Het CharacterData-interface biedt de gebruikelijke functies van Text- en Comment-knooppunten.
Beschrijving van CharacterData-object
CharacterData is Text en Comment Het hyperinterface van de knoop. Het document bevat nooit CharacterData-knooppunten, ze bevatten alleen Text-knooppunten en Comment-knooppunten. Omdat deze twee knooppunten vergelijkbare functies hebben, zijn deze functies hier gedefinieerd, zodat Text en Comment ervan kunnen afstammen.
Note that it is not necessary to use the string operation methods defined by this interface. The data attribute is a regular JavaScript string, and you can use the + operator to perform string concatenation, and you can use various methods of the String and RegExp objects.
