Force decimal point instead of comma in HTML5 number input (client-side)

Question

I have seen that some browsers localize the input type=\"number\" notation of numbers.

So now, in fields where my application displays longitude and la

Answer 1

With the step attribute specified to the precision of the decimals you want, and the lang attribute [which is set to a locale that formats decimals with period], your html5 numeric input will accept decimals. eg. to take values like 10.56; i mean 2 decimal place numbers, do this:

<input type="number" step="0.01" min="0" lang="en" value="1.99">

You can further specify the max attribute for the maximum allowable value.

Edit Add a lang attribute to the input element with a locale value that formats decimals with point instead of comma

Answer 2

1) 51,983 is a string type number does not accept comma

so u should set it as text

<input type="text" name="commanumber" id="commanumber" value="1,99" step='0.01' min='0' />

replace , with .

and change type attribute to number

$(document).ready(function() {
    var s = $('#commanumber').val().replace(/\,/g, '.');   
    $('#commanumber').attr('type','number');   
    $('#commanumber').val(s);   
});

Hope this solves your Problem

Answer 3

Use lang attribut on the input. Locale on my web app fr_FR, lang="en_EN" on the input number and i can use indifferently a comma or a dot. Firefox always display a dot, Chrome display a comma. But both separtor are valid.

Answer 4

I needed to ensure values can still be entered with a comma instead of a point as a decimal separator. This seems to be an age-old problem. Background info can be found following these links:

• https://www.slightfuture.com/webdev/html5-input-number-localization.html
• https://codepen.io/aminimalanimal/full/bdOzRG

I finally solved it with a little bit of jQuery. Replacing the commas with dots onChange. This seems to be working good so far in latest Firefox, Chrome and Safari.

$('input[type=number]').each(function () {

  $(this).change(function () {

    var $replace = $(this).val().toString().replace(/,/g, '.');

    $(this).val($replace);

  })

});

Answer 5

According to the spec, You can use any as the value of step attribute:

<input type="number" step="any">

Answer 6

I found a blog article which seems to explain something related:
HTML5 input type=number and decimals/floats in Chrome

In summary:

• the step helps to define the domain of valid values
• the default step is 1
• thus the default domain is integers (between min and max, inclusive, if given)

I would assume that's conflating with the ambiguity of using a comma as a thousand separator vs a comma as a decimal point, and your 51,983 is actually a strangely-parsed fifty-one thousand, nine hundred and eight-three.

Apparently you can use step="any" to widen the domain to all rational numbers in range, however I've not tried it myself. For latitude and longitude I've successfully used:

<input name="lat" type="number" min="-90.000000" max="90.000000" step="0.000001">
<input name="lon" type="number" min="-180.000000" max="180.000000" step="0.000001">

It might not be pretty, but it works.
