我无法找到一个很好的适合指令创建从一个JSON结构复选框树视图，所以我这样做了一个自我调用迭代器，因为在这里看到：

I could not find a really good suitable directive for creating a tree view with checkboxes from a JSON-structure, so I did this with a self-calling iterator, as seen here:

现在，我已经得到了唯一的问题是，（看'牛仔'数据线40，有这样的：

Now, the only problem I've got, is that (look at the 'Jeans' data in line 40, there's this:

"chk": true,

这确实当然标志着牛仔裤-checkbox，而不是上面。这些值将来自数据库的正确的（其中甚至以上bransch将有CHK =真实的，但没有少，我在一个如何触发初始泡沫起来，为选中标记所有家长如果一个项目被标记好奇作为真。

This does of course mark the "Jeans"-checkbox, but not the above. These values would come correct from the database (where even the above bransch would have chk = true, but none the less I am curious on how one could trigger the initial "bubble up and mark all the parents as checked" if an item is marked as "true".

有人能帮助我了解如何可以做？

Could someone help me out to understand how that could be done?

非常感谢！

推荐答案

我想preprocess在递归的方式树数据类似于您使用setData功能：

I would preprocess the tree data in a recursive way similar to your setData function:

 function initTree(tree) {
   function processNode(node) {
     angular.forEach(node.children, function(child) {
       if(processNode(child) === true) {
         node.chk = true;   
       }
     });

     return node.chk;
   }

   angular.forEach(tree, processNode);
 };
 initTree($scope.tree);
