- 点击提交按钮，发送ajax请求 ， 携带表单JSON数据 ， 使用
v-model
- 后台接收请求，查询接收到的品牌数据
- 调用对应的service方法添加数据
- 响应成功标识
- 获取数据，判断是否添加成功，跳转到查询所有数据页面
1.5.3.2 编码
- 引入Vue的JS文件（不再赘述）
- 创建Vue对象
new Vue({el: "#app",data(){return {brand:{}}},methods: {// 发送AJAX请求submitFrom() {// Axios无法直接使用原生的thisvar _this = this;axios({method: "post",url: "http://localhost:8080/brand-demo-ajax/add",// Axios传递参数时会自动将JavaScriptObject序列化为JSON串data: _this.brand}).then(function (resp){// 判断响应数据是否为 successif (resp.data =https://www.huyubaike.com/biancheng/="success") {// 重定向到查询所有页面location.href = "http://localhost:8080/brand-demo-ajax/brand.html";}})}}}) - 修改视图
