Custom Popup

For custom popups you should do the following:

1. Create Popup
2. Show Popup
3. Hide Popup

For a working example please see the Custom Popup Example

Create Popup

First we have to define a template for the custom popup and a list of buttons if necessary. The list of buttons can contain any button already defined in the editor (e.g. bold).

// Define popup template.
Object.assign(FroalaEditor.POPUP_TEMPLATES, {
  'customPlugin.popup': '[_BUTTONS_][_CUSTOM_LAYER_]'
});

// Define popup buttons.
Object.assign(FroalaEditor.DEFAULTS, {
  popupButtons: ['popupClose', '|', 'popupButton1', 'popupButton2'],
});

Secondly we can create the popup.

function initPopup () {
  // Popup buttons.
  var popup_buttons = '';

  // Create the list of buttons.
  if (editor.opts.popupButtons.length > 1) {
    popup_buttons += '<div class="fr-buttons">';
    popup_buttons += editor.button.buildList(editor.opts.popupButtons);
    popup_buttons += '</div>';
  }

  // Load popup template.
  var template = {
    buttons: popup_buttons,
    custom_layer: '<div class="custom-layer">Hello World!</div>'
  };

  // Create popup.
  var $popup = editor.popups.create('customPlugin.popup', template);

  // Assign refresh handler.
  editor.popups.onRefresh('customPlugin.popup', function () {
    console.log ('refresh');
  })

  // Assign hide handler.
  editor.popups.onHide('customPlugin.popup', function () {
    console.log ('hide');
  })

  return $popup;
}

Define the buttons (if they haven't been defined already) from the custom popup.

// Define custom popup close button icon and command.
FroalaEditor.DefineIcon('popupClose', { NAME: 'times' });
FroalaEditor.RegisterCommand('popupClose', {
  title: 'Close',
  undo: false,
  focus: false,
  callback: function () {
    this.customPlugin.hidePopup();
  }
});

// Define custom popup button 1.
FroalaEditor.DefineIcon('popupButton1', { NAME: 'bell-o' });
FroalaEditor.RegisterCommand('popupButton1', {
  title: 'Button 1',
  undo: false,
  focus: false,
  callback: function () {
    alert("popupButton1 was pressed");
  }
});

// Define custom popup button 2.
FroalaEditor.DefineIcon('popupButton2', { NAME: 'bullhorn' });
FroalaEditor.RegisterCommand('popupButton2', {
  title: 'Button 2',
  undo: false,
  focus: false,
  callback: function () {
    alert("popupButton2");
  }
});

Show Popup

The code below can be used to show the custom popup.

function showPopup () {
  // Get the popup object defined above.
  var $popup = editor.popups.get('customPlugin.popup');

  // If popup doesn't exist then create it.
  // To improve performance it is best to create the popup when it is first needed
  // and not when the editor is initialized.
  if (!$popup) $popup = initPopup();

  // Set the editor toolbar as the popup's container.
  editor.popups.setContainer('customPlugin.popup', editor.$tb);

  // If the editor is not displayed when a toolbar button is pressed, then set BODY as the popup's container.
  // editor.popups.setContainer('customPlugin.popup', $('body'));

  // This will trigger the refresh event assigned to the popup.
  // editor.popups.refresh('customPlugin.popup');

  // This custom popup is displayed by pressing a button from the editor's toolbar.
  // Get the button's jQuery object in order to place the popup relative to it.
  var $btn = editor.$tb.find('.fr-command[data-cmd="myButton"]');

  // Set the popup's position.
  var left = $btn.offset().left + $btn.outerWidth() / 2;
  var top = $btn.offset().top + (editor.opts.toolbarBottom ? 10 : $btn.outerHeight() - 10);

  // Show the custom popup.
  // The button's outerHeight is required in case the popup needs to be displayed above it.
  editor.popups.show('customPlugin.popup', left, top, $btn.outerHeight());
}

We must define the editor toolbar button that opens the custom popup:

// Define an icon and command for the button that opens the custom popup.
FroalaEditor.DefineIcon('buttonIcon', { NAME: 'star'})
FroalaEditor.RegisterCommand('myButton', {
  title: 'Show Popup',
  icon: 'buttonIcon',
  undo: false,
  focus: false,
  callback: function () {
    this.customPlugin.showPopup();
  }
});

Hide Popup

The JS code for hiding the custom popup:

function hidePopup () {
  // Hide the custom popup.
  editor.popups.hide('customPlugin.popup');
}

