How to handle new tab using playwright

 

Scenario:

You click a link or button that opens a new tab, and you want to switch to that tab and perform actions.

  const [newPage] = await Promise.all([

    context.waitForEvent('page'),         // Waits for a new tab to be opened

    page.click('a[target="_blank"]'),     // Simulates clicking the link that opens a new tab

  ]);

  // Wait for the new tab to load

  await newPage.waitForLoadState();

  // Do something in the new tab

  console.log('New tab title:', await newPage.title());

  // Example: take screenshot of the new tab

  await newPage.screenshot({ path: 'new-tab.png' });

  await browser.close();

})();

Key Concepts:

• context.waitForEvent('page'): Waits for a new tab or popup.

• The Promise.all() ensures that the event and click happen together.

• newPage.waitForLoadState(): Ensures the new tab is fully loaded before interaction.

XPath Axis Family Tree Analogy

 The major XPath axes follow family tree terminology:

• self:: is you.

Downward:

• child:: are your immediate children.
• descendant:: are your children, and their children, recursively.
• descendant-or-self:: (aka //): are you and your descendants.

Upward:

• parent:: is your mother or father.
• ancestor:: are your parent, and your parent's parent, recursively.
• ancestor-or-self:: are you and your ancestors.

Sideways (consider elements earlier in the document to be younger):

• previous-sibling:: are your younger siblings, in age order.
• following-sibling:: are your older siblings, in age order.
• previous:: are your younger siblings and their descendants, in age order.
• following:: are your older siblings and their descendants, in age order.

---------------------------------------------------------------------------------------------------------------------

• child:: will select the immediate descendants of the context node, but does not go any deeper, like descendant:: does.
• following:: will select all of the nodes that come after the context node and their descendant's, but that does not include the context node's descendants.
• descendant:: will select all of the nodes along the child:: axis, as well as their children, and their children's children, etc..

Sometimes, a picture is worth a thousand words:
