What is the use of confirm in jquery

The confirm () method is used to display a dialog box with the specified message and OK and cancel button.

The syntax is:

Confirm (message)

Message is used for plain text (instead of HTML text) displayed in a dialog box that pops up on window

If the user clicks the OK button, confirm () returns true. If you click the cancel button, confirm () returns false.

It blocks all input to the browser until the user clicks the OK button or the cancel button to close the dialog box. When confirm () is called, execution of the JavaScript code is paused and the next statement is not executed until the user responds.

The text of the dialog button is immutable, so please write the question or message carefully so that it can be answered with confirmation and cancellation.

Examples are as follows:

Function show_confirm () {var r=confirm ("Press a button!"); if (r==true) {alert ("You pressed OK!");} else {alert ("You pressed Cancel!");}}
