public interface Text
extends CharacterData
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
text.

public Text splitText(int offset) throws DOMException
Breaks this node into two nodes at the specifiedoffset
, keeping both in the tree as siblings. After being split, this node will contain all the content up to theoffset
point. A new node of the same type, which contains all the content at and after theoffset
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 theoffset
is equal to the length of this node, the new node has no data.
- Parameters:
offset
- The 16-bit unit offset at which to split, starting from0
.
- Returns:
- The new node, of the same type as this node.
- Throws:
DOMException
- INDEX_SIZE_ERR: Raised if the specified offset is negative or greater than the number of 16-bit units indata
.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
