Using jQuery would look something like this:

$(function() {
     // Focus on load
     $('.scanner').focus();
     // Force focus
     $('.scanner').focusout(function(){
         $('.scanner').focus();
     });
     // Ajax Stuff
     $('.scanner').change(function() {
         $.ajax({
             async: true,
             cache: false,
             type: 'post',
             url: '/echo/html/',
             data: {
                 html: '
This is your object successfully loaded here.
'
             },
             dataType: 'html',
             beforeSend: function() {
                 window.alert('Scanning code');
             },
             success: function(data) {
                 window.alert('Success');
                 $('.objectWrapper').append(data);
             },
             // Focus
             complete: function() {
                 $('.scanner').val('').focus();
             }
        });
    });
});
