好的设计思路：

​
<template>
  <div>
    <!-- Task Display -->
    <div>
      <h2>Task {{ currentTask.id }}: {{ currentTask.name }}</h2>
      <p>{{ currentTask.details }}</p>
      <img ref="mapAll" id="mapAll" src="../../assets/images/JIESHOUJI.png" usemap="#image-map">
      <map v-if="currentHotspots" name="image-map">
        <area v-for="(area, index) in currentHotspots" :key="index" :id="area.id" :title="area.title" :coords="area.coords" :shape="area.shape" @click="handleClick(area)">
      </map>
    </div>

    <!-- Global Navigation Buttons -->
    <div>
      <button @click="previousTask" :disabled="currentTaskIndex === 0">Previous</button>
      <button @click="nextTask" :disabled="currentTaskIndex === tasks.length - 1">Next</button>
    </div>
  </div>
</template>
