Mouse

Mouse class

The Mouse class operates in main-frame CSS pixels relative to the top-left corner of the viewport.

Signature:

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

// 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 MouseEvents. 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()` functionality implemented in the platform.

Example 2

For example, if you want to select all content between nodes:

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:

// 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:

await browser
  .defaultBrowserContext()
  .overridePermissions('<your origin>', ['clipboard-read', 'clipboard-write']);
