1. Contexte du problème
(1) Générer zTree
(2) Cliquez sur le nœud pour sélectionner et attribuer une valeur dans la zone de saisie
(3) Entrez un certain caractère, le nœud de l'arborescence contenant le caractère est sélectionné et la couleur change
2. Code source d'implémentation

3. Résultat de la mise en œuvre
(1) Lors de l'initialisation
( 2) Cliquez sur le nœud
(3) Saisissez un certain caractère
4. Analyse du problème
(1) Défauts
Lorsqu'un caractère est saisi dans la zone de saisie, la couleur du nœud change, mais il ne peut pas être réinitialisé (restaure la couleur d'origine)
