iview表格批量删除

//第一步：在table里面加上on-selection-change
<Table border
       :loading="loading"
       :columns="columns"
       ref="selection"
       :data="table.rows"
       @on-selection-change="changeSelect"
//第二步：在columns加上selection
 columns: [
  {
    type: 'selection',
    width: 60,
    align: 'center'
  },
//多选
changeSelect(e){
  this.ids = [];
  if(e.length > 0){
    this.isSele = false;
    for(let i = 0;i < e.length;i++){
      this.ids.push(e[i].id)
    }
  }else{
    this.isSele = true;
  }
},
delAll(){
  //this.ids = this.ids.join(",");
  this.$Modal.confirm({
    title:'确认删除吗？',
    content:"您确认要删除所选的数据吗?",
    onOk:()=>{
      sendRequest(deleAll,this.ids).then((res)=>{
        if(res){
          this.$Message.success('删除成功');
          this.find();
        }
      })
    }
  })
},
