Different option for key press identification

My JavaScript skills are still at a beginner level and I've come across a bug that's causing me trouble.

The issue is with keyCode not working on mobile devices (Chrome). It seems that mobile devices do not support keyCode.

I think I could use isNaN with an ! instead of the code below, but I'm having trouble writing it in a clear way.

var code = window.event.keyCode; 

if ((code > 34 && code < 41) || (code > 47 && code < 58) || (code > 95 && code < 106) || code == 8 || code == 9 || code == 13 || code == 46){ 
    window.event.returnValue = true; 
    return; 
}

If anyone has any suggestions, I would greatly appreciate it! Feel free to leave your comments on the microsite as well if you'd like.

Sincerely,

Answer №1

Implement jQuery and make use of .which

The .which method helps to normalize keyCode and keyValue across different browsers

let keycode = event.which
if(keycode === 14){
    //perform a specific action
}

Answer №2

Learn about utilizing the power of event.which in jQuery

Understanding that event.which is a way to standardize event.keyCode and event.charCode, making it simpler to handle keyboard input.

$("<input-element-id-or-name>").keyup(function(e){
     if(e.which === 27) {
         // take action
     }
});
