ZTree节点的常用操作

在以前项目改造过程中涉及到ZTree的简单应用，在接下来的项目中有个业务模块涉及到ZTree节点的操作，包含新增，删除，修改，留代码备忘。

首先是ztree的配置信息

   var setting = {
            data: {
                simpleData: {
                    enable: true
                }
            },
            edit: {
                enable: true,
                showRemoveBtn: false,
                showRenameBtn: false
            }
        };

新增方法

 var newCount = 1;
 function addNode(e) {
            var zTree = $.fn.zTree.getZTreeObj("groupTree");
            if (!zTree) {
                var zNodes = [];
                zTree = $.fn.zTree.init($("#groupTree"), setting, zNodes);
            }
            var isParent = e.data.isParent,
            nodes = zTree.getSelectedNodes(),
            treeNode = nodes[0];
            if (treeNode) {
                treeNode = zTree.addNodes(treeNode, { id: (100 + newCount), pId: treeNode.id, isParent: isParent, name: "new node" + (newCount++) });
            } else {
                treeNode = zTree.addNodes(null, { id: (100 + newCount), pId: 0, isParent: isParent, name: "new node" + (newCount++) });
            }
        
        };

删除方法

 function removeNode(e) {
            var zTree = $.fn.zTree.getZTreeObj("groupTree"),
            nodes = zTree.getSelectedNodes(),
            treeNode = nodes[0];
            if (nodes.length == 0) {
                alert("请先选择一个节点");
                return;
            }
            zTree.removeNode(treeNode, false);
        };

修改方法

 function UpdateNode(stext) {
            var zTree = $.fn.zTree.getZTreeObj("groupTree"),
            nodes = zTree.getSelectedNodes(),
            treeNode = nodes[0];
            if (nodes.length == 0) {
                alert("请先选择一个节点");
                return;
            } else {
                treeNode.id = stext;
                treeNode.name = stext;
                zTree.updateNode(treeNode, false);
            }
        }

页面加载完成绑定事件

  window.onload = function () { 
            $("#addParent").bind("click", { isParent: true }, addNode);
            $("#addLeaf").bind("click", { isParent: false }, addNode);
            $("#removeNode").bind("click", removeNode);
        }
