πŸš€ What is Javascript Alert?

One useful function that's native to JavaScript is the alert() function. This function will display text in a dialog box that pops up on the screen. ... JavaScript functions are called in response to events. When the page loads, or when a user clicks on, hovers over, or tabs to a specific link, these are all events.

πŸš€ Handling Confirm Box in Selenium

A confirm box is often used if you want the user to verify or accept something.

When a confirm box pops up, the user will have to click either "OK" or "Cancel" to proceed.

If the user clicks "OK", the box returns true. If the user clicks "Cancel", the box returns false.

πŸš€ What is Prompt Box and How to handle it in Selenium?

A prompt box is often used if you want the user to input a value before entering a page.

When a prompt box pops up, the user will have to click either "OK" or "Cancel" to proceed after entering an input value.

If the user clicks "OK" the box returns the input value. If the user clicks "Cancel" the box returns null.
