JavaScript：toLocaleString()

Question

My JavaScript toLocaleString() is doing something strange here. If I have a number less than 1000, it will give dot as decimal delimiter, but if I have a number more than 1000, it will give me comma as decimal delimiter.

My locale setting uses dot as thousand delimiter and comma as decimal delimiter.

This is how I use the code:

sellingPrice.toLocaleString(undefined, { minimumFractionDigits: 2 }

If sellingPrice is 700 , it will give me 700.00 If sellingPrice is 7000 , it will give me 7.000,00

But the result is the same

Why is this happening?

Answer 1

I just found out that javascript is following the browser locale.

In my case I use chrome. I have to change the language to my language (Indonesia) to achieve my goal, which is a bit disappointing. I want my browser language to be English.

I cannot use "en" or "de" because I want the code to be dynamic and follows the user locale.

Answer 2

var sellingPrice=700;sellingPrice.toLocaleString('en-us', { minimumFractionDigits: 2 });

will give you the result 700.00

and

var sellingPrice=7000;sellingPrice.toLocaleString('en-us', { minimumFractionDigits: 2 });

will give you the result 7,000.00
