splitText(int offset) Breaks this node into two nodes at the specified offset, keeping both in the tree as siblings. |
public Text splitText(int offset)
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.
DOMException - INDEX_SIZE_ERR: Raised if the specified offset is negative or greater
than the number of 16-bit units in data.
Textinterface inherits fromCharacterDataand represents the textual content (termed character data in XML) of anElementorAttr. If there is no markup inside an element's content, the text is contained in a single object implementing theTextinterface that is the only child of the element. If there is markup, it is parsed into the information items (elements, comments, etc.) andTextnodes that form the list of children of the element. When a document is first made available via the DOM, there is only oneTextnode for each block of text. Users may create adjacentTextnodes 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. Thenormalize()method onNodemerges any such adjacentTextobjects into a single node for each block of text. See also the Document Object Model (DOM) Level 2 Core Specification.
