jQuery：如何限制字符数？

Question

I am writing an application which generates a price for something. Lets say we get an output like this:

24543.66666667 €

What does the jQuery function need to look like for achieving the following format:

24.543,66 €

?

(please note that the dot in the first price needs to be replaced by a comma)

Answer 1

Check out the Number format

The formatting and rounding you asked can be done like this:

var nb = new Number(24543.6666667);
var result = Number(nb.toFixed(2)).toLocaleString("nl-NL");

note that i've used the Dutch locale because this locale is using the , and . signs as you wanted. This can be used with any locale you want though.
