Is it possible to separate the actions called by the cancel button and the onclose for alertify.js

Question

I currently have this:

            $('form#uwbhandler').on('click', function(e){
            e.preventDefault();
            alertify.confirm("Mode 1",
              function(){
                alertify.success('Sent: Success Something');
                socket.emit('send command', {data: 'acommand'});
              },
              function(){
                alertify.success('Sent: Something');
                socket.emit('send command', {data: 'bcommand'});
              }).setHeader('<em>Select Mode</em> ').setting('labels',{'ok':'Mode 1', 'cancel': 'Mode 2'}).set({onshow:null, onclose:function(){ alertify.message('confirm was closed.')}});;
        });

Which is mostly taken from the example on the alertify.js page. However, I want to customize the cancel button action separate from the onclose button. However, closing with the "x" button for the dialog fires the cancel event event after setting a separate onclose function.

I recommend using the Dialog Factory to create your custom dialog.

The confirm dialog definition is set to invoke the cancel action upon closing the dialog.

However, A quick solution would be to inherit from the existing confirm dialog and update its setup to disable invokeOnClose:

alertify.dialog('myCustomDialog', function() {
  return {
    setup: function() {
      return {
        buttons: [{
          text: 'Mode 1',
          key: 13 /*keys.ENTER*/ ,
          className: alertify.defaults.theme.ok,
        }, {
          text: 'Mode 2',
          key: 27 /*keys.ESC*/ ,
          invokeOnClose: false, // <== closing won't invoke this
          className: alertify.defaults.theme.cancel,
        }],
        focus: {
          element: 0,
          select: false
        },
        options: {
          title: '<em>Select Mode</em> ',
          maximizable: false,
          resizable: false
        },
      };
    }
  }
}, false, 'confirm');

Then use a local variable to decide whether to execute the logic inside the onclose callback:

function demo() {
  var modeSelected = false;
  alertify.myCustomDialog("Which mode will it be?",
      function() {
        modeSelected = true;
        alertify.success('Mode 1');
      },
      function() {
        modeSelected = true;
        alertify.success('Mode 2');
      }
    )
    .set({
      onshow: null,
      onclose: function(arg) {
        if (!modeSelected) {
          alertify.message('confirm was closed.');
        }
        modeSelected = false;
      }
    });
}
