Why Doesn\'t `event.preventDefault()` Work in Internet Explorer, and How Can I Fix It?

Event.preventDefault Does Not Work in Internet Explorer

JavaScript code often utilizes the event.preventDefault() method to prevent default browser behavior, such as form submission. While this method functions seamlessly in most browsers, it encounters difficulties in Internet Explorer (IE).

In IE, the event object lacks the preventDefault method, resulting in an error. To overcome this challenge, you can employ the alternative event.returnValue property:

event.returnValue = false;

This will effectively prevent the form from being submitted in IE.

To ensure compatibility across browsers, you can test for the availability of the preventDefault method:

if (event.preventDefault) event.preventDefault();

Alternatively, you can combine both methods to achieve desired behavior in all browsers:

event.preventDefault ? event.preventDefault() : (event.returnValue = false);
