Automatically close jQuery UI Dialog Modal Popup after delay 5 seconds (some seconds)
The following HTML Markup consists of jQuery UI Script and CSS files inherited to use jQuery UI Dialog Modal Popup box, an HTML DIV and a Button.
Inside the jQuery document ready event handler, the Button has been assigned a jQuery click event handler. When the Button is clicked, the jQuery UI Dialog Modal Popup box is initialized.
Inside the Open event handler of the jQuery UI Dialog Modal Popup box, using the JavaScript setTimeout function and the jQuery UI Dialog “close” command, the jQuery UI Dialog Modal Popup box is set to automatically close after delay of 5 seconds (some seconds).
