Answer 1

您应该在模板中使用show而不是show.value。show.value仅在合成api的script标签中可用。

<template>
<div class="d-flex cursor-pointer justify-content-between border rounded bg-white mt-4 p-2 w-100 " @click="dropdown">
<span>Purchase Requsition</span>
<span class="material-icons fs-28 text-primary">
{{show ? 'arrow_circle_down' : 'arrow_circle_down' }}
</span>
</div>
</template>
