The character data of the node that implements this interface. The DOM implementation may not put arbitrary limits on the amount of data that may be stored in a CharacterData node. However, implementation limits may mean that the entirety of a node's data may not fit into a single DOMString. In such cases, the user may call substringData to retrieve the data in appropriately sized pieces.
Throws:
  • DOMException – NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly.
  • DOMException – DOMSTRING_SIZE_ERR: Raised when it would return more characters than fit in a DOMString variable on the implementation platform.

Extracts a range of data from the node.
Params:
  • offset – Start offset of substring to extract.
  • count – The number of 16-bit units to extract.
Throws:
  • DOMException – INDEX_SIZE_ERR: Raised if the specified offset is negative or greater than the number of 16-bit units in data, or if the specified count is negative.
    DOMSTRING_SIZE_ERR: Raised if the specified range of text does not fit into a DOMString.
Returns:The specified substring. If the sum of offset and count exceeds the length, then all 16-bit units to the end of the data are returned.
