Orbeon 中美元和美分字段的格式输出

Question

我如何指定要保存两个其他字段之和的字段应该能够以美元和美分的形式显示高于 $999.999.99 的值？

表单源代码如下。

当我测试表单时，我在 amount_1 中输入 999999.99，它显示 $999,999.99。我在 amount_2 中输入 .01。 total_amount 字段显示 $1.0E。我希望它显示 $1,000,000.00 并给出一个缺失或不正确的值错误。

我曾尝试使用文本输出控件，但遇到了同样的问题。

我正在编写一个银行应用程序，它使用 Form Runner 向银行代理请求数据，因此浮点字段不够准确。

我查看了几篇似乎与格式化输出相关的帖子，但没有看到任何帮助。我正在使用各种数据类型的默认输出格式。

感谢您的帮助。

Answer 1

使用xforms:output 并使用类似这样的格式设置值。

<xforms:output bind="total_amount-bind" xxforms:format="format-number(., $ ###,###.##)" />
