js查找tree数据

    // 通过key在树形数据中找到一个数据
    getTreeDataByKey(key, keyName, childrenName, treeData) {
      let result = {}
      function temp(key, keyName, childrenName, treeData) {
        treeData.forEach(item => {
          if (key === item[keyName]) {
            result = item
          }
          if (item[childrenName] != null) {
            temp(key, keyName, childrenName, item[childrenName])
          }
        })
      }
      temp(key, keyName, childrenName, treeData)
      return result
    },

使用

 console.log(this.getTreeDataByKey(data.pid, 'id', 'children', this.dropdown.wpTreeData))
