Html5 Progress Bar Animation

I am using an HTML5 progress bar in my app. I would like to know if there is any way to control the animation speed of the progress bar. I want to show the progress after a certain

Solution 1:

I'm not sure I understand what you mean by "animation" but here is an example of using the progress bar while controlling the speed of progression: http://jsfiddle.net/526hM/

Html:

<progressmax="200"value="1"></progress><divid="val"></div>

Script:

$(document).ready(function(){
    var interval = 2, //How much to increase the progressbar per frame
        updatesPerSecond = 1000/60, //Set the nr of updates per second (fps)
        progress =  $('progress'),
        animator = function(){
            progress.val(progress.val()+interval);
            $('#val').text(progress.val());
            if ( progress.val()+interval < progress.attr('max')){
               setTimeout(animator, updatesPerSecond);
            } else { 
                $('#val').text('Done');
                progress.val(progress.attr('max'));
            }
        }

    setTimeout(animator, updatesPerSecond);
});

Solution 2:

Here is example. JavaScript function:

window.onload = addTenPercent();

functionaddTenPercent() {
    var bar = document.getElementById("progressBar");
    setInterval(addTenPercent, 100);
    bar.value += 5;
};

HTML:

<progress id="progressBar" max="100" value="0"></progress>

Solution 3:

Mantas' answer above looks good and works (without having to use jQuery), but I wonder if we could also use the setTimeout function? Would setTimeout in a recursive function that exits after 100 iterations also work? Copying Mantas' code from above and changing it a little:

JavaScript:

functiononWindowLoad(){ // to be called by onload eventvar bar = document.getElementById("progressBar");
    addOne();
}

functionaddOne() {
    if (bar.value < 100) { // this is the max value of the bar and the # of iterationssetTimeout(addOne, 80); // this literal value controls the speed
        bar.value += 1;    
    }else{  
        return;
    } 
}

HTML:

<progress id="progressBar" max="100" value="0"></progress>
