    var width = 100,

            currentFrame = 0,

            canvas = document.getElementById("myCanvas");
            ctx = canvas.getContext("2d");
            image = new Image()
            image.src = 'sprite.png';

    var draw = function(){
            ctx.clearRect(0, 0, width, height);
            ctx.drawImage(image, 0, height * currentFrame, width, height, 0, 0, width, height);

            if (currentFrame == frames) {
              currentFrame = 0;
            } else {
              currentFrame++;
            }
    }

    setInterval(draw, 100);

以上是用于创建在画布中运行精灵动画序列的画布的代码。

现在我想在同一个html中包含另一个画布图像。当我尝试旧的一个被替换，所以请帮我创建另一个带有另一个图像的画布。

任何人都可以通过提供在单个HTML页面中创建多个画布的方法来解决它

Answer 1

在html部分添加：

<canvas id="mySecondCanvas" width="100" height="100">
        <!-- Insert fallback content here -->
        Sorry, your browser still doesn't support canvas technology
    </canvas>

这就是你如何用javascript获取这个画布：

var second_canvas = document.getElementById("mySecondCanvas");
