Vue.js 中 Chrome 和 Datalist 的性能问题

好了，我终于找到了导致Chrome出现如此多性能问题的元素.

数据列表上不再有"值":

 <b-input-group size="sm">
  <b-form-input
    :list="`mealDish${meal.id}`"
    :id="`input${meal.id}`"
    placeholder="Selectionner un plat"
    v-model="name"
  />
  <datalist :id="`mealDish${meal.id}`">
    <option v-for="dish in activeDishesByType" :data-value="dish.id">{{
      `${dish.name} (${dish.humanType})`
    }}</option>
  </datalist>
  
  <b-input-group-append>
    <b-button variant="primary" @click="onClick" :disabled="loading">
      <i :class="loading ? 'fa fa-spin fa-circle-notch' : 'fa fa-plus'" />
    </b-button>
  </b-input-group-append>
</b-input-group>

以及在数据列表选项中搜索以返回我的数据值:

  // Get the selected/typed value
  const shownVal = document.getElementById(`input${this.meal.id}`).value;
  const datalist = document.querySelector(`#mealDish${this.meal.id}`);
  // Find the option in the list and get the data-value (id)
  let dishId = null;
  for (var i = 0; i < datalist.options.length; i++) {
    if (datalist.options[i].text === shownVal) {
      dishId = datalist.options[i].dataset.value;
      break;
    }
  }
