return document.getElementById("progressbar").getAttribute("style","width");
return document.getElementById("progressbar").innerHTML;
}

function setProgress(value) {
document.getElementById("progressbar").setAttribute("aria-valuenow",value);

document.getElementById("progressbar").setAttribute("style","width: " +value+ "%"); 
document.getElementById("progressbar").innerHTML = (value+ "%"); 
}

function increment() {
    var i = getProgress();
    if(i < 18){
        i++;
        setProgress(i); 
    }else{
        alert("Progress Complete!");
    }
}

function decrement() {

    setProgress(d - 1);
}

Answer

Solution:

If there are only 18 questions, at some point, you should be dividing the number of questions answered by 18 and multiplying that value by 100 to get the percentage width youвЂ™re looking for, so something like this:

function getProgress() {
    return document.getElementById("progressbar").getAttribute("aria-valuenow");

    /*return document.getElementById("progressbar").getAttribute("style", "width");
    return document.getElementById("progressbar").innerHTML;*/
}

function setProgress(value) {
    var percent = value / 18 * 100;
    document.getElementById("progressbar").setAttribute("aria-valuenow", value);

    document.getElementById("progressbar").setAttribute("style", "width: " + percent + "%");
    document.getElementById("progressbar").innerHTML = (value);
}

function increment() {
    var i = getProgress();
    if (i < 18) {
        i++;
        setProgress(i);
    }
    
    if (i === 18) {
        alert("Progress Complete!");
    }
}

function decrement() {
    var d = getProgress();
    setProgress(d - 1);
}
