import { Mouse } from "https://deno.land/x/frugal@0.9.6/dep/puppeteer/mod.ts";
The Mouse class operates in main-frame CSS pixels relative to the top-left corner of the viewport.
Examples
Example 1
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 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()
functionality implemented in the platform.
For example, if you want to select all content between nodes:
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',
]);
