Validating Email Input Using jQuery

I'm struggling to validate the value of an email input using this code. It's not working as expected and I could really use some assistance, please!

HTML

<input type="text" name="email" class="emailInput" /> 
<button class="validateEmail">VALIDATE</button>

JQUERY

$(document).ready(function(){
    var userEmail = $(".emailInput").val();
    var emailValidation = /^[\w\-\.\+]+\@[a-zA-Z0-9\.\-]+\.[a-zA-z0-9]{2,4}$/; 

    $(".validateEmail").click(function(){
        if (emailValidation.test(userEmail)) {
            alert("Email is valid!");
        } else {
            alert("Invalid email address.");
        }
   });
});

If you're looking for a simple way to implement form validation, consider using the jQuery validation library. It provides easy implementation of various validations, such as checking for required fields and valid email formats.

$( "#myform" ).validate({
  rules: {
    field: {
      required: true,
      email: true
    }
  }
});

The value of mailVal will not be the same as setMail. To ensure a match, use: mailVal.test($(".mail").val()) instead of using the == comparison.
