javascript pop-up boxes complete guide 💯with code examples

 JavaScript pop-up boxes, also known as dialog boxes, are a useful feature for creating interactive and informative user experiences on web pages. There are three types of JavaScript pop-up boxes:

  1. Alert box: Displays an alert message with a single "OK" button.
  2. Confirm box: Displays a message with "OK" and "Cancel" buttons.
  3. Prompt box: Prompts the user to input data and returns the entered value.

Here are some code examples for each of these types of pop-up boxes:

  1. Alert Box:
javascript
alert("This is an alert message!");
  1. Confirm Box:
javascript
var result = confirm("Are you sure you want to delete this item?"); if (result) { // User clicked "OK" deleteItem(); } else { // User clicked "Cancel" or closed the dialog box }
  1. Prompt Box:
javascript
var name = prompt("What is your name?"); if (name != null) { // User clicked "OK" and entered a value greetUser(name); } else { // User clicked "Cancel" or closed the dialog box }

In each example, the function is called with a message to display in the pop-up box. The confirm and prompt boxes also have a return value that can be used to determine the user's choice or input.
