Some websites have the annoying quality of auto-refreshing using some JS magic. This seems to bypass the browser’s “do not auto refresh” options.

My question – is there a simple way of telling the browser (also via JS, in an add-on) “do not listen to them! Never auto-refresh!”?

EDIT: Just to make myself clear – I want to write a browser extension that prevents the current page from giving a “refresh” signal – whether auto-refresh or “standard” refresh given automatically by the page using some timer. I think that’s a standard JS question…

    Edit: Sorry, I missunderstood the question!

    I think that what you need is this:

    window.onkeypress = window.onkeyup = window.onkeydown = function( event ) {
    event.preventDefault();
    // or, in this case: 
    //return false;
};

    When the window will receive the events of keypress, keyup e keydown signals that the default behavior MUST be prevented. If you return false, you will stop the event chain, preventing to execute anything too. The two lines have the same effect, give a try commenting each line.

    Here is a improoved example:

    <!DOCTYPE html>
<html>

    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>Testing...</title>
    </head>
    <body>
        <div id="clickDiv">Click me ;)</div>
        <br/>
        <input id="typeInput" value="Type something ! (here)"/>
    </body>

    <script type="text/javascript">
            window.onkeypress = window.onkeyup = window.onkeydown = function( event ) {
                event.preventDefault();
                return false;
            };
            document.getElementById( "clickDiv" ).onclick = function( event ) { 
                 console.log( "you clicked me and the window events related to the keyboard are still being prevented ;)" );
            };
            document.getElementById( "typeInput" ).onkeyup = function( event ) { 
                 console.log( "you typed inside me and the window events related to the keyboard are still being prevented ;)" );
            };
    </script>

</html>
