How to use not_to_be_checked method in Playwright Python

There is no outer_html out of the box. But it's not hard to implement it:

locator.evaluate("el => el.outerHTML") 

I would do this:

1. Register a listener with expose_function.
2. Use evaluate to register a listener to newPosts. A Listener on the browser side.
3. Inside that listener call the function you exposed on 1.

Chromium will not allow you to override the Host header. I presume this is because Host is something the browser manages internally. Source.

Why do you want to modify this header?

I guess you are using codegen probably.

That page is a little bit strange for urls as I can see.

Anyways, I fixed your code:

from playwright.sync_api import Playwright, sync_playwright, expect


def run(playwright: Playwright) -> None:
    browser = playwright.chromium.launch(headless=False)
    context = browser.new_context()

    # Open new page
    page = context.new_page()

    # Go to https://www.elections.il.gov/CampaignDisclosure/ContributionSearchByCommittees.aspx?T=637994490317517425
    page.goto(
        "https://www.elections.il.gov/CampaignDisclosure/ContributionSearchByCommittees.aspx")

    # Fill input[name="ctl00\$ContentPlaceHolder1\$txtCmteID"]
    page.locator("input[name=\"ctl00\\$ContentPlaceHolder1\\$txtCmteID\"]").fill("34589")

    page.locator("input:has-text(\"Search\")").click()

    page.locator("text=Download This List").click()

    # Click text=CSV File
    with page.expect_download() as download_info:
        page.locator("text=CSV File").click()
    download = download_info.value
    download.save_as(download.suggested_filename)


    # ---------------------
    context.close()
    browser.close()


with sync_playwright() as playwright:
    run(playwright)

I managed to make a code that closes only a specific tab!

all_pages = page.context.pages
await all_pages[1].close()

After investigating and trying several things, looks like the problem is the user_agent of the browser when is in headless mode, for some reason the default user agent does not like to that page, try with:

def extract_html(self):
    with sync_playwright() as p:
        browser = p.chromium.launch(headless=True)
        page = browser.new_page(user_agent='Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/107.0.0.0 Safari/537.36')
        page.goto('http://book.flygofirst.com/Flight/Select?inl=0&CHD=0&s=True&o1=BOM&d1=BLR&ADT=1&dd1=2022-12-10&gl=0&glo=0&cc=INR&mon=true')
        html = page.inner_html('#sectionBody')
        return html

Until it's actually supported, a workaround is to use scripts in your Pipfile:

[scripts]
hooks = "playwright install"

And run pipenv install && pipenv run hooks.

Example with multiple hooks:

[scripts]
hooks = "bash -c 'pipenv run hook_1 && pipenv run hook_2'"
hook_1 = "some_command"
hook_2 = "another_command"

You can use the select_options for selecting 30.

page.select_option('select#MainContent_ddlRecords', '30')

You can use the text selector and then click the checkboxes like this:

page.locator("text=Tabloul avocaţilor stagiari").click()

Your locator should look like this. Replace ":" with ">>"

div[class="some-class"]>>nth=3
