jQuery使用zTree插件實現(xiàn)可拖拽的樹示例

 <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: "刪除節(jié)點",
 renameTitle: "編輯節(jié)點名稱",
 showRemoveBtn: false,
 showRenameBtn: false,
 },

 callback: {
 beforeClick: beforeClick,

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

 //拖拽之前調(diào)用的函數(shù)

 }else {

 }
}

//預(yù)留被拖拽的回調(diào)函數(shù)
function onDrag(event, treeId, treeNode){
 //暫時沒用到
}

//拖拽移動到展開父節(jié)點之前調(diào)用的函數(shù)

}

//拖拽操作結(jié)束之前調(diào)用的函數(shù)

//預(yù)留拖拽結(jié)束的回調(diào)函數(shù)

// 初始化對象分組樹
