HTML Form Submission optimization guide with Custom Input Validation in Chrome 117
I've been researching this but I'm deploying to production and I've looked through the documentation and I'm still confused about I'm having trouble with an HTML form that uses custom validation for a password field. The form should only submit if the password meets certain criteria, but when I try to submit it in Chrome 117, it doesn't trigger the submission at all. I've implemented a custom validation function, but it seems like it’s not getting called. Here’s the relevant code snippet: ```html <form id="myForm" onsubmit="return validateForm()"> <label for="password">Password:</label> <input type="password" id="password" name="password" required> <input type="submit" value="Submit"> </form> ``` And the JavaScript validation function looks like this: ```javascript function validateForm() { const password = document.getElementById('password').value; const minLength = 8; const regex = /[A-Z]/; if (password.length < minLength) { alert(`Password must be at least ${minLength} characters long.`); return false; } if (!regex.test(password)) { alert('Password must contain at least one uppercase letter.'); return false; } return true; } ``` The alerts work as expected, but when the password is valid, I still see no form submission occurring. I checked the console and there's no behavior message, but it seems like the `onsubmit` event is being overridden by Chrome's default behavior. I also tried adding a `preventDefault()` to the `onsubmit` handler to see if that helped, but that just stopped the form from submitting entirely. I’ve tried different browsers, and the form submits correctly in Firefox, but the scenario continues in Chrome. Is there something specific to Chrome 117 that might be causing this question, or could it be a more general scenario with how I’m handling the form submission? Has anyone else encountered this? I'm on Debian using the latest version of Javascript. Am I missing something obvious? This is my first time working with Javascript LTS. For context: I'm using Javascript on Linux. Hoping someone can shed some light on this.
