How do you deal with decimal (,) and javascript?

Question

I've an ASP.NET MVC application, C# , and some numbers into my Model in decimal type, which treat the fractional part as comma (ie 12,5).

I serialize them and send to the client using JSON , which correctly convert the comma to point:

var result = Json(new { Value = myModel.myValue }); // become Value = 12.5

Than I process the data client side, with some math function, getting the number value always with point (ie 12.5 * 3 = 37.5).

But, when I need to post back to the server the processed value, if I keep the point and I store the value into my Model (which is decimal , as said), it truncate the values after the point.

Do I really need to do result.replace('.', ',') before sending back data client side? Damn not so good. Best practices?

The paradox is that for mvc's jquery validator (being decimal required) I need to print the value into the input box with comma. The round-trip is crazy...

Answer 1

您可以使用stringify将JavaScript对象转换为字符串，

var myJSON = JSON.stringify(Yourvalue);

Answer 2

This may be helpful, rather than burdening the server with the client's wild choice of encoding, get the javascript to do it.

It nicely turns 98.76 into 98,76 when passing it through 'it-IT'
