如何格式化输入到HTML文本字段中的文本，如货币？ [英] How can I format the text entered into an HTML textfield like currency?

问题描述

我有一系列texfields，我想格式化为货币。优选地，这将在飞行中完成，但是至少开启。我的意思是货币格式是349507 - > 349,507美元。可能吗？

I have a series of texfields, which I'd like to format as currency. Preferably, this would be done on the fly but at least onblur. What I mean by currency format is 349507 -> $349,507. Is it possible?

我更喜欢HTML / CSS / JS解决方案，因为我需要更少的解释。我对jQuery不熟悉。

I prefer HTML/CSS/JS solutions, because I need less explanation. I'm not familiar at all with jQuery.
