CharacterData abstract interface represents a 节点 object that contains characters. This is an abstract interface, meaning there aren't any object of type CharacterData : it is implemented by other interfaces, like 文本 , 注释 ，或 ProcessingInstruction which aren't abstract.

特性

继承的特性来自其父级， 节点 ，和实现 ChildNode and NonDocumentTypeChildNode 接口。

CharacterData.data
是 DOMString representing the textual data contained in this object.
CharacterData.length 只读
返回 unsigned long representing the size of the string contained in CharacterData.data .
NonDocumentTypeChildNode.nextElementSibling 只读
返回 元素 immediately following the specified one in its parent's children list, or null if the specified element is the last one in the list.
NonDocumentTypeChildNode.previousElementSibling 只读
返回 元素 immediately prior to the specified one in its parent's children list, or null if the specified element is the first one in the list.

方法

继承方法来自其父级 节点 ，和实现 ChildNode and NonDocumentTypeChildNode 接口。

CharacterData.appendData()
Appends the given DOMString 到 CharacterData.data string; when this method returns, data contains the concatenated DOMString .
CharacterData.deleteData()
Removes the specified amount of characters, starting at the specified offset, from the CharacterData.data string; when this method returns, data contains the shortened DOMString .
CharacterData.insertData()
Inserts the specified characters, at the specified offset, in the CharacterData.data string; when this method returns, data contains the modified DOMString .
ChildNode.remove()

从其父级的子级列表中移除对象。

CharacterData.replaceData()
Replaces the specified amount of characters, starting at the specified offset, with the specified DOMString ; when this method returns, data contains the modified DOMString .
CharacterData.substringData()
返回 DOMString containing the part of CharacterData.data of the specified length and starting at the specified offset.
