Table of Contents

HTML:

<div class="progressCircularBarContainer">
<div class="progressCircularBar" id="dirrerentIDForEachCircle" data-percent="75" data-size="300" data-line="30"></div>
<b>Status</b>
</div>

CSS:

.progressCircularBarContainer {text-align:center;display:inline-block;}
.progressCircularBarContainer b {text-align:center;clear:both;display:block;font-size:40px;color:#5c9cec;}
.progressCircularBar {position:relative;margin:10px;display:inline-block;}
.progressCircularBar canvas {display:block;position:absolute;top:0;left:0;}
.progressCircularBar span {color:#555;display:block;text-align:center;font-size:30px;font-weight:100;margin-left:5px;}

JavaScript:

progressCircularBar('dirrerentIDForEachCircle','#5c9cec');

function progressCircularBar(incomingID, incomingColor){
var el = document.getElementById(incomingID);
var options = {
percent: el.getAttribute('data-percent') || 25,
size: el.getAttribute('data-size') || 220,
lineWidth: el.getAttribute('data-line') || 15,
rotate: el.getAttribute('data-rotate') || 0
}

var canvas = document.createElement('canvas');
var span = document.createElement('span');
span.textContent = options.percent + '%';

if (typeof(G_vmlCanvasManager) !== 'undefined') {
G_vmlCanvasManager.initElement(canvas);
}

var ctx = canvas.getContext('2d');
canvas.width = canvas.height = options.size;

el.appendChild(span);
el.appendChild(canvas);

ctx.translate(options.size / 2, options.size / 2); // change center
ctx.rotate((-1 / 2 + options.rotate / 180) * Math.PI); // rotate -90 deg

//imd = ctx.getImageData(0, 0, 240, 240);
var radius = (options.size - options.lineWidth) / 2;

var drawCircle = function(color, lineWidth, percent) {
percent = Math.min(Math.max(0, percent || 1), 1);
ctx.beginPath();
ctx.arc(0, 0, radius, 0, Math.PI * 2 * percent, false);
ctx.strokeStyle = color;
ctx.lineCap = 'round'; // butt, round or square
ctx.lineWidth = lineWidth
ctx.stroke();
};

drawCircle('#efefef', options.lineWidth, 100 / 100);
drawCircle(incomingColor, options.lineWidth, options.percent / 100);

document.getElementById(incomingID).style.width = options.size+"px";
document.getElementById(incomingID).style.height = options.size+"px";
span.style.width = options.size+"px";
span.style.lineHeight = options.size+"px";
}

Customization:

You can customize it easily as we stated earlier. You can control the below things in the upper code.

  • id="dirrerentIDForEachCircle" Use a unique ID in each of your progress circular bar if you are using many bars at a single web page.
  • data-percent="75" Change the value of the progress circular bar.
  • data-size="300" Change the diameter of the progress circular bar.
  • data-line="30" Change the width of the circle in progress circular bar
  • progressCircularBar('dirrerentIDForEachCircle','#5c9cec'); Call this function with required parameters every time when you need to display progress circular bar.

That’s all you have to change. Rest you can change anything if you are pro in coding. Else do not change anything else.
