DOM Object: CharacterData

Properties/Methods

Functional Description
Data
Test Case

data 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 All work and no play makes mozilla a dull lizard.
No it doesn't char001.html

length The number of characters that are available through data and the substringData method below. This may have the value zero, i.e., CharacterData nodes may be empty.
Zero char002.html

substringData()

Parameters
-offset: Start offset of substring to extract.
-count: The number of characters to extract. Extracts a range of data from the node

Return Value
The specified substring. If the sum of offset and count exceeds the length, then all characters to the end of the data are returned.
Many characters. char003.html

appendData()
Parameters
- arg: The DOMString to append. 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. char004.html

insertData()

Parameters
- offset: The character offset at which to insert.
- arg: The DOMString to insert Insert a string at the specified character offset. char005.html

deleteData()

Parameters
- offset: The offset from which to remove characters.
- count: The number of characters to delete. If the sum of offset and count exceeds length then all characters from offset to the end of the data are deleted. Remove a range of characters from the node. Upon success, data and length reflect the change. char006.html

replaceData(offset,count,arg)

Parameters
- offset: The offset from which to start replacing.
- count: The number of characters to replace. If the sum of offset and count exceeds length, then all characters 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. Replace the characters starting at the specified character offset with the specified string. The sum of offset and count does not exceed length.
