2D-Position

Allows absolutely positioned elements to be moved by dragging.

Command 2D-Position

 

Call execCommand with the following parameters.

    Required. Variant of type Boolean specifying whether the element is to be absolutely positioned.

    Set to false.

  • vValue
    Required. Variant of type Boolean specifying whether this feature is to be on or off.

ms-beginUndoUnit

Starts an undo unit. Any DOM changes between ms-beginUndoUnit and ms-endUndoUnit (including any changes from script) are collected into an undo unit and undone and redone as if they were a single command.

If an undo unit is started through ms-beginUndoUnit and any of the following conditions is met, the current undo unit will be ended automatically:

  • When the user does something that would be an undo-able action, such as typing some text.
  • When the current script completes execution and returns to the event loop.
  • When an undo or redo occurs, either when initiated by the user or by execCommand(“undo”/”redo”).
  • When undo data is cleared by execCommand(“ms-clearUndoStack”).

Undo units cannot be nested. If ms-beginUndoUnit and ms-endUndoUnit are called within another pair of commands, only a single unit will be created to span all editing operations from the first ms-beginUndoUnit to the last ms-endUndoUnit.
