更新時間：2022年03月03日 16:29:34 作者：陶然同學。
這篇文章主要為大家詳細介紹了Vue項目之學生管理系統(tǒng)實例，文中示例代碼介紹的非常詳細，具有一定的參考價值，感興趣的小伙伴們可以參考一下，希望能夠給你帶來幫助
查詢學生
步驟1：設置導航
步驟2：添加路由
步驟3：創(chuàng)建頁面
步驟：
- 步驟1：準備2個變量（pageInfo、studentVo）
- 步驟2：編寫查詢condition函數，接收參數num
- 步驟3：頁面加載成功時，查詢第一頁
- 步驟4：遍歷結果
<template>
<div>
班級： <select v-model = "studentVo.cid">
<option value="" disabled>--請選擇--</option>
<option :value="classes.cid" v-for = "(classes,index) in classesList" :key = "index">{{classes.cname}}</option>
</select>
姓名：<input type="text" v-model = "studentVo.studentName">
年齡：<input type="text" v-model = "studentVo.startAge">——<input type="text" v-model = "studentVo.endAge">
<input type="button" value = "查詢" @click = "conditionStudent()">
<table border="1">
<tr>
<td>ID</td>
<td>班級</td>
<td>姓名</td>
<td>年齡</td>
<td>生日</td>
<td>性別</td>
<td>操作</td>
</tr>
<tr v-for = "(student,index) in pageInfo.list" :key="index">
<td>{{student.sid}}</td>
<td>{{student.classes == null ? student.cname : student.classes.cname}}</td>
<td>{{student.sname}}</td>
<td>{{student.age}}</td>
<td>{{student.birthday}}</td>
<td>{{student.gender == 1 ? '男' : '女'}}</td>
<td>
<router-link :to="{path:'/studentEdit',query:{sid : student.sid}}">修改</router-link>
<router-link to="" @click.native.prevent = "deleteStudent(student.sid)">刪除</router-link>
</td>
</tr>
</table>
<!-- 分頁 start -->
當前第 {{pageInfo.pageNum}}頁，共{{pageInfo.pages}}頁, 總計數{{pageInfo.total}}條,
每頁 <select v-model = "pageInfo.pageSize" @change = "conditionStudent(1)">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="5">5</option>
<option value="10">10</option>
</select>條
<a href="" v-if = "!pageInfo.isFirstPage" @click.prevent = "conditionStudent(1)">首頁</a>
<a href="" v-if = "pageInfo.hasPreviousPage" @click.prevent = "conditionStudent(pageInfo.pageNum - 1)">上一頁</a>
<a href="" v-for = "(num,index) in pageInfo.pages" @click.prevent = "conditionStudent(num)" :key="index">{{num}}</a>
<a href="" v-if = "pageInfo.hasNextPage" @click.prevent = "conditionStudent(pageInfo.pageNum - 1)">下一頁</a>
<a href="" v-if = "!pageInfo.isLastPage" @click.prevent = "conditionStudent(pageInfo.pages)">尾頁</a>
跳轉到 <input v-model = "pageInfo.pageNum" placeholder="enter跳轉" @keyup.enter = "conditionStudent()"> 頁
<!-- 分頁 end -->
</div>
</template>
<script>
import axios from 'axios'
export default {
data() {
return {
classesList:[],
studentVo: {
cid:''
},
pageInfo:{
pageNum:1,
pageSize:2
}
}
},
methods:{
async selectClasses(){
let { data: baseResult } = await axios.get("http://localhost:8888/classes");
this.classesList = baseResult.data
},
async conditionStudent(num){
if(num){
this.pageInfo.pageNum = num
}
var url = `http://localhost:8888/student/condition/${this.pageInfo.pageSize}/${this.pageInfo.pageNum}`;
let {data: baseResult} = await axios.post(url,this.studentVo);
this.pageInfo = baseResult.data
},
},
mounted(){
//查詢所有班級
this.selectClasses();
//查詢所有學生
this.conditionStudent();
}
}
</script>
<style>
</style>添加學生
步驟1：設置導航
步驟2：添加路由
步驟3：創(chuàng)建頁面
步驟：
- 創(chuàng)建數據 班級數組 和 學生對象
- 班級數據跟select綁定 table綁定學生對象
- 發(fā)送post請求添加學生
<template>
<div>
<table border="1">
