JavaScript¶

Methods for executing custom JavaScript on the page.

execute_js¶

Executes JavaScript code and returns the result.

result = await browser.execute_js("return document.title")

Examples¶

# Page title
title = await browser.execute_js("return document.title")

# Current URL
url = await browser.execute_js("return window.location.href")

# Scroll to bottom
await browser.execute_js("return window.scrollTo(0, document.body.scrollHeight)")

Limitation

execute_js supports simple expressions with return. For complex logic, use extract_data or manipulate via click/type_into.

inject_js¶

Executes JavaScript without waiting for a return value.

await browser.inject_js("window.scrollTo(0, 0)")

switch_to (iframes)¶

Switches the context into an iframe.

async with browser.switch_to("#iframe-content") as frame:
    await frame.click("#btn-inside-iframe")
    text = await frame.get_text(".result")

Under development

Iframe support is planned for v2. Currently switch_to returns the same context.
