Question

I have this code: It’s very simple. I create an interval, and that works fine, but when I clear it, that statement is the only thing that fails.

clearinterval(interval);

This line fails, dragging don the whole function with it. If I comment out this one line, discomodeoff() works perfectly, besides that my interval is still running.

var interval;
function discomodeon() {
    interval = setInterval( 'flashtext()', 50 );
    document.body.style.background = "#000000";
    discoball.style.visibility="visible";
    on.style.display="none";
    off.style.display="block";
    music.innerHTML = "<embed src='discomusic.mp3' autostart='true' loop='true' hidden='true'></embed>";
}
function discomodeoff() {
    clearinterval(interval);
    document.body.style.background = "#FFFFFF";
    discoball.style.visibility="hidden";
    on.style.display="block";
    off.style.display="none";
    music.innerHTML = "";
}

I’m not sure why it fails, but it causes discomodeoff() to fail.

It’s clearInterval, not clearinterval.

function discomodeoff() {
    clearInterval(interval);
    document.body.style.background = "#FFFFFF";
    discoball.style.visibility="hidden";
    on.style.display="block";
    off.style.display="none";
    music.innerHTML = "";
}
