One common and basic use of JavaScript is to create a pop-up window. Pop-up windows are a quick and simple way to add interactivity and capture your user's attention. To add a pop-up window to an HTML page, use thescripttags and place your JavaScript code within thescriptelement.You can incorporate three types of pop-up windows in a webpage: an alert box, a confirmation box, and a prompt box. Use an alert box to display a message. This can be useful if you want to grab the user's attention with information about a special promotion. To create an alert box, use the alert() method. Following is an example of an alert box code: alert("Receive a 20% discount today!");?Use a confirmation box to confirm the user's action, such as to accept changes or to proceed to another page. To create a confirmation box, use the confirm() method. Following is an example of a confirmation box code:if (confirm("Do you wish to proceed?")) { alert("You selected OK");}else { alert("You chose to Cancel");}?Use a prompt box to capture information from a user, such as a name, and then perform an action with the information. To create a prompt box, use the prompt() method. Following is an example of a prompt box code: var name = prompt("What is your name?");if (name != null) {alert("Hello " + name);}else {alert("You did not tell me your name. ");}
