QWebView Disable Backspace Key (But Not on HTML Fields)

[maximo]

In QWebView, pressing the backspace key causes the page to go back. How can I disable that key to have the power to do that functionality, while not disabling the backspace key on HTML fields, and not disabling my ability to do history.back() in a Javascript function (as in when I want a Go Back button)?

Here's the solution. You have to do it in Javascript. Ensure jQuery is loaded in your web pages (even the IFRAME/FRAME ones) and then apply this code:

<script type="text/javascript">
$(document).ready(function(){

    // Disable backspace key except in fields.
    $(document).keydown(function(e) {
        var elid = $(document.activeElement).is('INPUT, TEXTAREA') ;
        if (e.keyCode === 8 && !elid) {
            if(e.ctrlKey) {
                window.history.back();
            } else { // disable backspace
                e.preventDefault();
                return false;
            }
        }
    });

});
</script>
