如何使用从 API 获取的数据填写表格？

Question

我制作了用户信息页面，用户可以更改和更新他们的信息。 我想显示数据并使用获取请求数据自动填写表单输入。

是否可以选择只调用 userinfo 并填写所有输入？ 或者我应该为我的所有输入（如名字、姓氏等）做同样的事情this.username = res.data吗？ 这是我的方法：

<script>

import axios from 'axios'
export default {
  name:'ProfilePage',
  data(){
    return{
      isEditable:false,
      isHidden:false,
      username:"",
      userinfo:[]
    }
  },
  methods:{
    getProfile(){
      if(this.$route.params.id == undefined ||  this.$route.params.id == null){
        axios.get(`/v1/management/update_user/`)
            .then(res=>{console.log(res)
              this.username = res.data

            })
      }else {
        axios.get(`/v1/management/update_user/${this.$route.params.id}`)
            .then(res=>{console.log(res)
              this.username = res.data
            })
      }
    },
    editProfile(){
      this.isEditable = !this.isEditable
    },
    saveProfile(){

    },
    passwordModal(){

    },
    checkResetPassword(){
      if(this.new_pass!== this.new_pass_con){
        this.$toasted.error("Şifreler farklı!"),{
          action: {
            text: 'Kapat',
            onClick: (e, toastObject) => {
              toastObject.text("").goAway(10);
            }
          }
        }

      }else {
        this.$toasted.success("İşlem başarılı!"),{
          action: {
            text: 'Kapat',
            onClick: (e, toastObject) => {
              toastObject.text("").goAway(10);
            }
          }
        }
      }
    }
  },
  mounted() {
    this.getProfile()
  }
}


</script>

更新

<template>
  <div>
    <div class="form-group">
      <label for="username">Username</label>
      <input id="username" type="text" class="form-control" placeholder="Username" :value="userinfo.username" disabled>
      <input id="email" type="text" class="form-control" placeholder="email" :value="userinfo.email" disabled>
      <input id="website" type="text" class="form-control" placeholder="website" :value="userinfo.website" disabled>
      <button @click="fetchUser">fetch some user</button>
      <p>Actual user info object: <pre>{{ userinfo }}</pre></p>
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      userinfo: {}
    }
  },
  methods: {
    async fetchUser() {
      const response = await fetch('https://jsonplaceholder.typicode.com/users/1')
      const data = await response.json()
      this.userinfo = data
    },
  }
}
</script>

这种基本代码应该完全有效

<template>
  <div>
    <div class="form-group">
      <label for="username">Username</label>
      <input type="text" class="form-control" id="username" placeholder="Username" :value="username" disabled>
      <button @click="fetchUser">fetch some user</button>
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      username: 'nick'
    }
  },
  methods: {
    async fetchUser() {
      const response = await fetch('https://jsonplaceholder.typicode.com/users/1')
      const data = await response.json()
      this.username = data.username
    },
  }
}
</script>

这里是游乐场。

您可以使用v-model将数据绑定到表单字段中。 出于演示目的而不是v-for ，我直接绑定基于索引的值。

工作演示：

 const app = new Vue({ el: '#app', data() { return { userInfo: [] } }, mounted() { this.getProfile(); }, methods: { // Just for demo I am directly assigning the mock response in userInfo array. You can replace that with API call response. getProfile() { this.userInfo = [{ username: 'alpha' }] } } })

 <script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script> <div id="app"> UserName: <input type="text" v-model="userInfo[0].username"> </div>
