ztree

获取全部节点数据：

var treeObj = $.fn.zTree.getZTreeObj("tree");

var nodes = treeObj.getNodes();

 

节点拖拽：

callback: {

beforeDrag: beforeDrag,

beforeDrop: beforeDrop

}

 

function beforeDrag(treeId, treeNodes) {

for (var i=0,l=treeNodes.length; i<l; i++) {

if (treeNodes[i].drag === false) {

return false;

}

}

return true;

}

 

function beforeDrop(treeId, treeNodes, targetNode, moveType) {

//扩展 只有一个根节点

var node = targetNode.getParentNode();

if(null!=node){

return targetNode ? targetNode.drop !== false : true;

}else{

return false;

}

//return targetNode ? targetNode.drop !== false : true;

}
