Html5画布在ie8浏览器中不起作用... 你们能告诉我如何修理它吗? 提供我的代码
var animate = function() {
ctx.width = ctx.width;
percent += STEP_PERCENT;
var deg = percent / 100 * deg360;
drawArc('#aaa', radius, deg360);
drawArc('#0e728e', radius, deg);
for (var i = 0, n = Math.floor(deg / deg60); i < n; i++) {
var from = i * deg30 + deg2;
var to = from + deg30 - deg2 * 2
drawArc('#250696', radius, to, from);
}
drawArc('#fff', radius - SPINNER_WIDTH, deg360);
if (percent >= 100) {
document.getElementById('text').innerText = 'FINISHED';
} else {
setTimeout(animate, STEP_DELAY);
}
}

IE8不支持Canvas,有一种叫做excanvas的工作https://code.google.com/p/explorercanvas/
效果相当好,但有些事情仍然不受支持
