Guide on populating a Vue.js input field with a value retrieved from a JSON object

Could someone please assist me with a problem I am encountering? I need to extract and display the values from an input form for "name" and "position", but the data is in JSON format.

{"id":5,"name":"the name","pos":"the position"}

This code snippet represents a template in HTML using Vue.js

<template>
  <div class="container">
    <div class="row justify-content-center">
      <div class="col-md-8">
        <div class="card">
          <div class="card-header">
            Edit <b>{{name}}</b>
          </div>
          <div class="card-body">
            <form @submit="edit()" method="post" onclick="return false">
              <div class="form-group">
                <label for="">Name</label>
                <input v-model="input.nameInput" type="text" value="?" autocomplete="off" class="form-control">
              </div>
              <div class="form-group">
                <label for="">Position</label>
                <input v-model="input.posInput" value="?" type="text" autocomplete="off" class="form-control">
              </div>
              <button type="submit" class="btn btn-primary">Edit</button>
            </form>
          </div>
        </div>
      </div>
    </div>
  </div>
</template>

This section contains the JavaScript code corresponding to the Vue.js template file

<script>
export default {
  data(){
    return{
        name:'',
        pos:'',
        input:{
          nameInput:'',
          posInput:''
        }
    }
  },
  methods:{
    getEmploye(){
      axios.get('/employes_api/'+this.$route.params.id).then(response => {
        this.name = response.data.name;
        this.pos = response.data.pos;
      });
    },
    edit(){
      axios.put('/employes_api/'+this.$route.params.id, {
        name: this.name,
        pos: this.position,
      }).then(response => {
        this.$route.employe;
      });
    }
  },
  mounted(){
    this.getEmploye();
  }
}
</script>

Your assistance is greatly appreciated!

Answer №1

If the data you receive matches the following format:

{"id":6,"name":"the name","pos":"the position"}

then your fetchEmployee function should look like this:

fetchEmployee(){
  axios.get('/employees_api/'+this.$route.params.id).then(response => {
    this.name = response.name;
    this.position = response.pos;
  });

Answer №2

If you want to show the information retrieved from the api, you can use the code snippet below:

value=“{{name}}”

This code will display the value stored in the name data.

To verify if this is functioning correctly, you can initially assign a placeholder value to the name variable.

Answer №3

Instead of creating separate variables for inputs and display, you can use the same variable for both in Vue. This way, the data will be automatically updated in real-time on the display and input fields as the user types.

So, your data should look like this:

data(){
    return{
        name:'',
        pos:''
    }
},

For the template inputs, you can use:

<input v-model="name" type="text" autocomplete="off" class="form-control">
...
<input v-model="pos" type="text" autocomplete="off" class="form-control">

Your overall template structure should resemble this:

<template>
  <div class="container">
    <div class="row justify-content-center">
      <div class="col-md-8">
        <div class="card">
          <div class="card-header">
            Edit <b>{{name}}</b>
          </div>
          <div class="card-body">
            <form @submit="edit()" method="post">
              <div class="form-group">
                <label for="">Name</label>
                <input v-model="name" type="text" autocomplete="off" class="form-control">
              </div>
              <div class="form-group">
                <label for="">Position</label>
                <input v-model="position" type="text" autocomplete="off" class="form-control">
              </div>
              <button type="submit" class="btn btn-primary">Edit</button>
            </form>
          </div>
        </div>
      </div>
    </div>
  </div>
</template>

<script>
export default {
  data(){
    return{
        name:'',
        pos:''
    }
  },
  methods:{
    getEmploye(){
      axios.get('/employes_api/'+this.$route.params.id).then(response => {
        this.name = response.data.name;
        this.pos = response.data.pos;
      });
    },
    edit(){
      axios.put('/employes_api/'+this.$route.params.id, {
        name: this.name,
        pos: this.pos,
      }).then(response => {
        this.$route.employe;
      });
    }
  },
  created(){
    this.getEmploye();
  }
}

Note: If there are any errors in the code, feel free to reach out for assistance.

To implement binding a value with Vue.js, you can use the syntax :value=“name”. For example: <input :value="name"/>.
