".");
    var number = atemp[0].split(",").join("");
    var n_length = number.length;
    var words_string = "";
    if (n_length <= 9) {
        var n_array = new Array(0, 0, 0, 0, 0, 0, 0, 0, 0);
        var received_n_array = new Array();
        for (var i = 0; i < n_length; i++) {
            received_n_array[i] = number.substr(i, 1);
        }
        for (var i = 9 - n_length, j = 0; i < 9; i++, j++) {
            n_array[i] = received_n_array[j];
        }
        for (var i = 0, j = 1; i < 9; i++, j++) {

                if (n_array[i] == 1) {
                    n_array[j] = 10 + parseInt(n_array[j]);
                    n_array[i] = 0;
                }
            }
        }
        value = "";
        for (var i = 0; i < 9; i++) {
            if (i == 0 || i == 2 || i == 4 || i == 7) {
                value = n_array[i] * 10;
            } else {
                value = n_array[i];
            }
            if (value != 0) {
                words_string += words[value] + " ";
            }
            if ((i == 1 && value != 0) || (i == 0 && value != 0 && n_array[i + 1] == 0)) {
                words_string += "Crores ";
            }
            if ((i == 3 && value != 0) || (i == 2 && value != 0 && n_array[i + 1] == 0)) {
                words_string += "Lakhs ";
            }
            if ((i == 5 && value != 0) || (i == 4 && value != 0 && n_array[i + 1] == 0)) {
                words_string += "Thousand ";
            }
            if (i == 6 && value != 0 && (n_array[i + 1] != 0 && n_array[i + 2] != 0)) {
                words_string += "Hundred and ";
            } else if (i == 6 && value != 0) {
                words_string += "Hundred ";
            }
        }
        words_string = words_string.split("  ").join(" ");
    }
    return words_string;
}

<input type="text" name="number" placeholder="Number OR Amount" onkeyup="word.innerHTML=convertNumberToWords(this.value)" />
<div id="word"></div>

我提到这个javascript小提琴。但我想在一个angularjs中。

Answer 1

我将此用于Angular 8。输入：123456789.09 输出：1,2千万三十四万五千六百七十七八十九点零九

n: string;
a = ['zero ', 'one ', 'two ', 'three ', 'four ', 'five ', 'six ', 'seven ', 'eight ', 'nine ', 'ten ', 'eleven ', 'twelve ', 'thirteen ', 'fourteen ', 'fifteen ', 'sixteen ', 'seventeen ', 'eighteen ', 'nineteen '];
b = ['', '', 'twenty', 'thirty', 'forty', 'fifty', 'sixty', 'seventy', 'eighty', 'ninety'];
 
 ngOnInit(): void {
        console.log(this.inWords(123456789.09));
 }

inWords (num): string {
    num = Math.floor(num * 100);
    if ((num = num.toString()).length > 11) { return 'overflow'; }
   let n;
   n = ('00000000' + num).substr(-11).match(/^(\d{2})(\d{2})(\d{2})(\d{1})(\d{2})(\d{1})(\d{1})$/);
        if (!n) { return; } let str = ''; 

     // tslint:disable-next-line:triple-equals
     str += (n[1] != 0) ? (this.a[Number(n[1])] || this.b[n[1][0]] + ' ' + this.a[n[1][1]]) + 'crore ' : '';
     // tslint:disable-next-line:triple-equals
        str += (n[2] != 0) ? (this.a[Number(n[2])] || this.b[n[2][0]] + ' ' + this.a[n[2][1]]) + 'lakh ' : '';
     // tslint:disable-next-line:triple-equals
     str += (n[3] != 0) ? (this.a[Number(n[3])] || this.b[n[3][0]] + ' ' + this.a[n[3][1]]) + 'thousand ' : '';
     // tslint:disable-next-line:triple-equals
     str += (n[4] != 0) ? (this.a[Number(n[4])] || this.b[n[4][0]] + ' ' + this.a[n[4][1]]) : 'hundred';
     // tslint:disable-next-line:triple-equals
     str += (n[5]) ? (this.a[Number(n[5])] || this.b[n[5][0]] + ' ' + this.a[n[5][1]]) : '';
     // tslint:disable-next-line:triple-equals
     str += (n[6]) ?  ((str != '') ? 'point ' : '') + (this.a[Number(n[6])] || this.b[n[6][0]] + ' ' + this.a[n[6][1]]) : '';
     // tslint:disable-next-line:triple-equals
     str += (n[7] != 0) ? (this.a[Number(n[7])] || this.b[n[7][0]] + ' ' + this.a[n[7][1]]) : '';

