Dynatree展开选定节点的父级

问题描述

我的网页上的Dynatree运行良好.我正在使用initAjax来获取结构.当我生成json时，我会在适当的位置包括 "select":true 来选中复选框.大多数(所有)复选框都位于从根目录开始向下三级的深度.

I have Dynatree running well on my page. I am using an initAjax to get the structure. When I generate my json I include "select": true where appropriate to select check-boxes. Most (all) of the check-boxes are at a depth of three levels down from the root.

我想扩展所选节点的父级，以便用户在页面加载时可以看到所选复选框.

I would like to expand the parents of the selected nodes so the user can see the selected check-boxes when the page loads.

我认为我需要对getPostedNodes的onPostInit函数进行操作，但是我无法确定代码?我不确定是否应该使用each语句遍历所选节点?任何帮助将不胜感激！

I think I need to do something on the onPostInit function with getSelectedNodes, but I can not nail down the code?? I'm not sure if I should be using a each statement to loop through the selected nodes? Any help would be greatly appreciated!

-更新-

我知道了！

onPostInit: function(isReloading, isError) {
            var tree = $('#tree').dynatree('getTree');
            var selKeys = $.map(tree.getSelectedNodes(), function(node){
                node.makeVisible();
            });
         }

推荐答案

响应时间略短:

onPostInit: function() {
    $.map(this.getSelectedNodes(), function(node){
        node.makeVisible();
    });
}
