Intercept Ctrl+J in textbox

Hello all,

I'm working with a barcode reader, and after all input, it sends a CR and a CTRL+J, which open the bookmarks window.

Is there anyway of intercepting (and avoiding) this behavior? Reconfigure the barcode for CR only or TAB, unfortunately, is not an option.

Thanks in advance for any help,

Marcelo

Re: Intercept Ctrl+J in textbox

You should be able to handle this using Javascript:

<script type='text/javascript'>
document.getElementById('yourBarcodeInputId').onkeydown = function(e){
    //If CTRL+J is pressed...
    if(e.ctrlKey && e.keyCode == 'J'.charCodeAt(0))
    {
         //Prevent Default (Bookmark Display) from occurring
         e.preventDefault();
         //Handle your CTRL+J functionality here...
    }
}
</script>

Working Demo

PreventDefault should override the original functionality that the browser uses to display the bookmarks and you can then execute your logic following that. You can find an article here with further details on using Javascript to handle these type of events.
