你好noobie又卡住了。所以我已经获取了所有这些锻炼并将它们呈现在我的模板中。单击详细信息按钮时会显示更多数据，但问题是所有按钮都被激活但我只想打开我单击的按钮。我想我需要定位正确的 id 但注意到我已经尝试过：/

    <div class="wrapper">
      <div class="workouts" v-for="workout in workouts" :key="workout.id">
        <div class="card-item-container">
          <img v-if="mens" :src="workout.male.image" />
          <img v-else :src="workout.female.image" />
        </div>
        <div class="card-item-content">
          <h3>{{ workout.name }}</h3>
          <button @click="showModal = true">Details</button>
        </div>
 
        <div class="modal" v-if="showModal">
          <h3>
            Mouscle groups: {{ workout.bodyAreas[0] }}
            {{ workout.bodyAreas[1] }}
          </h3>
          <b v-html="workout.transcript"> </b>
          <button class="close" @click="showModal = false">close</button>
        </div>

<script>
export default {
  components: {},
  data() {
    return {
      mens: true,
      womens: true,
      showModal: false,
    };
  },

  methods: {
    toggleMens() {
      this.mens = true;
      this.womens = false;
    },
    toggleWomens() {
      this.womens = true;
      this.mens = false;
    },
  },

  computed: {
    workouts() {
      return this.$store.state.workouts;
    },
  },

  async mounted() {
    await this.$store.dispatch("fetchWorkouts");
  },
};
</script>

每个模态的 v-if 都绑定到相同的 showModal 值。因此，它们 show/hide 基于相同的变量变化。

我会为每个组件创建一个新组件，使用它们自己的本地 showModal 变量。

我也会使用 v-show 而不是 v-if。内容很轻，不需要从 DOM.

add/remove

//Parent.vue
<script>
import Workout from "./Workout.vue"
...
  components: { Workout }
...
</script>
<template>
  <div v-for="workout in workouts" ...>
    <Workout workout="workout" />
  </div>
</template>

//Workout.vue
<script>
...
    data () {
      return {
        showModal: false
      }
    },
    props: { workout }
...
</script>
<template>
  <img ... />
  <h2>...</h2>
  <button></button>
  <div v-show="showModal">
    {{workout....}}
  </div>
</tamplate>