Complete Example

Below is a complete example of how to create a custom popup:

// Define popup template.
Object.assign(FroalaEditor.POPUP_TEMPLATES, {
  'customPlugin.popup': '[_BUTTONS_][_CUSTOM_LAYER_]'
});

// Define popup buttons.
Object.assign(FroalaEditor.DEFAULTS, {
  popupButtons: ['popupClose', '|', 'popupButton1', 'popupButton2'],
});

// The custom popup is defined inside a plugin (new or existing).
FroalaEditor.PLUGINS.customPlugin = function (editor) {
  // Create custom popup.
  function initPopup () {
    // Load popup template.
    var template = FroalaEditor.POPUP_TEMPLATES.customPopup;
    if (typeof template == 'function') template = template.apply(editor);

    // Popup buttons.
    var popup_buttons = '';

    // Create the list of buttons.
    if (editor.opts.popupButtons.length > 1) {
      popup_buttons += '<div class="fr-buttons">';
      popup_buttons += editor.button.buildList(editor.opts.popupButtons);
      popup_buttons += '</div>';
    }

    // Load popup template.
    var template = {
      buttons: popup_buttons,
      custom_layer: '<div class="custom-layer">Hello World!</div>'
    };

    // Create popup.
    var $popup = editor.popups.create('customPlugin.popup', template);

    return $popup;
  }

  // Show the popup
  function showPopup () {
    // Get the popup object defined above.
    var $popup = editor.popups.get('customPlugin.popup');

    // If popup doesn't exist then create it.
    // To improve performance it is best to create the popup when it is first needed
    // and not when the editor is initialized.
    if (!$popup) $popup = initPopup();

    // Set the editor toolbar as the popup's container.
    editor.popups.setContainer('customPlugin.popup', editor.$tb);

    // If the editor is not displayed when a toolbar button is pressed, then set BODY as the popup's container.
    // editor.popups.setContainer('customPlugin.popup', $('body'));

    // Trigger refresh for the popup.
    // editor.popups.refresh('customPlugin.popup');

    // This custom popup is opened by pressing a button from the editor's toolbar.
    // Get the button's object in order to place the popup relative to it.
    var $btn = editor.$tb.find('.fr-command[data-cmd="myButton"]');

    // Compute the popup's position.
    var left = $btn.offset().left + $btn.outerWidth() / 2;
    var top = $btn.offset().top + (editor.opts.toolbarBottom ? 10 : $btn.outerHeight() - 10);

    // Show the custom popup.
    // The button's outerHeight is required in case the popup needs to be displayed above it.
    editor.popups.show('customPlugin.popup', left, top, $btn.outerHeight());
  }

  // Hide the custom popup.
  function hidePopup () {
    editor.popups.hide('customPlugin.popup');
  }

  // Methods visible outside the plugin.
  return {
    showPopup: showPopup,
    hidePopup: hidePopup
  }
}

// Define an icon and command for the button that opens the custom popup.
FroalaEditor.DefineIcon('buttonIcon', { NAME: 'star'})
FroalaEditor.RegisterCommand('myButton', {
  title: 'Show Popup',
  icon: 'buttonIcon',
  undo: false,
  focus: false,
  popup: true,
  // Buttons which are included in the editor toolbar should have the plugin property set.
  plugin: 'customPlugin',
  callback: function () {
    if (!this.popups.isVisible('customPlugin.popup')) {
      this.customPlugin.showPopup();
    }
    else {
      if (this.$el.find('.fr-marker')) {
        this.events.disableBlur();
        this.selection.restore();
      }
      this.popups.hide('customPlugin.popup');
    }
  }
});

// Define custom popup close button icon and command.
FroalaEditor.DefineIcon('popupClose', { NAME: 'times' });
FroalaEditor.RegisterCommand('popupClose', {
  title: 'Close',
  undo: false,
  focus: false,
  callback: function () {
    this.customPlugin.hidePopup();
  }
});

// Define custom popup 1.
FroalaEditor.DefineIcon('popupButton1', { NAME: 'bell-o' });
FroalaEditor.RegisterCommand('popupButton1', {
  title: 'Button 1',
  undo: false,
  focus: false,
  callback: function () {
    alert("popupButton1 was pressed");
  }
});

// Define custom popup 2.
FroalaEditor.DefineIcon('popupButton2', { NAME: 'bullhorn' });
