小程序表单的默认值

因为下面一开始定义了个数组 修改完后的值都放在 name 里

如何获取修改的id

onLoad:function(option){
let id = options.id; //获取到修改的id
}

<template>
  <div>
    <div>
      姓名：
      <input type="text" v-model="name.name" class="box" />
      内容：
      <input type="text" v-model="name.contents" class="box" />
      类型：
      <input type="text" v-model="name.type" class="box" />
    </div>
    <div>
      <button @click="update">修改</button>
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      name: ""
    };
  },
  onLoad: function(options) {
    let id = options.id;
    console.log(id);

    let t = this;
    wx.request({
      url: "http://127.0.0.1/laravel/public/mail/edit?id=" + id, // 仅为示例，并非真实的接口地址
      data: {},
      header: {
        "content-type": "application/json" // 默认值
      },
      success(res) {
        console.log(res.data);
        t.name = res.data;
      }
    });
  },
  methods: {
    update() {
      wx.request({
        url:
          "http://127.0.0.1/laravel/public/mail/update?id=" +
          this.name.id +
          "&name=" +
          this.name.name +
          "&contents=" +
          this.name.contents +
          "&type=" +
          this.name.type, // 仅为示例，并非真实的接口地址
        data: {},
        header: {
          "content-type": "application/json" // 默认值
        },
        success(res) {
          console.log(res);
          wx.navigateTo({
            url: "../lian/main"
          });
        }
      });
    }
  }
