在 SAPUI5 中为货币使用格式化程序 [英] Using a Formatter for the Currencies in SAPUI5

问题描述

我想构建自己的格式化程序，以按不同货币显示金额.

I want to build my own formattor for displaying the amount as it should in the different currencies.

有人可能猜到我使用了这个我已经知道的解决方案:

One could guess I use this solution I already know:

                                               <t:template>
                                <Text text="{
                                                parts: [
                                                    {path: 'amount'},
                                                    {path: 'currency'}
                                                ],
                                                type:'sap.ui.model.type.Currency',
                                                formatOptions: {
                                                    currencyCode: false
                                                }
                                            }"
             </t:template>

这个解决方案的问题是我已经在一个单独的列中显示了货币，如果我使用这个解决方案，它看起来很丑......

the problem with this solution is I already show the currency in a seperate column and if I go with this solution it looks pretty ugly....

所以我尝试了这个:

<t:template>
                                <Text text="{parts: [                
                                {path: 'amount'},
                                {path: 'currency'}
                                ],               
                                formatter : '.formatter.currency'}"
                                 />
                            </t:template>

我的格式化程序函数如下所示:

and my formatter function looks like this:

    currency: function(amount, currency) {

        var change = [];
        change.push(amount);
        change.push(currency);
        var sInternalType = "";
        var amount1 = new sap.ui.model.type.Currency();


            amount1.formatValue(change, sInternalType);
            return amount1;
    }

在这里，我猜我做错了一些事情，因为英语不是我的第一语言，我可能会认为我没有正确理解 API 参考，正如他们所说的那样:

Here I would guess I do something completely wrong, as English is not my first language I would probably assume I didnt understood the API References right, as they is stated this:

• formatValue(vValue, sInternalType): 任意
• 将包含金额和货币代码的给定数组格式化为字符串类型的输出值.Currency 类型不支持除 'string' 之外的其他内部类型.如果已为此类型定义了源格式，则 formatValue 也接受字符串值作为输入，该值将使用源格式解析为数组.如果 aValues 未定义或为 null，则返回 null.
• 参数:
• {array|string} vValue 要格式化的值数组或字符串值
• {string} sInternalType 目标类型
• 返回:
• {any} 格式化输出值

推荐答案

如果您打算不显示货币符号或代码，因为您已经在其他地方显示了它，您可以简单地将 showMeasure 设置为false，例如:

If it is your intention not to show the currency symbol or code because you already show it elsewhere, you could simply set showMeasure to false, e.g.:

<Text xmlns:core="sap.ui.core"
  core:require="{ CurrencyType: 'sap/ui/model/type/Currency' }"
  text="{
    parts: [
      'amount',
      'currency'
    ],
    type: 'CurrencyType',
    formatOptions: {
      showMeasure: false
    }
  }"
/>

不显示货币代码/符号是标准货币类型的一项功能.您不需要扩展它.

Not showing the currency code/symbol is a feature of the standard Currency type. You don't need to extend it.

注意:对于 OData V4，需要类型 sap/ui/model/odata/type/Currency.

Note: In case of OData V4, require the type sap/ui/model/odata/type/Currency instead.
