jQuery输入数字将波斯/阿拉伯数字转换为英文数字 [英] jQuery input number convert Persian/Arabic numbers to English numbers

问题描述

我有一个数字类型的输入字段.我也想在此字段中接受波斯/阿拉伯数字.我想使用jQuery将这些数字转换为英文，但看来我无法检索这些值.

I have a input field of type number. I want to accept Persian/Arabic numbers as well in this field. I wanted to convert these numbers to English using jQuery, but it seems I can't retrieve these values.

jQuery('input[type="number"]').on('input', function() {
    console.log(jQuery(this).val());
});

对于非英文数字，​​val()为空字符串.如果该值不是英文数字，​​有什么方法可以获取数字输入字段的值?

For non-English numbers val() is empty string. Is there any way to get the value of a number input field, if the value is not a English number?

更新:

波斯数字是: 英文数字为:0 1 2 3 4 5 6 7 8 9

Persian numbers are: ۰ ۱ ۲ ۳ ۴ ۵ ۶ ۷ ۸ ۹ English numbers are: 0 1 2 3 4 5 6 7 8 9

UPDATE2:

貌似Firefox返回正确的val，但Chrome返回空字符串.所以我的问题适用于Google Chrome.

Looks like Firefox returns the correct val but Chrome returns empty string. So my question is applicable on Google Chrome.

推荐答案

您可以使用以下功能:

function toEnglishNumber(strNum) {
        var pn = ["۰", "۱", "۲", "۳", "۴", "۵", "۶", "۷", "۸", "۹"];
        var en = ["0", "1", "2", "3", "4", "5", "6", "7", "8", "9"];
        var an = ["٠", "١", "٢", "٣", "٤", "٥", "٦", "٧", "٨", "٩"];
        var cache = strNum;
        for (var i = 0; i < 10; i++) {
            var regex_fa = new RegExp(pn[i], 'g');
            var regex_ar = new RegExp(an[i], 'g');
            cache = cache.replace(regex_fa, en[i]);
            cache = cache.replace(regex_ar, en[i]);
        }
        return cache;
    }
