I have a text input that I’m validating with regular expression, the expression rule is the following: it starts with a number between 0 and 2 and then 6 more random numbers, but I don’t know why it doesn’t work.

<input pattern="^[0-2][0-9]{6}$" required type="text" class="form-control"/>

Follow the whole page code..

    It works for me... https://jsfiddle.net/aLrff0j2/ what’s the problem you’re having?

  • when I type for example 2155898 it shows error message even if it is in the default.

    In fact, when I tested your example, it also worked... https://jsfiddle.net/aLrff0j2/1/

    @user37750 What browser you are using?

  • I’m using Google Chrome.

  • I just tested it on the mozzarella and gave it the same mistake

  • Have you ever tried to create a separate page, just with this input, to verify this error?

  • I tried it on a separate page and it worked, thanks for the tip.

  • So we already know that the problem is in the middle of your code, I can’t imagine what it is, but you could post it, just what you think might be causing it, so we can analyze it.

  • posted all the page code

  • Just one question, the error you refer to is the factor of not being able to submit the form even with valid numbers?

  • yes it is that mistake

  • I copied your code, and Linkei the bootstrap, and the login form works normally... Look: http://s12.postimg.org/e52avc8dp/Captura_de_Tela_12.png

  • It worked for me here too

  • Your answer to Samir Braga’s question shows that you did not add the "POST" method to the form tag.

You need to set the first digit as below:

pattern="^[0-2]{1}[0-9]{6}$"
