It will work until you have someone from Europe get in touch early in the morning to complain your form doesn’t accept decimal commas (although they may well just roll their eyes again and mutter something about how Anglos don’t bother supporting their international users properly).

- klibertp 4y ago> I prefer doing validation in JS most of the time As you should! :) Preferably by using a parser-generator library. Validation is basically just an error mode of parsing, and parsing things with regexes is not only unreadable, but also loses a lot of valuable information about the error.
- runarberg 4y agoLuckily it is easy to do validation with javascript if you properly set type=number: if (Number.isNaN(input.valueAsNumber)) { // If only this message could also by localized input.setCustomValidity("Please type a number"); } else { input.setCustomValidity(""); } But double luckily, we don’t even need to do this as we also get this for free, and as a bonus the message is localized.
