The toLocaleString()method is by definition implementation-dependent: it uses the implementation locale, such as browser locale. So if I were looking at your page that uses the method, I would see numbers formatted according to Finnish or English locale, depending on which browser I'm using.
根据toLocaleString()定义，该方法依赖于实现：它使用实现区域设置，例如浏览器区域设置。因此，如果我正在查看使用该方法的页面，我会看到根据芬兰语或英语语言环境格式化的数字，具体取决于我使用的浏览器。
What you want is localization by the locale of the page, and for this you need something else. In simple cases you might code it yourself, but number formatting is in general complicated, making it reasonable to use a library, such as Globalize. Check out the compact source of a simple demo. In Globalize, you use standard language codeswhen specifying the locale.
您想要的是按页面的语言环境进行本地化，为此您需要其他东西。在简单的情况下，您可以自己编写代码，但数字格式通常很复杂，因此使用诸如Globalize 之类的库是合理的。查看一个简单演示的紧凑源代码。在 Globalize 中，您在指定区域设置时使用标准语言代码。

Internationalization is always challenging and unfortunately there doesn't seem to be a consistent/pervasive solution to it. Your best bet is to use a 3rd party library to take care of things for you. We rely heavily on googles closure library, which has some pretty powerful i18n (internationalization) tools. Take a look at http://www.daveoncode.com/2009/11/26/goog-i18n-numberformat-formatting-number-locale-string/for an example of how to use it. In the end, it becomes as easy as:

// define italian number format symbols
goog.i18n.NumberFormatSymbols = goog.i18n.NumberFormatSymbols_it_IT;
// create new decimal formatter (PERCENT, CURRENCY, SCIENTIFIC are options)
formatter = new goog.i18n.NumberFormat(goog.i18n.NumberFormat.Format.DECIMAL);
// view formatted and localized string
alert(formatter.format(15650.579));
If you are new to closure, don't worry. It's not hard to get set up and has a multitude of excellent helper classes that you may find useful. http://code.google.com/closure/library/docs/gettingstarted.html
如果您不熟悉关闭，请不要担心。设置起来并不难，并且有许多优秀的帮助类，您可能会发现它们很有用。 http://code.google.com/closure/library/docs/gettingstarted.html

The JavaScript internationalization support is quite poor (as you have discovered). You might take a look at https://github.com/jquery/globalizeIt handles number formatting, and also dates, times, currencies.
JavaScript 国际化支持很差（如您所见）。你可以看看https://github.com/jquery/globalize它处理数字格式，还有日期、时间、货币。

A bit of voodoo can implement your own number formatting. You could build this into String.prototype, but I didnt want that, since its localized.
一点伏都教可以实现您自己的数字格式。你可以将它构建到 String.prototype 中，但我不想要那个，因为它是本地化的。
function reverse(str) {
return str.split('').reverse().join('');
}
function num2str(num) {
var str = num+"";
// european
// return reverse(reverse(str.replace('.',',')).replace(/\d{3}/g,'$&.').replace(/\.$/,''));
// american
return reverse(reverse(str).replace(/\d{3}/g,'$&,').replace(/\,$/,''));
}
and then its
然后它的

> 25,000.45
