An alert dialog is often used if you want to make sure information comes through to the user.
When an alert dialog pops up, the user will have to click "OK" to proceed.
All of AlertifyJS animation/transition effects are disabled due to user preference that the system minimizes the amount of animation or motion it uses. See prefers-reduced-motionCSS media feature.
onok
{ Function }
Description: Gets or sets a callback function to be invoked when the user clicks 'Ok' button or closes the dialog.
Default:undefined
alertify.alert('a callback will be invoked on ok.').set('onok', function(closeEvent){ alertify.success('Ok');} );
