jQuery Plugin to draw animated circular progress bars like this:
Check out more examples! Or maybe the crazy one?
Download latest GitHub release
or bower install jquery-circle-progress
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<script src="jquery-circle-progress/dist/circle-progress.js"></script>
<div id="circle"></div>
<script>
$('#circle').circleProgress({
value: 0.75,
size: 80,
fill: {
gradient: ["red", "orange"]
}
});
</script>
You should specify options like in usage example above.
| Option | Description |
| ---- | ---- | ---- |
| value | This is the only required option. It should be from 0.0
to 1.0
Default: 0
|
| size | Size of the circle / canvas in pixels
Default: 100
|
| startAngle | Initial angle (for 0
value)
Default: -Math.PI
|
| reverse | Reverse animation and arc draw
Default: false
|
| thickness | Width of the arc. By default it's automatically calculated as 1/14 of size
but you may set your own number
Default: "auto"
|
| lineCap | Arc line cap: "butt"
, "round"
or "square"
- read more
Default: "butt"
| fill | The arc fill config. You may specify next:
- { color: "#ff1e41" }
- { color: 'rgba(255, 255, 255, .3)' }
- { gradient: ["red", "green", "blue"] }
- { gradient: [["red", .2], ["green", .3], ["blue", .8]] }
- { gradient: [ ... ], gradientAngle: Math.PI / 4 }
- { gradient: [ ... ], gradientDirection: [x0, y0, x1, y1] }
- { image: "http://i.imgur.com/pT0i89v.png" }
- { image: imageInstance }
- { color: "lime", image: "http://i.imgur.com/pT0i89v.png" }
Default: { gradient: ["#3aeabb", "#fdd250"] }
|
| emptyFill | Color of the "empty" arc. Only a color fill supported by now
Default: "rgba(0, 0, 0, .1)"
|
| animation | Animation config. See jQuery animations.
You may also set it to false
Default: { duration: 1200, easing: "circleProgressEase" }
"circleProgressEase"
is just a ease-in-out-cubic easing |
| animationStartValue | Default animation starts at 0.0
and ends at specified value
. Let's call this direct animation. If you want to make reversed animation then you should set animationStartValue
to 1.0
. Also you may specify any other value from 0.0
to 1.0
Default: 0.0
From version 1.1.3
you can specify any config option as HTML data-
attribute.
It will work only on init, i.e. after the widget is inited you may update its properties only via .circleProgress({/*...*/})
method. data-
attributes will be ignored.
Also, object options like "fill"
or "animation"
should be valid JSON (and don't forget about HTML-escaping):
<div
class="circle"
data-value="0.9"
data-size="60"
data-thickness="20"
data-animation-start-value="1.0"
data-fill="{
"color": "rgba(0, 0, 0, .3)",
"image": "http://i.imgur.com/pT0i89v.png"
}"
data-reverse="true"
></div>
When animation is enabled, there are 3 events available:
Event | Handler |
---|---|
circle-animation-start |
function(event) : - event - jQuery event |
circle-animation-progress |
function(event, animationProgress, stepValue) : - event - jQuery event - animationProgress - from 0.0 to 1.0 - stepValue - current step value: from 0.0 to value |
circle-animation-end |
function(event) : - event - jQuery event |
It uses <canvas>
which is supported by all modern browsers (including mobile browsers)
and Internet Explorer 9+ (Can I Use).
I have not implemented any fallback / polyfill for unsupported browsers yet (i.e. for Internet Explorer 8 and older / misc browsers).
Get it:
$('.circle').circleProgress({ value: 0.5 });
var value = $('.circle').circleProgress('value'); // 0.5
It will return the first item's value (by first I mean when $('.circle').length >= 1
).
It works only if the widget is already inited. Raises an error otherwise.
Set it:
$('.circle').circleProgress('value', 0.75); // set value to 0.75 & animate the change
It will update all selected items value and animate the change. It doesn't redraw the widget - it updates the value & animates the changes. For example, it may be an AJAX loading indicator, which shows the loading progress.
$('.circle').circleProgress({ value: 0.5 });
var canvas = $('.circle').circleProgress('widget');
It will return the first item's <canvas>
(by first I mean when $('.circle').length >= 1
).
It works only if the widget is already inited. Raises an error otherwise.
var instance = $('#circle').data('circle-progress');
$('#circle').circleProgress({ value: 0.5, fill: { color: 'orange' }});
$('#circle').circleProgress('redraw'); // use current configuration and redraw
$('#circle').circleProgress(); // alias for 'redraw'
$('#circle').circleProgress({ size: 150 }); // set new size and redraw
It works only if the widget is already inited. Raises an error otherwise.
$.circleProgress.defaults.size = 50;
Here is my proposed solution.
E.g. for Retina support or for responsive design, you can do it in the following way.
There is no full-feature support for IE8 (actually, I didn't imlpement IE8 support at all). But you may follow my recommendations.
Here is what you can do.
It's not in the "core" but you can use my example of mouse/touch events handling.
It's a bit "tricky" but possible. Here is my little collection.
