波纹管是使用HTML5

<progress id="progressBar" value="0" max="100" style="width:300px;"></progress> 
<span id="status"></span> 
<h1 id="finalMessage"></h1> 
<script type="text/javascript" language="javascript"> 
function progressBarSim(al) { 
    var bar = document.getElementById('progressBar'); 
    var status = document.getElementById('status'); 
    status.innerHTML = al+"%"; 
    bar.value = al; 
    al++; 
    var sim = setTimeout("progressBarSim("+al+")",300); 
    if(al == 100){ 
    status.innerHTML = "100%"; 
    bar.value = 100; 
    clearTimeout(sim); 
    var finalMessage = document.getElementById('finalMessage'); 
    finalMessage.innerHTML = "Process is complete"; 
} 
    } 
    var amountLoaded = 0; 
    progressBarSim(amountLoaded); 
</script>
