【Vuetify】v-autocompleteのsearch-inputをデバウンスして0.5秒後に入力された値のみでデータを取得

Last updated at Posted at 2023-01-22

個人の備忘録です。

環境

  • vue: 2.7.x(Composition API / script setup)
  • vuetify: 2.6.x

実現したいこと

困った点

変更前
<script setup lang="ts">
省略

interface State {
  value: string;
  isSearching: boolean;
  users: Response[];
}

const state: State = reactive({
  value: '',
  isSearching: false,
  users: [],
});

const onSearchInput = async (searchName: string) => {
  state.isSearching = true;
  state.users = await repository.getUsers(searchName);
  state.isSearching = false;
};
</script>

<template>
  <v-autocomplete
    v-model="state.value"
    :items="state.users"
    // ここが keydown 毎に発火してしまう
    @update:search-input="onSearchInput"
    :loading="state.isSearching"
  >
  </v-autocomplete>
</template>

解決コード

  • JavaScritp の clearTimeout で古いタイムアウトを解除する

変更後
<script setup lang="ts">
省略

interface State {
  value: string;
  isSearching: boolean;
  users: Response[];
  timerId?: ReturnType<typeof setTimeout>;
}

const state: State = reactive({
  value: '',
  isSearching: false,
  users: [],
  timerId: undefined,
});

const onSearchInput = (searchName: string) => {
  state.isSearching = true;

  // 古いタイムアウトは解除する
  clearTimeout(state.timerId);

  // 0.5秒後に発火する
  state.timerId = setTimeout(async () => {
    state.users = await repository.getUsers(searchName);
    state.isSearching = false;
  }, 500);
};
</script>

<template>
  <v-autocomplete
    v-model="state.value"
    :items="state.users"
    @update:search-input="onSearchInput"
    :loading="state.isSearching"
  >
  </v-autocomplete>
</template>
