Why cant I type any text in the textbox?

Jan 24, 2013 12:21 PM|LINK
Hi,

I am using the following javascript function which detects whether ctrl + any of the arrows keys has been pressed.
This works, however I am facing a problem where by I can't actually type in any text in the textbox.

Does anyone know why this might be and what I can do to over come this?
Is it because this function is called on every keydown press?

Any help would be much appreciated as I have been struggling with this for a long time.

Thank you very much
```
function keydownpress(data, event) {
    event = event || window.event;
    var keyCode = event.keyCode || event.which,
        arrow = { left: 37, up: 38, right: 39, down: 40 };

    if (event.ctrlKey) {
        switch (keyCode) {
        case arrow.left:
            alert('ctrl + left');
            break;
        case arrow.right:
            alert('ctrl + right');
            break;
        case arrow.up:
            alert('ctrl + up');
            break;
        case arrow.down:
            alert('ctrl + down');
            break;
        }
    }
}
```

Hi,

alert() method blurs the focus off the textbox,

try console.log() instead of alert()

and check the results in console.

Happy Coding ! Mark as Answer if it helps.

Hi,

Thank you for your reply, even without the alerts, I still cannot type any actual text in the textbox which calls this function with the onkeydown event.

Please can you offer advise on how I can fix this issue?

Thank you

I don't see anything in the code that would prevent the typing. Are you sure the text box doesn't have the attribute ReadOnly = true?

thanks for your reply.

my textbox is knockout js bound and by default when it uses an event property it prevents default behaviour.

i managed to fix my code by returning true after the event, which allowed me to type text in.
