Un exemple de la façon dont jQuery Easyui Treegrid implémente la fonction de case à cocher d'affichage

Cet article présente la méthode de jQuery Easyui Treegrid pour afficher la fonction de case à cocher à travers un exemple de code. Le code est simple et facile à comprendre, très bon et a une valeur de référence. Les amis qui en ont besoin peuvent s'y référer

<.>Ce qui suit est fourni dans cet article. Pouvez-vous s'il vous plaît me dire comment implémenter la grille arborescente dans l'image ci-dessous ?

Exigences : chargement dynamique ; vérification en cascade ; type d'autorisation pour déterminer s'il faut afficher la bibliothèque de packages/ou le miroir (les colonnes sont différentes, le miroir a 4 colonnes), cochez une sélection multiple la case, et les cases à cocher suivantes deviennent décochables.

Ce qui suit est le code spécifique :

1. Initialisez la grille arborescente (il existe plusieurs colonnes de type, qui sont des noms de champs fournis par le personnel backend, bien que je ne souhaite pas créer de tas de types... Khan)

var root = 20543;
   //初始化产品树

   var ishowMirro = true;
   //1,包库；2，镜像
   if (type == &#39;1&#39;) {
    ishowPack = false;
    ishowMirro = true;
   } else {
    ishowPack = true;
    ishowMirro = false;
