目的：用vue实现简单的增删该查
注：我自己测试的后台是java+mysql。 这里提供前端页面。 只需要连接你的后台url就好了
需要准备 vue.js 和 bootstrap.css
代码如下
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
</head>
<script type="text/javascript" src="js/vue.js" ></script>
<link rel="stylesheet" href="css/bootstrap.css" />
<body>
<div id="app">
<div class="panel panel-primary">
<div class="panel-heading">
<h3 class="panel-title">添加品牌</h3>
</div>
<form @submit.prevent="submit">
<div class="panel-body form-inline">
<label>
Id:
<input type="text" name="id" v-model="addData.id" class="form-control">
</label>
<label>
Name:
<input type="text" v-model="addData.name" class="form-control"/>
</label>
<label>
Age:
<input type="text" v-model="addData.age" class="form-control"/>
</label>
<input type="submit" value="添加" class="btn btn-primary"/>
</div>
</form>
</div>
<table class="table table-bordered table-hover table-striped">
<thead>
<tr>
<th>Id</th>
<th>Name</th>
<th>Age</th>
<th>删除</th>
</tr>
</thead>
<tbody>
<tr v-for="item in content" :key="item.id">
<th>{{ item.id }}</th>
<th>{{ item.name }}</th>
<th>{{ item.age }}</th>
<th>
<a href="" @click.prevent="del(item.id)">删除</a>
</th>
</tr>
</tbody>
</table>
</div>
<script>
var vm = new Vue({
el:'#app',
data:{
content: [
{
id: '',
name: '',
age: ''
}
],
addData:{},
},
created() { //当vm实例的data和methods 初始化完毕后，vm实例会自动执行这个方法
this.getAllList();
},
methods:{
getAllList() { //获取列表的全部信息
//这个url填写你获取数据的地址 我的地址http://localhost:8080/ssm/select.action
var url = ''
fetch(url,{
method: 'get'
})
.then(res => {
return res.json()
})
.then(data => {
console.log(data);
this.content = data;
})
},
submit: function () {
let data = JSON.stringify(this.addData)
this.addData = {}
//这个url添加你添加数据的地址
let url = ''
fetch(url, {
method: 'POST',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
},
body: data
}).then((res) => {
this.getAllList()
console.log(res);
})
},
del(id) {
let url = 'http://localhost:8080/ssm/del.action?id='+id
fetch(url, {
method: 'get',
}).then((res) => {
this.getAllList()
console.log(res);
})
}
}
})
</script>
</body>
</html>
页面如下：
