JavaScript alerts are native browser dialogs. Use driver.switchTo().alert() to handle them.

Alert types:

Type	Description
`alert()`	Info message with OK button
`confirm()`	Question with OK and Cancel
`prompt()`	Input request with OK and Cancel

Accept (click OK):

Java

Alert alert = driver.switchTo().alert();
System.out.println("Alert text: " + alert.getText());
alert.accept();

Dismiss (click Cancel):

Java

driver.switchTo().alert().dismiss();

Type into prompt:

Java

Alert prompt = driver.switchTo().alert();
prompt.sendKeys("My input text");
prompt.accept();

Wait for alert before switching:

Java

WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(10));
wait.until(ExpectedConditions.alertIsPresent());
Alert alert = driver.switchTo().alert();
alert.accept();

Common error: NoAlertPresentException — alert has not appeared yet. Always use ExpectedConditions.alertIsPresent() before switching.
