使用HTML5画布绘制贝塞尔曲线

是的，请使用HTML canvasbezierCurveTo()方法在HTML5中绘制Bezier曲线。

示例

您可以尝试运行以下代码以使用画布绘制贝塞尔曲线：

<!DOCTYPE HTML>
<html>
   <head>
      <style>
         #test {
            width: 100px;
            height:100px;
            margin: 0px auto;
         }
      </style>
      <script>
         function drawShape(){

            //使用DOM获取canvas元素
            var canvas = document.getElementById('mycanvas');

            //确保不支持画布时不执行
            if (canvas.getContext){

               //使用getContext使用画布进行绘制
               var ctx = canvas.getContext('2d');
               ctx.beginPath();
               ctx.moveTo(75,40);
               ctx.bezierCurveTo(75,37,70,25,50,25);
               ctx.bezierCurveTo(20,25,20,62.5,20,62.5);
               ctx.bezierCurveTo(20,80,40,102,75,120);
               ctx.bezierCurveTo(110,102,130,80,130,62.5);
               ctx.bezierCurveTo(130,62.5,130,25,100,25);
               ctx.bezierCurveTo(85,25,75,37,75,40);
               ctx.fill();
            } else {
               alert('You need Safari or Firefox 1.5+ to see this demo.');
            }
         }
      </script>
   </head>
   <body id = "test" onload = "drawShape();">
      <canvas id = "mycanvas"></canvas>
   </body>
</html>
