Jquery allow only float 2 digit before and after dot

Question

i have to allow only number like these:

• 2 or 45 (from 0 to 99)
• 2.50 or 35.75 (2 digits before dot and 2 digits after)

Someone can help me? I could limit only int in this way:

$('#valueSconto').on('input', function () {
    this.value = this.value.replace(/[^0-9]/g, '');
});

Answer 1

Try setting input maxlength to 5 ; utilizing .val(function(index, val)) ; RegExp /\d{3}|[^\d{2}\.]|^\./

$("#valueSconto").on("input", function() {
  $(this).val(function(i, val) {
    return val.replace(/\d{3}|[^\d{2}\.]|^\./g, "");
  });
});

<input type="text" id="valueSconto" maxlength="5" />
