Determining Enter Key Press: .keyCode vs. .which

When detecting keypress events, developers may encounter confusion between using ".keyCode" and ".which" to ascertain if the Enter key was pressed. While some have traditionally relied on ".keyCode," others advocate for the use of ".which."

Cross-Browser Compatibility

The primary distinction lies in cross-browser compatibility. In some browsers, ".keyCode" is employed, while in others ".which" is utilized. To ensure reliability across different browsers, jQuery standardizes the process by using ".which." This simplifies the development process and ensures consistent behavior.

Code Snippet

For those not utilizing jQuery, the following code snippets can be employed to determine the key value regardless of the browser:

var key = 'which' in e ? e.which : e.keyCode;

or

var key = e.which || e.keyCode || 0;

This ensures that even if ".which" is 0, the key value is still obtained.
