Static methods

Events

  • change:content( eventInfo, range, data = { data.deletionPosition } )

    Fired when LiveRange instance boundaries have not changed after a change in document but the change took place inside the range, effectively changing its content.

    Parameters

    An object containing information about the fired event.

    range : Range

    Range with start and end position equal to start and end position of change range.

    data : Object

    Object with additional information about the change.

    Properties
    data.deletionPosition : null

    Due to the nature of this event, this property is always set to null. It is passed for compatibility with the event-change:range event.

    Fired when LiveRange instance boundaries have changed due to changes in the document.
