Localization of input type number

Question

I work on a web application running in Chrome, where I have inputs with type number. In my locale commas are used for decimal numbers and a space is used for th

Answer 1

If you don't need the up/down ticks, than follow workaround can help:

for german comma (,) only:

<input type="text" pattern="[0-9]+([,][0-9]{1,2})?" name="amount">

dot (.) only:

<input type="text" pattern="[0-9]+([\.][0-9]{1,2})?" name="amount">

both but don't together: (no 1000 seperator)

<input type="text" pattern="[0-9]+([\.|,][0-9]{1,2})?" name="amount">

otherwise number for German/Deutsch:

<input name="myinput" value="0" step="0.01" lang="de-DE" type="number">

and style it with:

input[type=number] {
    -moz-appearance:textfield;
    -webkit-appearance: none;
    appearance: textfield;
}

Answer 2

Unfortunately these characters are not allowed in the <input type="number">

See the specs here : http://w3c.github.io/html-reference/datatypes.html#common.data.float-def

Is this the format you want ? http://jsfiddle.net/S8rqY/

Answer 3

The HTML5 input type=number is inadequate from the localization point of view, due to both the definition and the implementations. It is meant to be localized but as per the locale of the browser, which you cannot set or even know as a designer/author.

On my Chrome, the input type=number step=0.001 accepts 1,2 (with comma) and sends it as 1.2 and it accepts 1.200 (with a period), visibly converting it to 1200 and sending as such. This is how things are meant to be, more or less, when the browser locale is Finnish. But it fails to accept 1 200 (which is standard way of writing 1200 in Finnish) and instead sends just the digit 1.

So it’s rather hopeless. Use whatever JavaScript widgets you can find, or a simple text input box. Anything is probably better than input type=number unless all users use browsers with the same locale and have the same expectations on the format of numbers.

The spec is clear: only a period is allowed as the decimal separator. Its up to the browsers to provide localization support for forms. Thousand separators are not allowed.
