//遞歸過(guò)濾隱藏菜單
const genAuthList=(tree = [], validate = () => {}, param = [], arr = []) =>{
      if (!tree.length) return []
      for (let item of tree) {
        if (!validate.apply(null, [item, ...param])) continue
        let node = { ...item, children: [] }
        arr.push(node)
       if (item.children && item.children.length)
          genAuthList(item.children, validate, param, node.children)
      }
      return arr
    },

tree表示需要過(guò)濾的tree數(shù)組
validate表示需要過(guò)濾的函數(shù),自定義

例子:

genAuthList(router, (it) => !it.hidden)
過(guò)濾tree列表數(shù)據(jù)中包含hidden為true的數(shù)據(jù)(我這邊是做菜單隱藏用的)