     return str;
    }

定义过滤器以将数字转换为单词，例如以下代码：

angular.module('myModuleName')

.filter('convertToWord', function() {
    return function(amount) {
        var words = new Array();
        words[0] = '';
        words[1] = 'One';
        words[2] = 'Two';
        words[3] = 'Three';
        words[4] = 'Four';
        words[5] = 'Five';
        words[6] = 'Six';
        words[7] = 'Seven';
        words[8] = 'Eight';
        words[9] = 'Nine';
        words[10] = 'Ten';
        words[11] = 'Eleven';
        words[12] = 'Twelve';
        words[13] = 'Thirteen';
        words[14] = 'Fourteen';
        words[15] = 'Fifteen';
        words[16] = 'Sixteen';
        words[17] = 'Seventeen';
        words[18] = 'Eighteen';
        words[19] = 'Nineteen';
        words[20] = 'Twenty';
        words[30] = 'Thirty';
        words[40] = 'Forty';
        words[50] = 'Fifty';
        words[60] = 'Sixty';
        words[70] = 'Seventy';
        words[80] = 'Eighty';
        words[90] = 'Ninety';
        amount = amount.toString();
        var atemp = amount.split(".");
        var number = atemp[0].split(",").join("");
        var n_length = number.length;
        var words_string = "";
        if (n_length <= 9) {
            var n_array = new Array(0, 0, 0, 0, 0, 0, 0, 0, 0);
            var received_n_array = new Array();
            for (var i = 0; i < n_length; i++) {
                received_n_array[i] = number.substr(i, 1);
            }
            for (var i = 9 - n_length, j = 0; i < 9; i++, j++) {
                n_array[i] = received_n_array[j];
            }
            for (var i = 0, j = 1; i < 9; i++, j++) {
                if (i == 0 || i == 2 || i == 4 || i == 7) {
                    if (n_array[i] == 1) {
                        n_array[j] = 10 + parseInt(n_array[j]);
                        n_array[i] = 0;
                    }
                }
            }
            value = "";
            for (var i = 0; i < 9; i++) {
                if (i == 0 || i == 2 || i == 4 || i == 7) {
                    value = n_array[i] * 10;
                } else {
                    value = n_array[i];
                }
                if (value != 0) {
                    words_string += words[value] + " ";
                }
                if ((i == 1 && value != 0) || (i == 0 && value != 0 && n_array[i + 1] == 0)) {
                    words_string += "Crores ";
                }
                if ((i == 3 && value != 0) || (i == 2 && value != 0 && n_array[i + 1] == 0)) {
                    words_string += "Lakhs ";
                }
                if ((i == 5 && value != 0) || (i == 4 && value != 0 && n_array[i + 1] == 0)) {
                    words_string += "Thousand ";
                }
                if (i == 6 && value != 0 && (n_array[i + 1] != 0 && n_array[i + 2] != 0)) {
                    words_string += "Hundred and ";
                } else if (i == 6 && value != 0) {
                    words_string += "Hundred ";
                }
            }
            words_string = words_string.split("  ").join(" ");
        }
        return words_string;
    };
});

然后在您的模板（视图）中使用此过滤器，如下所示：

{{amount | converToWord}}

例如，在输入字段中显示插入的值：

<input type="text" name="number" placeholder="Number OR Amount" ng-model="myValue" />
<div id="word">{{myValue | convertToWord}}</div>
