html - HTML5 input box with type="number" does not accept comma in Chrome browser

Question

I am using a HTML5 input box with type="number". Regarding to some documentations, it should be possible to enter a number with comma (not with period) if I also use the lang="" attribute. It is working in Firefox, but not in Chrome (does not accept a comma). How can I get Chrome to accept the comma in the input box. My problem is that our German users expect that they can enter a comma instead of a period there.

Please enter a number with comma: <br/>
<input id="num" type="number" step="any" lang="de" pattern="-?[0-9]+[,.]*[0-9]+" /> 

Answer 1

actually, if i read the documentation correctly, pattern is not supported for type=number. hence, stick to type=text and then add pattern="..." for the front end validation. in the next step, you will then need to convert the text input into a real number if it wasn't compatible to JavaScript/computing format.

2017 and still no good solution for this common problem...
