# Accessibility.snapshot() method
|
|
|
|
Captures the current state of the accessibility tree. The returned object represents the root accessible node of the page.
|
|
|
|
#### Signature:
|
|
|
|
```typescript
|
|
class Accessibility {
|
|
snapshot(options?: SnapshotOptions): Promise<SerializedAXNode | null>;
|
|
}
|
|
```
|
|
|
|
## Parameters
|
|
|
|
| Parameter | Type | Description |
|
|
| --------- | ------------------------------------------------- | ----------------- |
|
|
| options | [SnapshotOptions](./puppeteer.snapshotoptions.md) | <i>(Optional)</i> |
|
|
|
|
**Returns:**
|
|
|
|
Promise<[SerializedAXNode](./puppeteer.serializedaxnode.md) \| null>
|
|
|
|
An AXNode object representing the snapshot.
|
|
|
|
## Remarks
|
|
|
|
**NOTE** The Chromium accessibility tree contains nodes that go unused on most platforms and by most screen readers. Puppeteer will discard them as well for an easier to process tree, unless `interestingOnly` is set to `false`.
|
|
|
|
## Example 1
|
|
|
|
An example of dumping the entire accessibility tree:
|
|
|
|
```ts
|
|
const snapshot = await page.accessibility.snapshot();
|
|
console.log(snapshot);
|
|
```
|
|
|
|
## Example 2
|
|
|
|
An example of logging the focused node's name:
|
|
|
|
```ts
|
|
const snapshot = await page.accessibility.snapshot();
|
|
const node = findFocusedNode(snapshot);
|
|
console.log(node && node.name);
|
|
|
|
function findFocusedNode(node) {
|
|
if (node.focused) return node;
|
|
for (const child of node.children || []) {
|
|
const foundNode = findFocusedNode(child);
|
|
return foundNode;
|
|
}
|
|
return null;
|
|
}
|
|
```
