HTML <form> submission with custom validation optimization guide in Safari 16
I've spent hours debugging this and I'm integrating two systems and I'm wondering if anyone has experience with I've searched everywhere and can't find a clear answer. I'm working with an scenario where my custom validation for an HTML `<form>` does not work as expected in Safari 16. The form is supposed to validate whether a specific checkbox is checked before allowing submission. In Chrome and Firefox, the validation works flawlessly, but in Safari, it submits the form regardless of the checkbox state. Here is a simplified version of my code: ```html <form id="myForm"> <input type="checkbox" id="accept" /> I accept the terms <button type="submit">Submit</button> </form> <script> document.getElementById('myForm').addEventListener('submit', function(event) { const checkbox = document.getElementById('accept'); if (!checkbox.checked) { event.preventDefault(); alert('You must accept the terms to proceed.'); } }); </script> ``` When I click the submit button without checking the checkbox, I expect to see the alert, but instead, the form submits without any warning in Safari. I tried adding `return false;` after the alert, but that didn’t change anything. I also checked for any conflicting scripts that might be affecting form submission, but everything looks good in the console. Has anyone else faced this scenario? Is there a workaround or specific setting in Safari that I should be aware of to ensure that the custom validation triggers correctly? For reference, this is a production CLI tool. Is this even possible? I recently upgraded to Html 3.10. What's the best practice here? I've been using Html for about a year now. Thanks in advance! Am I approaching this the right way?
