I've some issues with decimal input on iOS using the numeric keypad. I have the following HTML:

$('#number').keyup(function() {
  $('#log').prepend('<p>Input: ' + $(this).val() + '</p>');
});
<script src=".3.1/jquery.min.js"></script>
<input type="number" inputmode="decimal" id="number">
<p>
  Input as number:
  <div id="log"></div>
</p>

I've some issues with decimal input on iOS using the numeric keypad. I have the following HTML:

$('#number').keyup(function() {
  $('#log').prepend('<p>Input: ' + $(this).val() + '</p>');
});
<script src="https://cdnjs.cloudflare./ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="number" inputmode="decimal" id="number">
<p>
  Input as number:
  <div id="log"></div>
</p>

This is working as expected in Chrome browser, Android etc., but on iOS there is some issues. If I set the Region to e.g. Denmark (ma decimal seperator) but the Language to English (UK) (point decimal seperator), the number pad gives me a ma decimal seperator, but I seems that the HTML/JS does not support this. If I input e.g. 12,3 the value of the input field bees empty when I use the ma.

How can I fix this?

When Region is Denmark and Language is Danish, it's all working as expected.

The code and demo is available on this StackBlitz: https://decimal-input-ios.stackblitz.io

  • Is the issue present on a specific browser on iOS or all browser? Did you try iOS Firefox or Chrome? – 3limin4t0r Commented Jul 2, 2021 at 9:35
  • @3limin4t0r iOS always uses the same browser engine. No matter which browser you use it is always webpack. So the errors are usually there on all iOS Browsers – basti500 Commented Jul 2, 2021 at 9:38

Reset to default 2 +50

I found some workaround, you can replace , with . every time that it is being typed:

let prevNum = "";

$('#number').on("keyup", function (e) {
    if (e.keyCode == 188) {
        $(this).val(prevNum + ".");
    }
    
    prevNum = $(this).val();

    $('#log').prepend('<p>Input: ' + $(this).val() + '</p>');
});

This is a cheat, but after reading several similar posts about it, I'm not sure you have too many options. If you don't need the (usually inconsequential) up/down ticks, you can just use a 'text' input with a pattern. The pattern will tell iOS to use the number pad despite this being a 'text' input.

$('#number').keyup(function(evt) {
  $('#log').prepend('<p>Input: ' + $(this).val() + '</p>');
});
<script src="https://cdnjs.cloudflare./ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="text" inputmode="decimal" id="number" pattern="[0-9.,]+">
<p>Input as number:</p>
  <div id="log"></div>

Can you please try to add lang="en" it should change by adding a lang attribute

<input type="number" inputmode="decimal" id="number" lang="en">

I cannot test since I do not own any IOS device...

But you said:

When Region is Denmark and Language is Danish, it's all working as expected.

So why not just change the whole page language on that specific input focus and restore it on blur? That would be:

$("#number").on("focus", function(){
  $("html").attr("lang", "da");
});

$("#number").on("blur", function(){
  $("html").attr("lang", "en");
});

It worths a try ;)

Use parseFloat() to make the value a float

$('#number').keyup(function() {
  $('#log').prepend('<p>Input: ' + parseFloat($(this).val()) + '</p>');
});
<html lang="en-GB">
<script src="https://cdnjs.cloudflare./ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="number" inputmode="decimal" id="number">
<p>
  Input as number:
  <div id="log"></div>
</p>
</html>
