Ensuring that Vue3 Typescript app focuses on input element within Bootstrap modal upon opening

I am facing a challenge with setting the focus on a specific text input element within a modal dialog. I have tried various methods but none seem to achieve the desired outcome. Here is what I have attempted:

Attempt 1: Using autofocus attribute.

<input placeholder="Enter search text" type="text" autofocus class="form-control" v-model="searchterm"/>

The input does not focus, and there are no errors...

Attempt 2: Implementing a custom directive (v-focus) on the input element.

<input placeholder="Enter search text" type="text" v-focus class="form-control" v-model="searchterm"/>


<script lang="ts">

import { defineComponent, PropType } from "@vue/runtime-core";
export default defineComponent({
  name: "Crops-view",
  setup() {
  },
  directives: {
    focus: {
      mounted: (el) => {
        el.focus();
        console.log("focus set");
      },
    },
  props: { ...   ...},
});
</script>

This method triggers the routine at page load instead of when the modal dialog opens. It won't work for multiple dialogs with individual initial focus points.

Attempt 3: Utilizing watch to trigger function upon change in dialog visibility.

<div
    class="modal fade m-3 p-3 justify-content-center"
    id="crops-modal"
    data-bs-backdrop="static"
    v-show="showCropsModal"
 
  >
    <div class="modal-dialog">
      <div class="modal-content">
        <div class="modal-header">
          <div class="title text-center">Crops</div>
        </div>
        <div class="row m-2">
          <input
            placeholder="Enter search text"
            type="text"
            class="form-control"
            v-model="searchterm"
          />
        </div>
      </div>
    </div>
  </div>
</div>

<script lang="ts">

import { defineComponent, PropType, ref } from "@vue/runtime-core";
export default defineComponent({
  name: "Crops-view",
  setup() {
    const showCropsModal = true;
    const cropsearchinput = ref<HTMLInputElement>();
    return { showCropsModal, cropsearchinput};
  },
  watch: {
    showCropsModal(value) {
      if (value) {
        (cropsearchinput.value as HTMLElement).focus();
      }
    },
  },
  props: { ...   ...},
});
</script>

This code does not compile and throws a lint error stating 'cropsearchinput' is not defined.

I have explored various options including directives, methods, watches, v-focus, and autofocus.

Answer №1

If someone is facing a similar issue,

here is how I resolved it:

<script setup lang="ts">
import { ref, watch } from 'vue'

const modalActive = ref<boolean>(false)
const btnRef = ref<HTMLButtonElement>()

watch(modalActive, (newVal: boolean) => {
  if (newVal == true) {
    setTimeout(() => {
      btnRef.value!.focus()
    }, 100)
  }
})
</script>

Answer №2

When working with the Vue3 Composition API, you have the ability to create a reference to an input field and then utilize the onMounted callback function to determine when the component is ready for the input to receive focus:

<script setup>

import {onMounted, ref} from "vue";

const inputField = ref(null);

onMounted(() => {
    setTimeout(() => {
        inputField.value.focus()
    }, 250);
});

<template>
    <TextInput ref="inputField" v-model="formData.fieldName" />
</template>

</script>
