1.绑定事件

  1. <button type="button" class="btn btn-danger" @click="doDelete(item._id)">删除</button>

2.添加方法

  1. methods:{
  2.                 doDelete(id){
  3.                     console.log(id)
  4.                     this.movies = this.movies.filter(item=>item._id != id);
  5.                   //更新数据
  6.                     $.ajax({
  7.                         url:"http://localhost:8080/doDelete",
  8.                         method:"post",
  9.                         data:{
  10.                             id
  11.                         }
  12.                     }).then(res=>{
  13.                         console.log(res)
  14.                     })
  16.                 }
  17.             }

3.index.js配置路由

  1. //index.js
  2. router.post("/doDelete",async ctx=>{
  3.     console.log(ctx.request.body);
  4.     var {id} = ctx.request.body;
  5.     await Top250Model.remove({_id:id})
  6. })
