¿Anyone knows if pattern attribute works without js?

Question

I was wondering if the validation of the pattern attribute works in a browser that does not supports js (or has it locked).

Sorry for my bad english.

Answer 1

yeah of course, like that:
<form action="/action_page.php">
Country code: <input type="text" name="country_code"
pattern="[A-Za-z]{3}" title="Three letter country code">
<input type="submit">
</form>

Answer 2

welcome bro 💙

Answer 3

thank you :D

Answer 4

you can use pattern attribute on input elements like
<input type='text' name='age' pattern=/[0-9]{2}/ placeholder='your age'/>
html5 will validate it automatically on submission
