树状菜单递归循环遍历获取响应数据,可以顺便重定向

//arr数据大致长这样
arr=[
  {
    a:1,
    childrenn:[
      {
        a:1-1,
        childrenn:[
          {a:1-2,},
          {a:1-2-2,}
        ]
      },
    ]
  },
  {
    a:2,
    childrenn:[
      {
        a:2-1,
      },
    ]
  },
  {
    a:3,
  },
]

//父节点遍历一次 拿chlidren去遍历子节点
arr.forEach(rootNode=>{
  let nodeModels = {
    path: rootNode.uri,
    name: rootNode.text,
    component: rootNode.cls,
    meta: rootNode.iconCls,
    children: [],
    redirect:rootNode.children.length>0?rootNode.children[0].uri:''
  };
  nodeModels.children.push(getChinld(rootNode.children));
  menuArr.push(nodeModels);
});
// 遍历子级节点
function getChinld(childNode) {
  let childArray = [];
  for(var i=0;i<childNode.length;i++){
    let nodeModel = {
      path: childNode[i].uri,
      name: childNode[i].text,
      component: childNode[i].cls,
      meta: childNode[i].iconCls,
      children: [],
      redirect:childNode[i].children.length>0?childNode[i].children[0].uri:'',
    };
    nodeModel.children.push(getChinld(childNode[i].children));
    childArray.push(nodeModel);
  }
  return childArray;
}

console.log(menuArr); //获取到遍历的样子啦
console.table(menuArr);
