javascript 如何根据语言环境将字符串转换为数字（与 .toLocaleString 相反）？

How do I convert String to Number according to locale (opposite of .toLocaleString)?

提问by user2754545

If I do:

如果我做：

var number = 3500;
alert(number.toLocaleString("hi-IN"));

I will get ?,???in Hindi.

我会?,???用印地语。

But how can I convert it back to 3500. I want something like:

但是我怎样才能将它转换回3500. 我想要这样的东西：

var str='?,???';
alert(str.toLocaleNumber("en-US"));

So, that it can give 3500.

所以，它可以给3500.

Is it possible by javascript, jquery or any other free library?

是否可以通过 javascript、jquery 或任何其他免费库实现？

Above link will take you to git project page. This is a js library contributed by Microsoft. You should give it one try and try to use formt method of that plugin. If you want to study this plugin, here is the link for the same:

Use the Globalize library.

使用全球化库。

Install it

安装它

npm install globalize cldr-data --save

npm install globalize cldr-data --save

then

然后

var cldr = require("cldr-data");
var Globalize = require("globalize");

Globalize.load(cldr("supplemental/likelySubtags"));
Globalize.load(cldr("supplemental/numberingSystems"));
Globalize.load(cldr("supplemental/currencyData"));

//replace 'hi' with appropriate language tag
Globalize.load(cldr("main/hi/numbers"));
Globalize.load(cldr("main/hi/currencies"));

//You may replace the above locale-specific loads with the following line,
// which will load every type of CLDR language data for every available locale
// and may consume several hundred megs of memory!
//Use with caution.
//Globalize.load(cldr.all());

//Set the locale
//We use the extention u-nu-native to indicate that Devanagari and
// not Latin numerals should be used.
// '-u' means extension
// '-nu' means number
// '-native' means use native script
//Without -u-nu-native this example will not work
//See 
// https://en.wikipedia.org/wiki/IETF_language_tag#Extension_U_.28Unicode_Locale.29
// for more details on the U language code extension 
var hindiGlobalizer = Globalize('hi-IN-u-nu-native');

var parseHindiNumber = hindiGlobalizer.numberParser();
var formatHindiNumber = hindiGlobalizer.numberFormatter();
var formatRupeeCurrency = hindiGlobalizer.currencyFormatter("INR");

console.log(parseHindiNumber('?,???')); //3500
console.log(formatHindiNumber(3500));   //?,???
console.log(formatRupeeCurrency(3500)); //??,???.??

Unfortunately you will have to tackle the localisation manually. Inspired by this answer, I created a function that will manually replace the Hindi numbers:

不幸的是，您将不得不手动处理本地化。受到这个答案的启发，我创建了一个函数来手动替换印地语数字：

function parseHindi(str) {
    return Number(str.replace(/[??????????]/g, function (d) {
        return d.charCodeAt(0) - 2406;
    }).replace(/[??????????]/g, function (d) {
        return d.charCodeAt(0) - 2415;
    }));
}

alert(parseHindi("????"));

You can try this out

你可以试试这个

function ConvertDigits(input, source, target) {
var systems = {
    arabic: 48, english: 48, tamil: 3046, kannada: 3302, telugu: 3174, hindi: 2406,
    malayalam: 3430, oriya: 2918, gurmukhi: 2662, nagari: 2534, gujarati: 2790,
},
output = [], offset = 0, zero = 0, nine = 0, char = 0;
source = source.toLowerCase();
target = target.toLowerCase();

if (!(source in systems && target in systems) || input == null || typeof input == "undefined" || typeof input == "object") {
    return input;
}

input = input.toString();
offset = systems[target] - systems[source];
zero = systems[source];
nine = systems[source] + 9;    
for (var i = 0 ; i < input.length; i++) {
    var char = input.charCodeAt(i);
    if (char >= zero && char <= nine) {
        output.push(String.fromCharCode(char + offset));
    } else {
        output.push(input[i]);
    }
}
return output.join("");

}

}

var res = ConvertDigits('?????????', 'hindi', 'english');

var res = ConvertDigits('?????????', 'hindi', 'english');

I got it from hereIf you need a jquery thing then please try this link

我从这里得到它 如果你需要一个 jquery 的东西，那么请试试这个链接

var number = 3500;

var toLocaleString = number.toLocaleString("hi-IN")

var formatted = toLocaleString.replace(',','')

var converted = parseInt(formatted)
