Why do I fill out the form, but the validator still swears?

Question

JavaScript

There is this html:

<div class="input-wrap f_left">
            <input type="text" name="number" class="number" form="dish" placeholder="Телефон">
          </div>

jQuery:

rules: {

      'number': {
        required: true
      }
    }

I will be grateful

+, (, ), - are not numbers. as far as I understood from the screenshot. If you dig further, you need regular arrangements in the front and checks on the back.
