单行删除与批量删除
一、单行删除
<el-table-column align="center" fixed="right" label="操作" width="100">
<template slot-scope="scope">
<el-button type="text" size="small" icon="el-icon-edit"></el-button>
<el-button
@click="handleClick(scope.row)"
type="text"
size="small"
icon="el-icon-delete"
></el-button>
</template>
</el-table-column>在对应的删除按钮添加事件scope.row保证选中当前行
export default {
data() {
const data = [];
return {
//删除记录的code
deleteCode: []
};
},methods: {
//Table里的点击删除图标\
async handleClick(row) {
const confirmResult = await this.$confirm(
"此操作将永久删除该文件, 是否继续?",
"提示",
{
confirmButtonText: "确定",
cancelButtonText: "取消",
type: "warning"
}
).catch(err => err);
if (confirmResult !== "confirm") {
return this.$message.info("已取消！");
}
this.deleteCode.push(row.id);
//调用的删除接口
const { data: res } = await this.$axios.delete(
"/questionCheck/updateIsDelete/" this.deleteCode,
{
data: this.deleteCode
}
);
if (res.code != "SUCCESS") {
return this.$message.error("删除信息失败！");
}
this.deleteCode = [];
},
}二、批量删除
<el-button @click="batchDeleteBuild(multipleSection)" plain>批量删除</el-button>
export default {
data() {
return {
//被选中的列表记录
multipleSection: [],
};
},methods: {
//批量删除选中数据方法
async batchDeleteBuild() {
//判断是否选择了数据
if (this.multipleSection.length == 0) {
alert("请选择要删除的数据");
return;
}
//如果有选中的数据，那么弹出消息框
const confirmDelete = await this.$confirm(
"此操作会永久删除建筑信息，是否删除？",
"提示",
{
confimrButtonText: "确定",
cancelButtonText: "取消",
type: "warning"
}
).catch(err => err);
//如果用户确认删除，则返回字符串confirm
//如果用户取消删除，则返回字符串cancel
if (confirmDelete !== "confirm") {
return this.$message.info("已取消");
}
//将选中的数据推到deleteCode数组中
for (var i = 0; i < this.multipleSection.length; i ) {
var j = i;
var id = this.multipleSection[j].id;
this.deleteCode.push(id);
}
//删除deleteCode中的数据
const { data: res } = await this.$axios.delete(
"/question/DeleteQuestionBatch",
{
data: this.deleteCode
}
);
if (res.code != "SUCCESS") {
return this.$message.error("删除课程信息失败！");
}
this.deleteCode = [];
},
}简单的批量删除,全选删除

/* 这里的this指向问题需要注意一下每一个用function声明的函数在调用时都会在函数内创建自己的this。
** this一般是函数所操作的对象。如果没有操作的对象。this在"use strict";严格模式下是 undefined，非严格模式下是 window。
** 也就是说，function声明的函数总是有自己的this。从而遮盖外层作用域中的this。
** 如果用es6的箭头函数()=>{}就没有自己的this。在箭头函数()=>{}中访问this，是访问外层作用域中的this
