jquery zTree 查找所有的叶子节点
jquery zTree 查找所有的叶子节点
// 保存所有叶子节点 10 为初始化大小,并非数组上限 var arrayObj = new Array([10]); /* treeNode: 根节点 result: 用于保存叶子节点的数组 */ // 获取所有叶子节点 function getAllLeafNodes(treeNode, result) { if (treeNode.isParent) { var childrenNodes = treeNode.children; if (childrenNodes) { for (var i = 0; i < childrenNodes.length; i++) { if (!childrenNodes[i].isParent) { arrayObj.push(childrenNodes[i]); } else { arrayObj = getAllLeafNodes(childrenNodes[i], arrayObj); } } } } else { arrayObj.push(treeNode); } return arrayObj; }
常用zTree 操作:
// 获取树节点 var treeObj = $.fn.zTree.getZTreeObj("divTreeContainer"); // 获取树所有的节点 var nodes = treeObj.getNodes(); // 通过 tid 获取节点 var node = treeObj.getNodeByTId(node.tId); // 创建一个节点 var newNode = { id: 1, name:‘wisdo’‘, filePath: ‘http://www.cnblogs.com/wisdo‘}; // 追加节点 treeObj.addNodes(parentNode, newNode)
(function () { var treeIndexZTree = { //树的配置 setting: { data: { key: { //title: "t" }, simpleData: { enable: true } }, callback: { } }, //存放树的节点 zNodes: null, //初始化 init: function (zNodes) { if (!zNodes) { zNodes = treeIndexZTree.getZNoeds(); } treeIndexZTree.zNodes = zNodes; //获取树节点 treeIndexZTree.setting.callback.onClick = treeIndexZTree.onClick; //绑定鼠标左键单击事件 treeIndexZTree.setting.callback.onRightClick = treeIndexZTree.onRightClick; //绑定鼠标右键单击事件 $.fn.zTree.init($("#divTreeContainer"), treeIndexZTree.setting, treeIndexZTree.zNodes); //初始化树 }, //鼠标左键单击事件 onClick: function (event, treeId, treeNode, clickFlag) { if (tagAreaChange) { tagAreaChange(treeNode); } }, //鼠标右键单击事件 onRightClick: function (event, treeId, treeNode) { //$("#divTreeRightMenu").css({ "display": "block", left: event.clientX, top: event.clientY }); }, //获取树节点 getZNoeds: function () { return []; } }; //dom创建完成之后执行 $(function () { //设置标签点树样式 $("#divTreeContainer").css({ "overflow-y": "auto" }); $.ajax({ url: "/Wisdo/Home/GetTree", data: { level: true }, type: "get", async: true, dataType: ‘json‘, success: function (obj) { //debugger; treeIndexZTree.init(obj.data);//ztree初始化 refreshTree(); // 追加子节点,刷新树 }, error: function (XMLHttpRequest, textStatus, errorThrown) { console.log(JSON.stringify(XMLHttpRequest)); console.log(XMLHttpRequest.status); } }); }); })();
