CharacterData

CharacterData 介面表示了含有字元的 Node 物件。CharacterData 為抽象介面，代表不會有型別為 CharacterData 的物件。物件是由其子介面，如 Text、Comment 或 ProcessingInstruction 等非抽象介面來實作。

屬性

Inherits properties from its parent, Node, and implements the ChildNode and NonDocumentTypeChildNode interface.

CharacterData.data

Is a DOMString representing the textual data contained in this object.

CharacterData.length Read only

Returns an unsigned long representing the size of the string contained in CharacterData.data.

NonDocumentTypeChildNode.nextElementSibling Read only

Returns the Element 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 Read only

Returns the Element 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

Inherits methods from its parent, Node, and implements the ChildNode and NonDocumentTypeChildNode interface.

Appends the given DOMString to the 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()

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()

Returns a DOMString containing the part of CharacterData.data of the specified length and starting at the specified offset.
