Ant-design: Tree选中项

Created on 16 May 2016 · 3Comments · Source: ant-design/ant-design

Tree获取选中项时，能否把选中项的父节点以及父节点的父节点全部获取，比如三级菜单，最后一级叶子节点选中后，获取选中项前面2项获取不到

let sel = [];
function findPath(selected, children, parent = { root: true }) {
  for (var i = 0; i < children.length; i++) {
    const item = children[i];
    if (selected === item.key) {
      sel.push(item);
      return;
    }
    if (item.children) {
      findPath(selected, item.children, item);
      if (sel.length) {
        sel.push(item);
        return;
      }
    }
  }
