When a prompt dialog pops up, the user will have to click either "OK" or "Cancel" to proceed after entering an input value.
Description: Gets or sets a function to invoke when the dialog has been maximized.
Default:undefined
alertify.prompt('The call back will be invoked once this dialog is fully maximized.')
.set({
onmaximized:function(){
alertify.message('prompt - onmaximized callback.')
},
maximizable:true
});
