问题描述
我想像这个解决方案非常简单，如果这是痛苦明显，提前道歉，但我似乎不知道如何设置两个不同的fillStyles两个不同的弧...我只是想绘制不同的颜色圆。下面我将如何通常使用canvas中的其他形状/绘图方法，但由于某种原因使用弧，它将两个弧设置为最后一个fillStyle。
I imagine the solution to this is very simple, and apologize in advance if this is painfully obvious, but I can't seem to figure out how to set two different fillStyles for two different arcs ...I just wanna be able to draw different color circles. Below I have how I would normally do it with other shapes/drawing methods in canvas, but for some reason with arcs it sets both arcs to the last fillStyle.
ctx.fillStyle = "#c82124"; //red
ctx.arc(15,15,15,0,Math.PI*2,true);
ctx.fill();
ctx.fillStyle = "#3370d4"; //blue
ctx.arc(580,15,15,0,Math.PI*2,true);
ctx.fill();
推荐答案
我想你缺少开始和结束路径语句。尝试以下（它适用于我在jsfiddle，）
I think you're missing the begin and end path statements. Try the following (it works for me in jsfiddle, see here)
ctx.fillStyle = "#c82124"; //red
ctx.beginPath();
ctx.arc(15,15,15,0,Math.PI*2,true);
ctx.closePath();
ctx.fill();
ctx.fillStyle = "#3370d4"; //blue
ctx.beginPath();
ctx.arc(580,15,15,0,Math.PI*2,true);
ctx.closePath();
ctx.fill();
