Answer 1

  function recursive(data){

    for (var i = 0,l = data.length; i < l; i++) {

      let item= data[i]

      if(item.intIsDel === 1){

        item['disabled'] = true

        item['strName'] = item['strName'] + ' ' + '(已删除)'

      }

      if(item.listThemeChildren && item.listThemeChildren.length>0){

          recurFn(item.listThemeChildren)

      }

    } 

  }

let arr =[{

  intIsDel:1,

  listThemeChildren:[

    {

      intIsDel:0

    },

    {

      intIsDel:1,

      listThemeChildren:[

        {

          intIsDel:0

        },

        {

          intIsDel:1

        }

      ]

    }

  ]

}];

recursive(arr)
