How to open the new tab using Playwright (ex. click the button to open the new section in a new tab)

Question

I am looking for a simpler solution to a current situation. For example, you open the google (any another website) and you want BY CLICK on the button (ex. Gmail) - open this page in the new tab using Playwright.

let browser, page, context;
describe('Check the main page view', function () {
    before(async () => {
        for (const browserType of ['chromium']) {
            browser = await playwright[browserType].launch({headless: false});
            context = await browser.newContext();
            page = await context.newPage();
            await page.goto(baseUrl);
        }
    });
    after(async function () {
        browser.close();
    });
    
        await page.click(tax);
        const taxPage = await page.getAttribute(taxAccount, 'href');

        const [newPage] = await Promise.all([
        context.waitForEvent('page'),
        page.evaluate((taxPage) => window.open(taxPage, '_blank'), taxPage)]);

        await newPage.waitForLoadState();
        console.log(await newPage.title());

Answer 1

You could pass a modifier to the click function. In macos it would be Meta because you'd open in a new tab with cmd+click. In windows it would be Control.

const browser = await playwright["chromium"].launch({headless : false});
const page = await browser.newPage();
await page.goto('https://www.facebook.com/');
var pagePromise = page.context().waitForEvent('page', p => p.url() =='https://www.messenger.com/');
await page.click('text=Messenger', { modifiers: ['Meta']});
const newPage = await pagePromise;
await newPage.bringToFront();
await browser.close();

it('Open a new tab', async function () {
     await page.click(button, { button: "middle" });
     await page.waitForTimeout(2000); //waitForNavigation and waitForLoadState do not work in this case
     let pages = await context.pages();
     expect(await pages[1].title()).equal('Title');

In my case i am clicking on link in a pop up like (ctrl + click on link) then it opens new tab and work on that new tab

await page.click('#open')
const [newTab] = await Promise.all([
    page.waitForEvent('popup'),
    await page.keyboard.down('Control'),
    await page.frameLocator('//iframe[@title="New tab."]').locator('a').click(), // in popup
    await page.keyboard.up('Control'),
    console.log("clicked on link")
]);
await newTab.waitForFunction(()=>document.title === 'new tab title')
await newTab.fill('#firstname')
await newTab.close() // close the current tab
await page.click('#exitbutton') //back to parent tab and work on it
....
....
await page.close() // close the parent tab

Waiting for new pages is mentioned in the playwright docs now, copied below:

// Start waiting for new page before clicking. Note no await.
const pagePromise = context.waitForEvent('page');
await page.getByText('open new tab').click();
const newPage = await pagePromise;
await newPage.waitForLoadState();
console.log(await newPage.title());

Answer 5

const pages = await this.page.context().pages();
return pages[1]; // Return an opened tab

If you want to switch to the old tab, you don't need to do anything, proceed to work with that old page object. However, if you want to switch to that tab to see what's going on there:

await oldTabPageObject.page.bringToFront();
