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

event.preventDefault() Function Not Functional in IE: A Solution

The JavaScript code provided encounters an issue specifically within Internet Explorer (IE). While the event.preventDefault() method functions effectively in other browsers like Firefox, it elicits an error in IE. This error stems from the absence of the preventDefault method in the event object in IE.

The Fix

To address this disparity, IE uses an alternative approach:

event.returnValue = false;

This method effectively prevents the form from submitting in IE.

Ensuring Compatibility

To ensure compatibility across all browsers, the following code can be employed:

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

Comprehensive Solution

To combine both approaches and ensure seamless functionality in all browsers, the following code can be utilized:

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

By incorporating this solution into the provided JavaScript code, the error in IE will be resolved, and the form submission will be prevented as intended in all browsers.
