How to show error message with checkbox when I submit form

Question

I want to show error message when I click the submit button. So suppose I have 3 checkboxes: (I show one because the other are the same). Please add more code about the form. It is not debuggable at that level. I should have added this as comment, but you can see I don't have enough reputation score.

<label>
     <input type="checkbox"  name="privacy" value="1" id="privacy" required="required" >
      <span class="text-gray" style="font-size: 12px;"> 
        <a href="/privacy-policy/" target="_blank">Privacy</a>
      </span>
</label>

All checkboxes have the attribute required="required" . When I click on the submit button and the checkbox is not selected, I obtain two things:
1) I don't read anything about the "checkbox is empty" that I must read for HTML5 default validation when the attribute is required
2) I obtain this error: An invalid form control with name='privacy' is not focusable.

Anyone can help me?

"I want to show error message when I click the submit button." Show how you did that in your code. "Please add more code about the form" yes, do that. — Mark Schultheiss, Jun 01 '18 at 10:38

Please clean this up as a working example with notes and describe what it is doing for the OP. – Mark Schultheiss Jun 01 '18 at 10:39

Use checked so that it will get checked and check the following code i guess it will help you

$(document).ready(function() {
    $("#submit").click(function() {
    var chkinput = document.getElementById("privacy");
        if (chkinput.checked) {
            alert("Checked!");
        }
        else {
         alert ("Not checked");
        }
    });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
     <input type="checkbox"  name="privacy" value="1" id="privacy" checked>
      <span class="text-gray" style="font-size: 12px;"> 
        <a href="/privacy-policy/" target="_blank">Privacy</a><br/>
        <button id="submit">Submit</button>
      </span>
      </form>

<form method="post">
 <input type="checkbox"  name="privacy" value="1" id="privacy1" required="required">
  <span class="text-gray" style="font-size: 12px;"> 
    <a href="/privacy-policy/" target="_blank">Privacy</a><br/>
    <button>Submit</button>
  </span>
  </form>

Thanks for your code, but it's not correct because I must create a privacy policy field so the user must check the checkbox. I can't show user all checkboxes just selected! — Polly, Jun 01 '18 at 10:35
