Restrict input field to two decimals with jQuery

Question

I have an input field which I want to restrict so that the user only can input a number with the maximum of two decimals. Want to do this using jQuery.

Could I use j

Answer 1

An alternative approach with a regular expression:

    $('#id').on('input', function () {
        this.value = this.value.match(/^\d+\.?\d{0,2}/);
    });

The id selector can be replaced by a css selector.
