删除按钮在 vue-bootstrap 中产生多个确认模式>

Question

希望通过在此循环中对模态具有唯一引用来解决此问题，尝试在最后给 ref 一个grade.id，但不适用于带有 b-modal ref 的字符串插值，也尝试过：ref .

这是 vue 文件中的代码，下面是它的截图，当我按下删除等级时，它会显示所有模态，因为模态处于循环状态。

Answer 1

您可以将模式移到循环之外。要传递点击成绩的数据，只需将其保存到您的数据中，例如“activeGrade”。在您的模式中，您显示“activeGrade”的数据。现在您可以使用点击的成绩特定数据打开（相同的）模态。

我稍微简化了您的代码以仅显示所询问的问题：

<template>
  <div class="hello">
    <b-card-group class="mb-4" v-for="grade in grades" :key="grade.id">
      <b-card :title="grade.title">
        <b-card-text class="list-card">
          Some Text (grade properties)

          <span style="float: right">
            <b-button
              class="mr-1"
              type="reset"
              variant="danger"
              @click="showModal(grade)"
              size="sm">
              <!-- Fix css to icon middle -->
              <b-icon icon="trash-fill" size="is-small"></b-icon>
            </b-button>
          </span>
        </b-card-text>
      </b-card>
    </b-card-group>

    <b-modal v-if="activeGrade"
            scrollable
            id="modal-delete-grade"
            centered
            @ok="actionDelete(activeGrade.id)"
            class="d-block text-center"
            title="Confirm Delete Grade">
      <p>
        Confirm that you are about to delete grade
        {{ activeGrade.title }}
      </p>
    </b-modal>
  </div>
</template>

<script>
export default {
  data() {
    return {
      grades: [
        { id: 1, title: 'Grate 1' },
        { id: 2, title: 'Grate 2' },
        { id: 3, title: 'Grate 3' },
      ],
      activeGrade: null
    }
  },
  methods: {
    actionDelete(gradeId) {
      console.log('delete ' + gradeId)
    },
    showModal(grade) {
      this.activeGrade = grade

      this.$nextTick(() => {
        this.$bvModal.show("modal-delete-grade");
      })
    }
  }
}
</script>
