ztree 拖拽

一定要引入jquery.ztree.exedit.js文件，不然根本不会触发onDrag事件！！！！！
其他的官网上有例子就不说了

将节点拖拽到handsontable表中

var setting = {             
 data: {                  
  simpleData: {                   
   enable: true,                  
  },                 
  view: {               
   showLine: true           
  },                
},
edit: {
 enable: true,
 showRemoveBtn: false,                  
 showRenameBtn: false,                  
 drag:{                     
  isCopy: false,                        
  prev: false,                  
  next: false,                  
  inner: false              
 }          
},          
callback: {                 
 //拖拽时鼠标放开事件                
 onDrop: treeOnDrop,
 }
};
function treeOnDrop(event, treeId, node, targetNode, moveType) {          
 var dragObj = {};        
 var $destination = $(document.elementFromPoint(event.clientX, event.clientY));      
 var $tr = $destination.closest('tr');        
 var $tbody = $tr.closest('tbody');       
 var col = $tr.children().index($destination);        
 var row = $tbody.children().index($tr);
 //dragObj.row = row;         
 //dragObj.col = col - 1;   
....        
}  

//或者
function treeOnDrop2(event, treeId, node, targetNode, moveType) {         
 var dragObj = {};        
 var row = event.target.cellIndex -1;
 var col =   event.target.parentNode.sectionRowIndex;
 //dragObj.row = row;         
 //dragObj.col = col ;  
....        
}
