# Mouse class
|
|||
|
|
|||
|
The Mouse class operates in main-frame CSS pixels relative to the top-left corner of the viewport.
|
|||
|
|
|||
|
**Signature:**
|
|||
|
|
|||
|
```typescript
|
|||
|
export declare class Mouse
|
|||
|
```
|
|||
|
|
|||
|
## Remarks
|
|||
|
|
|||
|
Every `page` object has its own Mouse, accessible with \[`page.mouse`\](\#pagemouse).
|
|||
|
|
|||
|
The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `Mouse` class.
|
|||
|
|
|||
|
## Example 1
|
|||
|
|
|||
|
```ts
|
|||
|
// Using ‘page.mouse’ to trace a 100x100 square.
|
|||
|
await page.mouse.move(0, 0);
|
|||
|
await page.mouse.down();
|
|||
|
await page.mouse.move(0, 100);
|
|||
|
await page.mouse.move(100, 100);
|
|||
|
await page.mouse.move(100, 0);
|
|||
|
await page.mouse.move(0, 0);
|
|||
|
await page.mouse.up();
|
|||
|
```
|
|||
|
|
|||
|
\*\*Note\*\*: The mouse events trigger synthetic `MouseEvent`s. This means that it does not fully replicate the functionality of what a normal user would be able to do with their mouse.
|
|||
|
|
|||
|
For example, dragging and selecting text is not possible using `page.mouse`. Instead, you can use the [\`DocumentOrShadowRoot.getSelection()\`](https://developer.mozilla.org/en-US/docs/Web/API/DocumentOrShadowRoot/getSelection) functionality implemented in the platform.
|
|||
|
|
|||
|
## Example 2
|
|||
|
|
|||
|
For example, if you want to select all content between nodes:
|
|||
|
|
|||
|
```ts
|
|||
|
await page.evaluate(
|
|||
|
(from, to) => {
|
|||
|
const selection = from.getRootNode().getSelection();
|
|||
|
const range = document.createRange();
|
|||
|
range.setStartBefore(from);
|
|||
|
range.setEndAfter(to);
|
|||
|
selection.removeAllRanges();
|
|||
|
selection.addRange(range);
|
|||
|
},
|
|||
|
fromJSHandle,
|
|||
|
toJSHandle
|
|||
|
);
|
|||
|
```
|
|||
|
|
|||
|
If you then would want to copy-paste your selection, you can use the clipboard api:
|
|||
|
|
|||
|
```ts
|
|||
|
// The clipboard api does not allow you to copy, unless the tab is focused.
|
|||
|
await page.bringToFront();
|
|||
|
await page.evaluate(() => {
|
|||
|
// Copy the selected content to the clipboard
|
|||
|
document.execCommand('copy');
|
|||
|
// Obtain the content of the clipboard as a string
|
|||
|
return navigator.clipboard.readText();
|
|||
|
});
|
|||
|
```
|
|||
|
|
|||
|
\*\*Note\*\*: If you want access to the clipboard API, you have to give it permission to do so:
|
|||
|
|
|||
|
```ts
|
|||
|
await browser
|
|||
|
.defaultBrowserContext()
|
|||
|
.overridePermissions('<your origin>', ['clipboard-read', 'clipboard-write']);
|
|||
|
```
|
|||
|
|
|||
|
