Input with pattern

Hello, I want to make an input that can’t be submitted if it doesn’t contain ‘+’ sign before all of content.
I want it for phone numbers.

For example,
+994551112233 - TRUE
994+551112233 - FALSE

I couldn’t do this with pattern

You’ll want to use reg exp for that.

There is no plus sign checker

What code are you using right now? As you can definitely do it using JavaScript and Regex (might be able to using HTML 5 input pattern attribute

Something like

<input type="tel" pattern="\+[0-9]{12}" />

Thank You

If you are looking for pre-made regex patterns for phone numbers (or other things) there are a few on this site:-

If you want to experiment and create you own custom regex patterns, I find this tool quite useful:-
