CharacterData: data property
The data
property of the CharacterData
interface represent the value of the current object's data.
Value
A string with the character information contained in the CharacterData
node.
When set to the null
value, that null
value is converted to the empty string (""
), so cd.data = null
is equivalent to cd.data = ""
.
Example
Note: CharacterData
is an abstract interface.
The examples below use two concrete interfaces implementing it, Text
and Comment
.

Setting the content of a text node using data
html

textNode.data = "This text has been set using 'textNode.data'.";
