問題描述
我將浮點數格式化為語言環境字符串(歐元)，每個瀏覽器中的結果都大不相同.沒有自己的功能可以修復嗎?
I format a float to a locale string (Euro) and there are very different results in every browser. Is it possible to fix without an own function?
var sum=2282.0000;
var formated_sum = Number(sum.toFixed(2)).toLocaleString("de-DE", {style: "currency", currency: "EUR"});
Firefox 結果:2.282,00 €
Firefox result: 2.282,00 €
Chrome 結果:2.282 €
Chrome result: 2.282 €
IE 結果:2.282,00 €
IE result: 2.282,00 €
Safari 結果:2282 歐元
Safari result: 2282 €
Safari 的結果非常錯誤，chrome 的結果并沒有那么糟糕.任何想法如何在不編寫自己的格式化函數的情況下解決這個問題?
Safari results are very much wrong, chrome results are not so much bad. Any Idea how to fix that without writing an own function for formatting?
這個問題在這里可能已經有了答案:toLocaleString() 在不同瀏覽器中的行為不一致不，我的問題不同，因為我正在尋找貨幣的解決方案，而不是日期
This question may already have an answer here: Inconsistent behavior of toLocaleString() in different browser No, my question is different because i am searching for a solution for Currency, not DATE
推薦答案
ECMA 262 指定函數依賴于實現并且不帶參數.
ECMA 262 specifies that the function is implementation dependent and takes no arguments.
產生一個字符串值，表示此數字值格式化根據宿主環境當前語言環境的約定.這個函數是依賴于實現的，它是允許的，但是不鼓勵，因為它返回與 toString 相同的東西.
Produces a String value that represents this Number value formatted according to the conventions of the host environment’s current locale. This function is implementation-dependent, and it is permissible, but not encouraged, for it to return the same thing as toString.
注意此函數的第一個參數可能用于本標準的未來版本；建議實現不會將此參數位置用于其他任何事情.
NOTE The first parameter to this function is likely to be used in a future version of this standard; it is recommended that implementations do not use this parameter position for anything else.
它也在 ECMA 國際化 API 規范中(其中Number.prototype.toLocaleString 取代 ECMA 262 但接受 2 個參數)
It is also in ECMA internationalization API specification (which for Number.prototype.toLocaleString supersedes ECMA 262 but accepts 2 arguments)
此定義取代 ES5 15.7.4.3 中提供的定義.
This definition supersedes the definition provided in ES5, 15.7.4.3.
當使用可選參數調用 toLocaleString 方法時語言環境和選項，采取以下步驟:
When the toLocaleString method is called with optional arguments locales and options, the following steps are taken:
讓 x 是這個 Number 值(在 ES5, 15.7.4 中定義).如果語言環境是未提供，則讓語言環境未定義.如果選項不是提供，然后讓選項未定義.讓 numberFormat 為創建一個新對象的結果，就像通過表達式 newIntl.NumberFormat(locales, options) 其中 Intl.NumberFormat 是11.1.3 中定義的標準內置構造函數.返回結果調用 FormatNumber 抽象操作(在 11.3.2 中定義)參數 numberFormat 和 x.長度屬性的值toLocaleString 方法為 0.
Let x be this Number value (as defined in ES5, 15.7.4). If locales is not provided, then let locales be undefined. If options is not provided, then let options be undefined. Let numberFormat be the result of creating a new object as if by the expression new Intl.NumberFormat(locales, options) where Intl.NumberFormat is the standard built-in constructor defined in 11.1.3. Return the result of calling the FormatNumber abstract operation (defined in 11.3.2) with arguments numberFormat and x. The value of the length property of the toLocaleString method is 0.
此外，mdn指定 Safari 不支持它.
Besides, mdn specifies that Safari has no support for it.
