点击复选框或者 单选框后添加节点

var treeObj = $.fn.zTree.getZTreeObj("tree");  
var selectedNode = treeObj.getCheckedNodes();  // getSelectedNodes
var newNode = { name: $("#newName").val() };  
if (selectedNode.length > 0) {
    newNode = treeObj.addNodes(selectedNode[0], newNode);  
} 

如果没有选择节点，则在目录根节点添加 新节点：

var treeObj = $.fn.zTree.getZTreeObj("tree");  
var selectedNode = treeObj.getCheckedNodes();  // getSelectedNodes
var newNode = { name: $("#newName").val() };  

if(!selectedNode.length){
newNode = treeObj.addNodes(treeObj.getNodes(), newNode);  
creatTree();
}else{

 if (selectedNode.length > 0) {
     newNode = treeObj.addNodes(selectedNode[0], newNode);  
 } 
}

点击复选框或者 单选框后删除节点

var newNode;
    var treeObj = $.fn.zTree.getZTreeObj("tree");
    nodes = treeObj.getCheckedNodes(true)

    $(nodes).each(function(i,v){
    newNode = treeObj.removeNode(nodes[i]);  
    })

或者

function clickFun(ev, treeId, treeNode) {
        deleteChildren = treeNode.children; 

  $(deleteChildren).each(function(i,v){
          var treeObj = $.fn.zTree.getZTreeObj("tree");   
          var selectedNode = treeObj.getCheckedNodes();   // getSelectedNodes
          var newNode; 
              if (selectedNode.length > 0) {
                  newNode = treeObj.removeNode(deleteChildren[i]);  
              } 
  })
  }
