事件

EventHandler
circle-animation-startfunction(event):
- event - jQuery event
circle-animation-progressfunction(event, animationProgress, stepValue):
- event - jQuery event
- animationProgress - from 0.0 to 1.0
- stepValue - current step value: from 0.0 to value
circle-animation-endfunction(event):
- event - jQuery event

其他:

You can get the <canvas> (but only if the widget is already inited):

$('#circle').circleProgress({ value: 0.5 });
var canvas = $('#circle').circleProgress('widget');

You can get the CircleProgress instance:

var instance = $('#circle').data('circle-progress');

You can redraw existing circle (but only if the widget is already inited):

$('#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

You can change the default options:

$.circleProgress.defaults.size = 50;
