Ein Beispiel dafür, wie jQuery Easyui Treegrid die Funktion zum Anzeigen von Kontrollkästchen implementiert

In diesem Artikel wird die Methode von jQuery Easyui Treegrid zum Anzeigen der Kontrollkästchenfunktion anhand von Beispielcode vorgestellt. Der Code ist einfach und leicht zu verstehen, sehr gut und hat Referenzwert.

Das Folgende wird in diesem Artikel bereitgestellt. Können Sie mir bitte sagen, wie ich das Baumgitter im Bild unten implementieren soll?

Anforderungen: Dynamisches Laden; Kaskadenfreigabetyp, um zu bestimmen, ob die Paketbibliothek/oder der Spiegel angezeigt werden soll (Spalten sind unterschiedlich, Spiegel hat 4 Spalten), prüfen Sie eine Mehrfachauswahl Das Kontrollkästchen wird deaktiviert und die nachfolgenden Kontrollkästchen werden deaktiviert.

Das Folgende ist der spezifische Code:

1. Baumgitter initialisieren (es gibt mehrere Typspalten, bei denen es sich um Feldnamen handelt, die vom Backend-Personal bereitgestellt werden, obwohl ich keine erstellen möchte Reihe von Typen... Khan)

var root = 20543;
   //初始化产品树
   function InitProductTreeGrid(rootid) {
    var type = &#39;<%=Controler.ProductType%>&#39;;
   var ishowPack = true;
   var ishowMirro = true;
   //1,包库；2，镜像
   if (type == &#39;1&#39;) {
    ishowPack = false;
    ishowMirro = true;
   } else {
    ishowPack = true;
    ishowMirro = false;
   };
