这里利用Vue进行简单的增删改查操作，可以与后台进行结合，进行增删改查的过程，只需要将接口改一下名字。其中element-ui组件库经常与vue进行结合，使用时需要提前安装好element-ui组件库的环境，这样就没有进行安装演示。

2.代码部分

1. 首先是先将对应的模板<template>写好，包括输入框(查找操作)，增加按钮(增加操作)，删除按钮(删除操作)，修改按钮(修改操作)，表格(显示数据)

<template>
	<div class="back">
		<el-button :span="8" type="primary" @click="adduser" class="add-btn" plain>添加信息</el-button>
		<el-input :span="8" placeholder="请输入内容" v-model="bookname" class="add-btn" clearable>
		</el-input>
		<el-button :span="8" slot="append" icon="el-icon-search" @click="check" class="button"></el-button>
		<el-table :data="bookInfo" style="width: 100%">

			<el-table-column prop="id" label="编号" width="180">
			</el-table-column>
			<el-table-column prop="name" label="书名" width="180">
			</el-table-column>
			<el-table-column prop="writer" label="作者" width="180">
			</el-table-column>
			<el-table-column prop="publish" label="出版社" width="180">
			</el-table-column>

			<el-table-column align="right">
				<!-- <template> -->
					<el-input placeholder="请输入书名搜索" v-model="bookname" clearable>
					</el-input>
					<el-button slot="append" icon="el-icon-search" @click="check" class="button"></el-button>
				<!-- </template> -->
				<template slot-scope="scope">
					<el-button size="mini" @click="edit(scope.row,scope.row.id)">编辑</el-button>
					<el-button size="mini" type="danger" @click.native.prevent="deleteRow(scope.row.id)">删除</el-button>
				</template>

			</el-table-column>
		</el-table>
		<!-- 增加框 -->
		<el-dialog title="增加书籍信息" :visible.sync="dialogVisible1" width="30%" :before-close="handleClose1">
			<div>
				<el-form ref="form" :model="editObj1" label-width="80px">
					<el-form-item label="书名">
						<el-input v-model="editObj1.name"></el-input>
					</el-form-item>
					<el-form-item label="作者">
						<el-input v-model="editObj1.writer"></el-input>
					</el-form-item>
					<el-form-item label="出版社">
						<el-input v-model="editObj1.publish"></el-input>
					</el-form-item>
				</el-form>
			</div>
			<span slot="footer" class="dialog-footer">
				<el-button @click="dialogVisible1 = false">取 消</el-button>
				<el-button type="primary" @click="confirm1">确 定</el-button>
			</span>
		</el-dialog>
		<!-- 编辑框 -->
		<el-dialog title="编辑书籍信息" :visible.sync="dialogVisible" width="30%" :before-close="handleClose">
			<div>
				<el-form ref="form" :model="editObj" label-width="80px">
					<el-input type="hidden" v-model="editObj.id"></el-input>
					<el-form-item label="书名">
						<el-input v-model="editObj.name"></el-input>
					</el-form-item>
					<el-form-item label="作者">
						<el-input v-model="editObj.writer"></el-input>
					</el-form-item>
					<el-form-item label="出版社">
						<el-input v-model="editObj.publish"></el-input>
					</el-form-item>
				</el-form>
			</div>
			<span slot="footer" class="dialog-footer">
				<el-button @click="dialogVisible = false">取 消</el-button>
				<el-button type="primary" @click="confirm">确 定</el-button>
			</span>
		</el-dialog>


	</div>

</template>

2.制作好模板之后，就得编写一下各个方法，包括显示数据方法（getnetword）增加方法(adduser)，删除方法(deleteRow)，查找方法(check)，修改方法(edit)。

//显示方法
getnetwork() {
				// console.log(this.bookinfo.id);
				var that = this
				this.$axios.post("http://localhost:8081/springboot/getuser")
					.then(function(res) {
						console.log(res.data)
						that.bookInfo = res.data
						// console.log(this.bookInfo)
					}).catch(function(err) {
						console.log(err)
					})
			},


//查询方法
check() {
				// console.log(this.bookname)
				var that = this
				//网络请求获取数据axios
				this.$axios.post("http://localhost:8081/springboot/checkbyname", {
						name: this.bookname,
					})
					.then(function(res) { //请求成功，方法回调
						//回调方法不能用this
						console.log(res.data)
						console.log(res.data.data)
						that.bookInfo = res.data.data
						// console.log(this.data.id)

					}).catch(function(err) { //请求失败
						console.log(err)
					})
			},


//增加方法
	confirm1() {

				var that = this
				//网络请求获取数据axios
				this.$axios.post("http://localhost:8081/springboot/adduser", {
						name: this.editObj1.name,
						publish: this.editObj1.publish,
						writer: this.editObj1.writer
					})
					.then(function(res) { //请求成功，方法回调
						//回调方法不能用this
						that.getnetwork()
						console.log(res.data)
						that.newsList = res.data
					}).catch(function(err) { //请求失败
						console.log(err)
					})



				this.dialogVisible1 = false;
				// Vue.set(this.tableData, this.userIndex, this.editObj);
			}

//删除方法
deleteRow(bookid) {

				console.log(bookid)
				if (confirm('确定要删除吗') == true) {
					var that = this
					//网络请求获取数据axios
					this.$axios.post("http://localhost:8081/springboot/deletebyid", {
							id: bookid

						})
						.then(res => { //请求成功，方法回调
							//回调方法不能用this
							this.getnetwork()
							// getnetwork();
							console.log(res.data)
							that.newsList = res.data
							// console.log(this.newsList);
						}).catch(function(err) { //请求失败
							console.log("失败了" + err)
						})
				}

				// window.location.href = 'http://127.0.0.1:8848/HelloVue/book.html'
			},

//修改方法
confirm() {//确认修改
				console.log(this.editObj.id)
				console.log(this.editObj.name)
				console.log(this.editObj.publish)
				console.log(this.editObj.writer)
				var that = this
				//网络请求获取数据axios
				this.$axios.post("http://localhost:8081/springboot/updateuser", {
						id: this.editObj.id,
						name: this.editObj.name,
						publish: this.editObj.publish,
						writer: this.editObj.writer
					})
					.then(function(res) { //请求成功，方法回调
						//回调方法不能用this
						that.getnetwork()
						console.log(res.data)
						that.newsList = res.data
					}).catch(function(err) { //请求失败
						console.log(err)
					})



				this.dialogVisible = false;
				// Vue.set(this.tableData, this.userIndex, this.editObj);
			},
