The Text interface inherits from CharacterData
and represents the textual content (termed character data in XML) of an
Element or Attr. If there is no markup inside
an element's content, the text is contained in a single object
implementing the Text interface that is the only child of
the element. If there is markup, it is parsed into the information items
(elements, comments, etc.) and Text nodes that form the list
of children of the element.
When a document is first made available via the DOM, there is only one
Text node for each block of text. Users may create adjacent
Text nodes that represent the contents of a given element
without any intervening markup, but should be aware that there is no way
to represent the separations between these nodes in XML or HTML, so they
will not (in general) persist between DOM editing sessions. The
normalize() method on Node merges any such
adjacent Text objects into a single node for each block of
Breaks this node into two nodes at the specified offset,
keeping both in the tree as siblings. After being split, this node
will contain all the content up to the offset point. A
new node of the same type, which contains all the content at and
after the offset point, is returned. If the original
node had a parent node, the new node is inserted as the next sibling
of the original node. When the offset is equal to the
length of this node, the new node has no data.
offsetThe - 16-bit unit offset at which to split, starting from
The new node, of the same type as this node.
DOMException - INDEX_SIZE_ERR: Raised if the specified offset is negative or greater
than the number of 16-bit units in data.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
