jQuery使用zTree插件实现可拖拽的树示例

 <ul id="modelTree" class="ztree"></ul> 

 var setting = {
 data: {
  key:{
   name:'nodeName'
  },
  simpleData: {
   enable: true,
   idKey: 'nodeId',
   pIdKey: 'parentNodeId'
  },
  keep:{
   leaf:true,
   parent:true,
  }
 },
 edit:{
  drag:{
   isCopy: false,
   isMove: true,
   prev: true,
   next: true,
   inner: true,
   autoOpenTime: 0,
   minMoveSize: 10


  },
  enable:true,
  editNameSelectAll: true,
  removeTitle: "删除节点",
  renameTitle: "编辑节点名称",
  showRemoveBtn: false,
  showRenameBtn: false,
 },

 callback: {
  beforeClick: beforeClick,

  beforeDrag:beforeDrag,
  beforeDragOpen:beforeDragOpen,
  beforeDrop:beforeDrop,
  onDrag:onDr},
}; 

 //拖拽之前调用的函数
function beforeDrag(treeId,treeNode){
 if(treeNode[0].nodeType == 'GROUP'){
  return false;
 }

  return true;
 }
 var node = treeNode[0].getParentNode();
 var modelType = treeNode[0].getParentNode().modelType;
 if(modelType == 'INTERFACE'){
  return false;
 }else {
  return true;
 }
}

//预留被拖拽的回调函数
function onDrag(event, treeId, treeNode){
 //暂时没用到
}

//拖拽移动到展开父节点之前调用的函数
function beforeDragOpen(){
 return true;
}

//拖拽操作结束之前调用的函数
function beforeDrop(treeId, treeNode, targetNode, moveType){
 BRS.fileLoading('show');
 var result = false;
 if(targetNode == null || (moveType != "inner" && !targetNode.parentTId)){
  BRS.fileLoading('hide');
  return false;
 }
 if(targetNode.modelType != null){
  if((targetNode.modelType == 'INTERFACE' && moveType == 'inner') || targetNode.getParentNode().modelType == 'INTERFACE'){
   BRS.fileLoading('hide');
   return false;
  }
 }
 var objDetail = {
  url: '/api/model/' + treeNode[0].id,
  async:false,
 }

  data.id = treeNode[0].id;
  if(moveType != 'inner'){
   data.groupId = targetNode.parentId;
  }else{
   data.groupId = targetNode.id;
  }
  var obj = {
   type:"put",
   showSuccessMsg: false,
   param: {
    params:JSON.stringify(data)
   },
   async:false,
   url: '/api/model',
  }
  jsonAjax(obj,function(updateData){
   if(updateData != null){
    result = true;
  ing('hide');
 return result;
}

//预留拖拽结束的回调函数
function onDrop(event, treeId, treeNode, targetNode, moveType){
 befod('hide');
 return result;
}

//预留拖拽结束的回调函数
function onDrop(event, treeId, treeNode, targetNode, moveType){
 beforeClick(treeId, treeNode[0]);
} 

// 初始化对象分组树
 var treeObj = $("#modelTree");
 $.fn.zTree.init(treeObj, setting, data);
 zTree_Menu = $.fn.zTree.getZTreeObj("modelTree");
