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
text.

Append the string to the end of the character data of the node. Upon
success, data
provides access to the concatenation of
data
and the DOMString
specified.
arg | The DOMString to append. |
---|
DOMException | NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly. |
---|
Remove a range of 16-bit units from the node. Upon success,
data
and length
reflect the change.
offset | The offset from which to start removing. |
---|---|
count | The number of 16-bit units to delete. If the sum of
offset and count exceeds
length then all 16-bit units from offset
to the end of the data are deleted. |
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.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly. |
---|
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.
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.
|
The number of 16-bit units that are available through data
and the substringData
method below. This may have the
value zero, i.e., CharacterData
nodes may be empty.
Insert a string at the specified 16-bit unit offset.
offset | The character offset at which to insert. |
---|---|
arg | The DOMString to insert. |
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. |
---|
DOM Level 3 CR
Replace the characters starting at the specified 16-bit unit offset with the specified string.
offset | The offset from which to start replacing. |
---|---|
count | The number of 16-bit units to replace. If the sum of
offset and count exceeds
length , then all 16-bit units to the end of the data
are replaced; (i.e., the effect is the same as a remove
method call with the same range, followed by an append
method invocation). |
arg | The DOMString with which the range must be
replaced. |
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.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly. |

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.
offset | The 16-bit unit offset at which to split, starting from
0 . |
---|
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. |
---|
Extracts a range of data from the node.
offset | Start offset of substring to extract. |
---|---|
count | The number of 16-bit units to extract. |
offset
and
count
exceeds the length
, then all 16-bit
units to the end of the data are returned.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 .
