ztree展开全部节点

$jqueryTree(document).ready(function(){
   queryMenuTree('0');
    //为了避免数据流过大，采用延迟展开
    setTimeout(function(){
        expandAll();
    },1000);
});
var curStatus = 'init', // 当前状态
curAsyncCount = 0,  // 异步加载次数
goAsync = false; //异步

function expandAll(){
    if(!check()){
        return ;
    }
    var treeObj = $jqueryTree.fn.zTree.getZTreeObj("ztree");
    expandNodes(treeObj.getNodes());
    if(!goAsync){
        curStatus = '';
    }
}

function expandAll(){
    if(!check()){
        return ;
    }
    var treeObj = $jqueryTree.fn.zTree.getZTreeObj("ztree");
    expandNodes(treeObj.getNodes());
    if(!goAsync){
        curStatus = '';
    }
}

function expandNodes(nodes){
    //如果nodes为null 则return
    if(!nodes) return;
//将状态设置为expand
    curStatus = 'expand';
    //获取当前的树
    var treeObj = $jqueryTree.fn.zTree.getZTreeObj("ztree");
    //循环展开节点
    for (var i = 0 ; i < nodes.length; i++){
        treeObj.expandNode(nodes[i],true,false,false);
    //递归 如果子节点的是父节点则进行递归操作
        if(nodes[i].isParent && nodes[i].zAsync){
            expandNodes(nodes[i].children);
        } else {
