Configuring input properties using props and the <script setup> tag

Question

Configuring input properties using props and the <script setup> tag

Is there a way to utilize props to define the input type in a form?

The method below doesn't appear to be effective, are there any alternative approaches?

For instance

<script setup>
defineProps({
  InputType: String,
  InputId: String,
  InputLabel: String,
  InputPlaceholder: String
});
</script>

<template>
  <div class="ml-6 mt-5 mr-6 mb-5 lg:w-1/2">
    <label
      :for="InputId"
      class="block text-sm font-medium leading-6 text-gray-900"
    >
      {{ InputLabel }}
    </label>
    <div class="mt-2">
      <input
        :id="InputId"
        :type="InputType"
        class="block w-full rounded-md border-0 py-1.5 text-gray-900 shadow-sm ring-1 ring-inset ring-gray-300 placeholder:text-gray-400 focus:ring-2 focus:ring-inset focus:ring-pink-600 sm:text-sm sm:leading-6"
        :placeholder="InputPlaceholder"
      />
    </div>
  </div>
</template>

Answer №1

It is important to carefully review the documentation on how to effectively utilize props with the <script setup> feature. Make sure to assign a value to defineProps in order for props to be accessible within your template.

const props = defineProps({
    InputType: String,
    InputId: String,
    InputLabel: String,
    InputPlaceholder: String,
})

<label :for="props.InputId">{{ props.InputLabel }}</label>
<div class="mt-2">
  <input :type="props.InputType" :id="props.InputId" v-bind:placeholder="props.InputPlaceholder">
</div>

Keep in mind that props can be automatically unwrapped in your template, allowing you to use InputId instead of props.InputId. However, explicit referencing may be necessary if used elsewhere in the <script setup> section.

In the child component, it is recommended to use props with camelCase names such as inputLabel instead of InputLabel:

defineProps({
  inputType: String,
  inputId: String,
  inputLabel: String,
  inputPlaceholder: String
});

These props should then be used in the parent component like this:

<Child input-label="some label"/>

or

<Child inputLabel="some label"/>

    formField: {type: Object, default: {}}
    }) 
<script>
    
<template>
    <div v-if="type === 'text'">
        Rendering text input here
    </div>
    <div v-if="type === 'file'">
        Rendering file upload input here
    </div>
    <div v-if="type === 'checkbox'">

Here is a simple solution to your query.

If you ever find yourself needing to refresh your Vue component, take a look at this guide on How to force a Vue component to re-render.

const { createApp } = Vue

const MyInput = {
  props: ['type'],
  template: 'Type: {{type}} <br/> <input :type="type" />'  
}

const App = {  
  components: {
    MyInput
  },
  data() {
    return {
      type: 'text',
      types: ['text', 'radio', 'checkbox']
    }
  },
}

const app = createApp(App)
app.mount('#app')

#app { line-height: 1.75; }
[v-cloak] { display: none; }

<div id="app" v-cloak>
  Type: <select v-model="type">
  <option v-for="t in types">{{t}}</option>
  </select><br/>
  <my-input :type="type"></my-input>
</div>
<script src="https://unpkg.com/vue@3/dist/vue.global.prod.js"></script>
