HTML Form Validation scenarios to Trigger on Safari Mobile - Custom Validation Function optimization guide
I've searched everywhere and can't find a clear answer. I'm working on a personal project and I am experiencing an scenario with form validation not triggering correctly on Safari Mobile. I have a custom validation function that I expect to run on the `submit` event of my form, but it seems that Safari is ignoring this function altogether. Here’s a snippet of my code: ```html <form id="myForm"> <input type="text" id="username" required /> <button type="submit">Submit</button> </form> <script> document.getElementById('myForm').addEventListener('submit', function(event) { const username = document.getElementById('username').value; if (username.length < 3) { alert('Username must be at least 3 characters long.'); event.preventDefault(); } }); </script> ``` When I try submitting the form on Safari Mobile, it just submits without any alert or prevention, whereas it works perfectly on Chrome and Firefox. I’ve tried wrapping my validation logic in a `setTimeout` to ensure it runs after Safari processes the standard validation, but that did not resolve the scenario. I also verified that the `required` attribute is functioning as expected, so the scenario seems to lie specifically with my custom validation logic. Safari version is 14.0.3 on iOS 14.4. I’d appreciate any advice on how to ensure that my custom validation executes properly on this platform, or if there are known quirks with form submissions in Safari Mobile that I need to be aware of. I'd really appreciate any guidance on this. For context: I'm using Html on Ubuntu. Any ideas what could be causing this?
