Obtaining a value from an input field in Vue.js

Question

Obtaining a value from an input field in Vue.js

Just starting out with Vue and could use a hand extracting a value from an input field:

Here's what I have in my form:

<input type="hidden" id="groupId" value="1">

If I were using jQuery, I would do the following:

var group_id = $('#groupId').val();

However, I'm unsure how to bind the hidden field in Vue:

<div id="app">
   <input type="text" v-model="groupId"> //Where should I place the value?
</div>

new Vue({
    el: '#app',
    data: {
        groupId: //What should I include here to obtain the field's value?
    }

Any tips on how to accomplish this?

Latest Update: Refer to this answer for the most recent information. The previous update contained inaccurate details.

The initial response remains the same:

When working with Vue, it is important to note that data interactions are managed by the viewmodel. Your role is to manipulate data in the viewmodel and establish bindings in the view to ensure synchronization with Vue. To bind an input to your model data item, use the following code snippet:

<input type="hidden" id="groupId" v-model="groupId">

Remember to set the value in the viewmodel as shown below:

data: {
    groupId: 1
}

When grappling with the same issue while utilizing Vue + Laravel, I found a simple solution despite the lack of clarity in the Vue documentation.

To resolve it, all I had to do was:

document.getElementById('MyId').value;

You can find more details here: https://www.w3schools.com/jsref/prop_text_value.asp

Although not the most efficient method, it serves its purpose for now!

Best regards.

Answer №4

this piece of code has proven to be quite helpful for me. I trust that you will also find it beneficial.

start by defining the input

        <div class="container">
            <input type="hidden" ref="userId" value="1">
            <button type="button" v-on:click="fetch_data()">test</button>
        </div>

proceed by defining the method

new Vue({
  el: ".container",
  data: {
    userId: null,
  }
  methods: {
    fetch_data() {
      this.userId = this.$refs.userId.value;
    }
  }
});

// To display the value on your webpage, simply include {{ groupId }}

/* The value can be retrieved using @change.enter=".." or @keypress.enter="getInputValue",

Answer №6

In Vue.js, retrieving user input can be achieved by utilizing the v-model directive to establish a bi-directional binding between the input value and a data variable.

<template>
  <div id="app">
    <input
      type="text"
      v-model="textInput"
      placeholder="Enter text"
      @input="handleInput"
    />
    <br />
  </div>
</template>
<script>
export default {
  data() {
    return {
      textInput: '',
    };
  },
  methods: {
    handleInput(event) {
      console.log(event.target.value);
    },
  },

Check out this code I wrote using Laravel, Vuejs, Vuetable2, and child rows without using the v-model:

this.$refs['est_'+id_det].localValue

In Vue:

<div class="col-md-3">
<b-form-select class="form-control selectpicker" :ref="'est_'+props.row.id_detalle_oc"
 :value="props.row.id_est_ven" v-on:change="save_estado(props.row.id_detalle_oc)">
    <option value="0">No state</option>
    <option value="1">Pending</option>
    <option value="2">Printed</option>
    <option value="3">Ready</option>
</b-form-select>

Within methods:

methods: {
        save_estado:function (id_det){
            var url= 'ordenes-compra/guardar_est_ven'
            var id_estado = this.$refs['est_'+id_det].localValue
             axios.post(url,{
                id_det: id_det,
                id_est_ven: id_estado,
                est_ven: est_ve
            }).then(function (response) {
                var respuesta= response.data;
                if(respuesta == "OK"){
                swal({
                        type: 'success',
                        title: 'Success!',
                        text: 'State modified',
                        confirmButtonText: 'Understood',
                    })
                }
            })
            .catch(function (error) {
                console.log(error);
            });
        },

Hey there! Another option to consider is:

const element = this.$el.firstElementChild;

If you are working with TypeScript, define the element as:

: HTMLInputElement

After that, retrieving the value is as easy as:

element.value

I hope this solution proves useful to you!
