在javascript中将本地化的字符串转换为十进制

Question

I have a decimal, that could look like 123,34 , 123123,09 , 1234 , 123.34 , 123123.09 .

My MVC application supports localization, I need to find a safe way to convert the most likely user input into a decimal. So for decimal value . will represent as , (eg 12.34 => 12,34)

I want to get this value in javascript as

var maxAmount = parseFloat("@Model.MaxAmount");

if MaxAmount is 1,25 I will get a result as 1 only.

How is that possible?

Answer 1

为什么不使用MaxAmount.ToString（CultureInfo.InvariantCulture）指定模型属性的格式-这样，十进制始终将序列化为1.25，并且仍可以由JavaScript正确解释。

Answer 2

Just do the replace for the edge case of xxx,xx :

var maxAmount = parseFloat('@Model.MaxAmount'.replace(',', '.'));

This will convert string of type "123,45" to "123.45" but keep the "123.45" in the same format.
