js 获取数据对象后利用map删除部分字段，如去除ID

let bodyData = this.multipleSelection.map(t => {
          delete t.id
           return t
         })h

        let bodyData = JSON.parse(JSON.stringify(this.multipleSelection)) 
        bodyData = bodyData.map(t => {
          delete t.id
          return t
        })

　　还可以这样子
