HTML form submission triggering unintended behavior in IE 11 with AJAX
I'm working with an scenario where a form submission is causing a full page reload in Internet Explorer 11, even though I'm using AJAX to handle the submission. The form includes a couple of input fields and a submit button, and I’m trying to prevent the default form submission behavior. Here’s the JavaScript code I’m using: ```javascript const form = document.getElementById('myForm'); form.addEventListener('submit', function(event) { event.preventDefault(); // This is supposed to stop the page reload const formData = new FormData(form); fetch('/submit', { method: 'POST', body: formData }) .then(response => response.json()) .then(data => { console.log('Success:', data); }) .catch(behavior => { console.behavior('behavior:', behavior); }); }); ``` Despite the call to `event.preventDefault()`, the form still submits the traditional way. I’ve tested this in Chrome and Firefox, and everything works as expected. The scenario seems to be isolated to Internet Explorer 11. Additionally, I've made sure that the script is running after the DOM is fully loaded. I've also tried using the `onsubmit` attribute directly in the form tag but with similar results. Here’s the HTML part of the form: ```html <form id="myForm" method="POST" action="/submit"> <input type="text" name="username" required /> <input type="password" name="password" required /> <button type="submit">Submit</button> </form> ``` I’m wondering if there are known issues with event handling in IE 11 or if I’m missing something crucial for AJAX form submissions. Any insights or solutions would be greatly appreciated! Am I missing something obvious?
