title: How can I tell the validator of Vuelidate to accept "alphaNum" plus character dot(".")?
body: <p>I have an input field, I can tell <strong>Vuelidate</strong> that it only accepts <code>alphaNum</code> and <code>Required</code> like this:</p>
  
  <pre class="lang-js prettyprint-override"><code>import { required, alphaNum } from "vuelidate/lib/validators";
  
  export default {
    data() {
      return {
        myInputValue: ""
      };
    },
    validations: {
      myInputValue: {
        required,
        alphaNum
      }
    }
  };
  
  </code></pre>
  
  <p>Here comes my question, how can I make <code>myInputValue</code> to accept an additional character dot(.)?</p>
  
  <p>Which will total accept these things</p>
  
  <ol>
  <li><code>abcdefghijklmnopqrstuvwxyz</code></li>
  <li><code>ABCDEFGHIJKLMNOPQRSTUVWXYZ</code></li>
  <li><code>0123456789</code></li>
  <li><code>.</code></li>
  </ol>
  
  <p>How can I achieve this?</p>
