当分针在112分钟的时钟中击中56分钟时,小时将改变(根据以下代码,56的位置将是第14小时)。我们尝试了许多天的解决方案,并在Stackoverflow社区的Kaiido的帮助下终于取得了突破。它已成为我们月亮时钟系统第一部分的完整解决方案。目前,我们阻止了将数字值组装到模拟Canvas时钟系统中的步骤。这项钟表工作的目的是实现与科学界携手共进的雄心壮志。您在我们的努力下所做的贡献受到高度尊重。var canvas = document.getElementById("canvas");var ctx = canvas.getContext("2d");var radius = canvas.height / 2;ctx.translate(radius, radius);radius = radius * 0.90setInterval(drawClock, 1000);function drawClock() { drawFace(ctx, radius); drawNumbers(ctx, radius); drawTime(ctx, radius);}function drawFace(ctx, radius) { var grad; ctx.beginPath(); ctx.arc(0, 0, radius, 0, 2 * Math.PI); ctx.fillStyle = 'white'; ctx.fill(); grad = ctx.createRadialGradient(0, 0, radius * 0.95, 0, 0, radius * 1.05); grad.addColorStop(0, '#333'); grad.addColorStop(0.5, 'white'); grad.addColorStop(1, '#333'); ctx.strokeStyle = grad; ctx.lineWidth = radius * 0.1; ctx.stroke(); ctx.beginPath(); ctx.arc(0, 0, radius * 0.1, 0, 2 * Math.PI); ctx.fillStyle = '#333'; ctx.fill();}function drawNumbers(ctx, radius) { var ang; var num; ctx.font = radius * 0.08 + "px arial"; ctx.textBaseline = "middle"; ctx.textAlign = "center"; for (num = 1; num < 29; num++) { ang = num * Math.PI / 14; ctx.rotate(ang); ctx.translate(0, -radius * 0.85); ctx.rotate(-ang); ctx.fillText(num.toString(), 0, 0); ctx.rotate(ang); ctx.translate(0, radius * 0.85); ctx.rotate(-ang); }}function drawTime(ctx, radius) { var now = new Date(); var hour = now.getHours(); var minute = now.getMinutes(); var second = now.getSeconds(); //hour hour = hour % 12; hour = (hour * Math.PI / 6) + (minute * Math.PI / (6 * 60)) + (second * Math.PI / (360 * 60)); drawHand(ctx, hour, radius * 0.5, radius * 0.07); //minute minute = (minute * Math.PI / 30) + (second * Math.PI / (30 * 60)); drawHand(ctx, minute, radius * 0.8, radius * 0.07); // second second = (second * Math.PI / 30); drawHand(ctx, second, radius * 0.9, radius * 0.02);}
