JavaScript Popup Boxes

 

JavaScript Popup Boxes

 

JavaScript provides various popup boxes to notify, warn, or to get input from

 the user. Popup boxes prevent the user from accessing other aspects of a

 program until the popup is closed, so they should not be overused.

There are three different kinds of popup methods used in JavaScript.

JavaScript Alert Box

An alert dialog box is mostly used to inform or alert the user by displaying

 some messages in a small dialogue box.

JavaScript Confirm Box

A confirmation box is used to let the user make a choice. When JavaScript

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

 proceed to the next step.

Also, based on what the user clicks on we can perform different actions. We

can specify this course of action with conditional logic.

When the user clicks on the OK button then the result variable will

get the value true and if the user clicks on the Cancel button the

result variable will get the value false.

JavaScript Prompt Box

Javascript Prompt Box can be used when we want to get some user input.

When Javascript displays a prompt box, the user will see a popup box with

an input field and buttons "OK" or "Cancel" to proceed after entering an

input value.
