element ui批量删除

批量删除的写法：

1：在el-table 标签中添加一个el-table-column

<el-table-column
 type="selection"
 width="55">
</el-table-column>

2：在el-table 标签中添加一个事件

 @selection-change="handleSelectionChange"

3：通过selection-change 绑定的事件，获取用户选择的多条数据

 handleSelectionChange(val){
      this.multipleSelection = val;
      console.log(this.multipleSelection);
    },

4:获取选数据的id,组成一个数组传到后台

 //确定进去
let selectval = this.multipleSelection;
//循环拿出id
this.ids = []
val.forEach(e =>{this.ids.push(e.id)})
// console.log(this.ids)
let jwt = localStorage.getItem("jwt");
this.$axios.post('api/user/deleteUser',this.ids,{
    headers:{'jwt':jwt}
})
    .then(res =>{

})
