HTML form "required" attribute on Mobile Safari doesn't work

Mobile Safari on iPad is supposed to be HTML5-compliant, but it seems that the required attribute doesn't work. Anyone know why, or have a decent workaround that doesn't require a ton of JavaScript?

My code

<input type=email class=input placeholder="Email" name="email" required>

This is a jQuery solution to the issue, it highlights the input fields that have failed in a pinky colour too.

$('form').submit(function(){
    var required = $('[required="true"]'); // change to [required] if not using true option as part of the attribute as it is not really needed.
    var error = false;

    for(var i = 0; i <= (required.length - 1);i++)
    {
        if(required[i].value == '') // tests that each required value does not equal blank, you could put in more stringent checks here if you wish.
        {
            required[i].style.backgroundColor = 'rgb(255,155,155)';
            error = true; // if any inputs fail validation then the error variable will be set to true;     
        }
    }
                            
    if(error) // if error is true;
    {
        return false; // stop the form from being submitted.
    }
});

Since iOS 10.3, this attribute is supported.

You can do something before the submit action like this:

<form name="myForm" action="valid.html" onsubmit="checkValid()" method="post">
  ... ...
</form>

After pressing submit button, checkValid() is evoked before it actually submits. a return value of true will continue the submit action.

Refer to this post for further explanation.

If you use PHP, you can add a validation like this 

function validation(){

  if(isset($_POST['submit'])){
  $email = $_POST['email'];

     if(empty($email)){
        echo $error = "Your email cannot be empty";

      } else {
        return true; //or do something next here
     }
   }

You then add this function in php before your form.

It's not supported in iOS yet: when can I use: required.
