是否删除div折叠时的链接文本？

<style>
    .collapsed-link {
        text-decoration: none;
    }
</style>

<div class="collapsed-link">
    <a href="#">链接文本</a>
</div>

<script>
    document.querySelector('.collapsed-link a').innerHTML = '';
</script>

<div class="collapsed-link">
    <a href="#">链接文本</a>
</div>
