In diesem Artikel wird die Methode zum „Verschieben eines Knotens zwischen zwei PS mithilfe von ztree“ vorgestellt. Freunde, die sie benötigen, können sich auf
Implementierungsideen beziehen:
Die Knoten in ztree sind Als Datenquelle wird ein JSON-Array verwendet, sodass der JSON-String direkt manipuliert und dann in ein Array von JSON-Objekten konvertiert wird.
2. Initialisieren Sie dann das Ztree-Objekt mit dem neu gebildeten JSON-Array-Objekt neu.
