Is there a way to set the minimum and maximum length of 15 numbers (only numbers) in my form field?

I tried:

Try

\d → for numbers

pattern="\d{15,15}"

Update on s1lence comments

pattern="\d{15}"

Update to install Custom Validation Message

Add this attribute to the input field.

oninvalid="this.setCustomValidity('15 digit number needed')"

Use as a comment on Yucca C. Corpel (check the script above for a working demo)

title="Exactly 15 digits"

Try the following:

pattern = /[0-9]{15}/

You can also do it like this.

<input title="requires exactly 15 digits" maxlength="15" pattern=".{15}" required />
