  这是应用的组件

                 <el-tree
                    :data="hovePermissData"
                    :default-checked-                                       keys='checkEditorData'
                    @check-change="treeNodeEditor"
                    :show-checkbox='true'
                    :indent="40"
                    default-expand-all
                    node-key="number"
                    ref="tree"
                    highlight-current
                    :props="defaultPropsEditor">
                 </el-tree>

Answer 1

@node-click=(data,node)=>...，node包含了parent，自己写个while拿所有的parent即可

Answer 2

// 根据子节点id查询所有父节点id
function getParent (array, key) {
  let result = [];
  let toToo = true;
  const catchData = (array, key) => {
    array.forEach( item => {
      if (!toToo) return;
      result.push(String(item['id']));
      if (item['id'] === key) {
        toToo = false;
      } else if (item['children']) {
        catchData(item['children'], key);
      } else {
        result.pop();
      }
    });
    toToo && result.pop();
  };
  catchData(array, key);
  return result;
}
