複製代碼 代碼如下:
(function ($) {
$nd({
timer: function (action,context,time) {
var _timer;
if ($nction(action)) {
(function () {
_timer = setInterval(function () {
if (!action(context)) {
clearInterval(_timer);
}
}, time);
})();
}
}
});
})(jQuery);
複製代碼 代碼如下:
#wrap
{
display: table;
margin: 0 auto;
}
#cvs
{
display: table-cell;
vertical-align: middle;
}
function drawRound(context) {
if (terclockwise) {
draw(context.x, context.y, context.r, t, t - / 50, terclockwise);
t -= / 50;
return t > 0.5 * ;
}
else {
draw(context.x, context.y, context.r, t, t + / 50, terclockwise);
t += / 50;
return t < ;
}
}
function draw(x, y, r, sAngle, eAngle, counterclockwise) {
var cvs = lementById("cvs");
ctx = ontext("2d");
keStyle = "#f00";
nPath();
(x, y, r, sAngle, eAngle, counterclockwise);
ke();
}
$(function () {
$r(drawRound, { x: 100, y: 100, r: 50, start: 1.5 * , counterclockwise: true }, 200);
$r(drawRound, { x: 100, y: 100, r: 60, start: 0, counterclockwise: false }, 200);
});
