A confirm dialog is often used if you want the user to verify or accept something.
When a confirm dialog pops up, the user will have to click either "OK" or "Cancel" 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.
onclosing
{Function}
Description: Gets or sets a function to invoke before closing the dialog. A false invocation result will prevent the dialog from closing.
Default:undefined
alertify.confirm('Demo').set({ onclosing:function(){ alertify.message('confirm is about to close.')}});