<tr>
<td>ID</td>
<td>
<input type="text" v-model = "student.sid">
</td>
</tr>
<tr>
<td>班級</td>
<td>
<select v-model = "student.cid">
<option value="">--請選擇--</option>
<option :value="classes.cid" v-for = "(classes,index) in classesList" :key="index">{{classes.cname}}</option>
</select>
</td>
</tr>
<tr>
<td>姓名</td>
<td>
<input type="text" v-model = "student.sname">
</td>
</tr>
<tr>
<td>年齡</td>
<td>
<input type="text" v-model = "student.age">
</td>
</tr>
<tr>
<td>生日</td>
<td>
<input type="date" v-model = "student.birthday">
</td>
</tr>
<tr>
<td>性別</td>
<td>
<input type="radio" v-model = "student.gender" value = "1"> 男
<input type="radio" v-model = "student.gender" value = "0"> 女
</td>
</tr>
<tr>
<td colspan="2">
<input type="button" value = "添加學生" @click = "addStudent()">
</td>
</tr>
</table>
</div>
</template>
<script>
import axios from 'axios'
export default {
data() {
return {
classesList:[],
student:{}
}
},
methods:{
async selectClasses(){
let {data:baseResult} = await axios.get(`http://localhost:8888/classes`);
this.classesList = baseResult.data
},
async addStudent(){
var url = "http://localhost:8888/student";
let { data: baseResult } = await axios.post(url,this.student);
if(baseResult.code == 20000){
this.$router.push('/studentList')
}else{
alert(baseResult.message)
}
}
},
mounted(){
//查詢所有班級
this.classesList = this.selectClasses();
}
}
</script>
<style>
</style>修改學生
步驟1：設置導航
步驟2：添加路由
步驟3：創(chuàng)建頁面
步驟：
- 先獲得路由傳參傳過來的參數 存儲到data數據區(qū)域 cid
- 根據cid查詢到學生 存儲到student table對student進行數據雙向關聯
- 修改學生信息 發(fā)送ajax請求
<template>
<div>
<table border = "1">
<tr>
<td>編號</td>
<td>
{{ classes.cid }}
</td>
</tr>
<tr>
<td>班級名稱</td>
<td>
<input type="text" v-model = "classes.cname">
</td>
</tr>
<tr>
<td>班級描述</td>
<td>
<textarea name="" id="" cols="30" rows="10" v-model = "classes.desc"></textarea>
</td>
</tr>
<tr>
<td colspan="2">
<input type="text" value = "修改" @click = "editClasses()">
</td>
</tr>
</table>
</div>
</template>
<script>
import axios from 'axios';
export default {
data() {
return {
classes:{},
cid:'',
};
},
methods:{
async selectClassesById(){
let url = `http://localhost:8888/classes/${this.cid}`;
let { data: baseResult } = await axios.get(url);
this.classes = baseResult.data
},
async editClasses(){
var url = `http://localhost:8888/classes`;
let { data: baseResult } = await axios.put(url,this.classes);
if(baseResult.code == 20000){
this.$router.push("/classesList");
}else{
alert(baseResult.message);
}
}
},
mounted(){
//獲得cid
this.cid = this.$route.params.cid;
//根據id查詢班級信息
this.selectClassesById();
}
}
</script>
<style>
</style>刪除學生
步驟1：設置導航
步驟2：添加方法
步驟：
- 根據cid發(fā)送ajax刪除學生
<template>
<div>
班級： <select v-model = "studentVo.cid">
<option value="" disabled>--請選擇--</option>
<option :value="classes.cid" v-for = "(classes,index) in classesList" :key = "index">{{classes.cname}}</option>

姓名：<input type="text" v-model = "studentVo.studentName">
年齡：<input type="text" v-model = "studentVo.startAge">——<input type="text" v-model = "studentVo.endAge">
<input type="button" value = "查詢" @click = "conditionStudent()">
