使用 zTreeObj.reAsyncChildNodes 方法
Function 参数说明
function 举例
- 重新异步加载 zTree
var treeObj = $.fn.zTree.getZTreeObj("tree");
treeObj.reAsyncChildNodes(null, "refresh");
- 重新异步加载当前选中的第一个节点
var treeObj = $.fn.zTree.getZTreeObj("tree");
var nodes = treeObj.getSelectedNodes();
if (nodes.length>0) {
treeObj.reAsyncChildNodes(nodes[0], "refresh");
}
