handleEdit(index, row) {

   // let id = row._id
    this.$router.push({name: 'news-edit', params : {
      new : row
    }, query: {id: row._id, type: 'edit'}})
  },

让 let id = row._id ,显示id=undefined 但是row._id是有值得 不知道为啥

mounted() {

  debugger
  console.log(this.$route.query.type)
  if ( "edit" == this.$route.query.type ){
    let old = this.$route.params.new
    this.title = old.title
    this.author = old.author
    this.content = old.content
    this.abstract = old.abstract
    this.coverImage = old.coverImage
  }
  console.log(this.title)
},

old也是同样问题 导致下面的title啥的都获取不到
