# Canvas
|
|
|
|
Canvas 是一种特殊的 HTML 元素，默认情况下其内容不会被 rrweb 观测。我们可以通过特定的配置让 rrweb 能够录制并回放 Canvas。
|
|
|
|
录制时包含 Canvas 内的内容：
|
|
|
|
```js
|
|
rrweb.record({
|
|
emit(event) {},
|
|
// 对 canvas 进行录制
|
|
recordCanvas: true,
|
|
});
|
|
```
|
|
|
|
回放时对 Canvas 进行回放：
|
|
|
|
```js
|
|
const replayer = new rrweb.Replayer(events, {
|
|
UNSAFE_replayCanvas: true,
|
|
});
|
|
replayer.play();
|
|
```
|
|
|
|
**回放 Canvas 将会关闭沙盒策略，导致一定风险**。
