Toolbar options

The toolbar for MediumEditor is implemented as a built-in extension which automatically displays whenever the user selects some text. The toolbar can hold any set of defined built-in buttons, but can also hold any custom buttons passed in as extensions.

Options for the toolbar are passed as an object taht is a member of the outer options object. Example:

var editor = new MediumEditor('.editable', {
    toolbar: {
        /* These are the default options for the toolbar,
           if nothing is passed this is what is used */
        buttons: ['bold', 'italic', 'underline', 'anchor', 'h1', 'h2', 'quote'],
        diffLeft: 0,
        diffTop: -10,
        firstButtonClass: 'medium-editor-button-first',
        headerTags: ['h2', 'h3', 'h4'],
        lastButtonClass: 'medium-editor-button-last',
        standardizeSelectionStart: false,
        static: false,

        /* options which only apply when static is true */
        align: 'center',
        sticky: false,
        updateOnEmptySelection: false
    }
});

• buttons: the set of buttons to display on the toolbar. Default: ['bold', 'italic', 'underline', 'anchor', 'h1', 'h2', 'quote']

• firstButtonClass: CSS class added to the first button in the toolbar. Default: 'medium-editor-button-first'
• headerTags: the types of html elements to create when the H1, H2, or H3 toolbar buttons are clicked. The first element in the array (index 0) indicates which tag name (ie <h3></h3>) will be used when the H1 button is clicked. The second element in the array (index 1) corresponds to the H2 button and the last element (index 2) corresponds to the H3 button. Default: ['h2', 'h3', 'h4']
• lastButtonClass: CSS class added to the last button in the toolbar. Default: 'medium-editor-button-last'
• standardizeSelectionStart: enables/disables standardizing how the beginning of a range is decided between browsers whenever the selected text is analyzed for updating toolbar buttons status. Default: false
• static: enable/disable the toolbar always displaying in the same location relative to the medium-editor element. Default: false

'static' Toolbar Options

These options only apply when the static option is being used

• align: left|center|right - When the static option is true, this aligns the static toolbar relative to the medium-editor element. Default: center
• sticky: When the static option is true, this enables/disables the toolbar "sticking" to the viewport and staying visible on the screen while the page scrolls. Default: false
• updateOnEmptySelection: When the static option is true, this enables/disables updating the state of the toolbar buttons even when the selection is collapsed (there is no selection, just a cursor). Default: false

To disable the toolbar (which also disables the anchor-preview extension), set the value of the toolbar option to false:

var editor = new MediumEditor('.editable', {
    toolbar: false
});

Anchor Preview options

The anchor preview is a built-in extension which automatically displays a 'tooltip' when the user is hovering over a link in the editor. The tooltip will display the href of the link, and when click, will open the anchor editing form in the toolbar.

Options for the anchor preview 'tooltip' are passed as an object that is a member of the outer options object. Example:

var editor = new MediumEditor('.editable', {
    anchorPreview: {
        /* These are the default options for anchor preview,
           if nothing is passed this is what it used */
        hideDelay: 500,
        previewValueSelector: 'a'
    }
}
});

• hideDelay: time in milliseconds to show the anchor tag preview after the mouse has left the anchor tag. Default: 500
• previewValueSelector: the default selector to locate where to put the activeAnchor value in the preview. You should only need to override this if you've modified the way in which the anchor-preview extension renders. Default: 'a'

To disable the anchor preview, set the value of the anchorPreview option to false:

var editor = new MediumEditor('.editable', {
    anchorPreview: false
});

NOTE:

• If the toolbar is disabled (via toolbar: false option or data-disable-toolbar attribute) the anchor-preview is automatically disabled.
• If the anchor editing form is not enabled, clicking on the anchor-preview will not allow the href of the link to be edited

Placeholder Options

The placeholder handler is a built-in extension which displays placeholder text when the editor is empty.

Options for placeholder are passed as an object that is a member of the outer options object. Example:

var editor = new MediumEditor('.editable', {
    placeholder: {
        /* This example includes the default options for placeholder,
           if nothing is passed this is what it used */
        text: 'Type your text'
    }
});

• text: Defines the default placeholder for empty contenteditables when placeholder is not set to false. You can overwrite it by setting a data-placeholder attribute on the editor elements. Default: 'Type your text'

To disable the placeholder, set the value of the placeholder option to false:

var editor = new MediumEditor('.editable', {
    placeholder: false
});

Anchor Form options

The anchor form is a built-in button extension which allows the user to add/edit/remove links from within the editor. When 'anchor' is passed in as a button in the list of buttons, this extension will be enabled and can be triggered by clicking the corresponding button in the toolbar.

Options for the anchor form are passed as an object that is a member of the outer options object. Example:

var editor = new MediumEditor('.editable', {
    toolbar: {
        buttons: ['bold', 'italic', 'underline', 'anchor']
    },
    anchor: {
        /* These are the default options for anchor form,
           if nothing is passed this is what it used */
        customClassOption: null,
        customClassOptionText: 'Button',
        linkValidation: false,
        placeholderText: 'Paste or type a link',
        targetCheckbox: false,
        targetCheckboxText: 'Open in new window'
    }
}
});

• customClassOption: custom class name the user can optionally have added to their created links (ie 'button'). If passed as a non-empty string, a checkbox will be displayed allowing the user to choose whether to have the class added to the created link or not. Default: null
• customClassOptionText: text to be shown in the checkbox when the customClassOption is being used. Default: 'Button'
• linkValidation: enables/disables check for common URL protocols on anchor links. Default: false
• placeholderText: text to be shown as placeholder of the anchor input. Default: 'Paste or type a link'
• targetCheckbox: enables/disables displaying a "Open in new window" checkbox, which when checked changes the target attribute of the created link. Default: false
• targetCheckboxText: text to be shown in the checkbox enabled via the targetCheckbox option. Default: 'Open in new window'
