void DOMRange::insertNode ( | DOMNode * newNode )`[pure virtual]`

Inserts a node into the DOMDocument or DOMDocumentFragment at the start of the Range.

If the container is a DOMText node, this will be split at the start of the Range (as if the DOMText node's splitText method was performed at the insertion point) and the insertion will occur between the two resulting DOMText nodes. Adjacent DOMText nodes will not be automatically merged. If the node to be inserted is a DOMDocumentFragment node, the children will be inserted rather than the DOMDocumentFragment node itself.

  newNode | The node to insert at the start of the Range

Exceptions:

  WRONG_DOCUMENT_ERR: Raised if `newNode` and the container of the start of the Range were not created from the same document.
  HIERARCHY_REQUEST_ERR: Raised if the container of the start of the Range is of a type that does not allow children of the type of `newNode` or if `newNode` is an ancestor of the container.
  INVALID_STATE_ERR: Raised if `detach()` has already been invoked on this object.

Parameters:

  refNode | The node to select.

Exceptions:
