Bar Code Scanner and Keyboard Issue

Question

Bar Code Scanner and Keyboard. NOTE: My Bar Code Scanner is USB Type.

Then...

What function must be use to trigger the keyboard if i'm at auto.aspx page? I tried this code but no success:

var barcode = document.getElementById('barcodenum');
barcode.addEventListener("keypress", function() { alert("Please use Barcode Scanner!"); document.getElementById('barcodenum').value = "";}, true);

As pointed out by @Robert Skarzycki above, i doubt you can integrate with the scanner using a web page.

On the keypress intercept issue.

Add this to the head section of you page.

  <script type="text/javascript">

        window.onload = function() {              
            var barcode = document.getElementById('barcodenum');
            barcode.addEventListener("keyup", function() {
                alert("Please use Barcode Scanner!");
                document.getElementById('barcodenum').value = "";
            }, true);
        };

    </script>
