How do I make the input [number] field accept only numbers in Firefox? In Chrome, Opera and Edge works perfectly, but in Firefox the [number] field accepts letters and spaces.
<inputtype="number" name="EstoqueProd[]" class="form-control" min="1" value="1"/>
You can force this with a keydown event handler that detects if the entered character is a digit by comparing the key code.
An example would be:
var input = document.querySelector('input[name="EstoqueProd[]"]');
input.addEventListener('keydown', function(e) {
var numero = (e.keyCode >= 48 && e.keyCode <= 57) || (e.keyCode >= 96 && e.keyCode <= 105);
var controlos = [8, 37, 39].includes(e.keyCode);
if (!numero && !controlos) return e.preventDefault();
});<input type="number" name="EstoqueProd[]" class="form-control" min="1" value="1" />jsFiddle: link
