这是我的问题：我需要对3个输入求和，然后它们需要显示在“总计”的第四个输入中。所有这些输入的值都必须设置为货币格式。
在我所附的代码中，总和做得很好，我格式化了前三个输入而不是总输入
有人可以知道如何做吗？如何在总输入中添加格式？
谢谢！保重！

使用以下格式设置总输入值：
document.getElementById('amount').value = total.toLocaleString( "de-DE" );

我在调用输入金额时添加了此代码，它起作用了！ “ document.getElementById（'amount'）。value = total.toLocaleString（” de-DE“）;”谢谢大家
