異步配置項

異步加載完成后展開第一項

function zTreeOnAsyncSuccess(event, treeId, treeNode, msg) {
   zTree = $.fn.zTree.getZTreeObj("treeOrg");
    expand()
};
function expand() {
    var nodes = zTree.getNodes();
    // console.log(nodes)
    if (nodes[0].children[0]) {
        zTree.selectNode(nodes[0].children[0]);
    } else {
        zTree.selectNode(nodes[0])
    }
    setting1.callback.onClick = zTreeOnClickOrg;
    // console.log(nodes)
    if (nodes.length > 0) {
        // console.log(nodes)
        zTree.expandNode(nodes[0], true, false);
    }
}
