我有一个 div 元素的嵌套结构，其中最里面的子元素包含一个工具提示。父容器（父类）具有 CSS 属性

<div class="child_level_four">
<div class="tooltip">
<p>tooltip text</p>
</div>
</div>
</div>
</div>
</div>
</div>
document.querySelectorAll(".tooltip_container").forEach((tooltip) => {
const tooltipText = tooltip.getAttribute("data-tooltip");
const tooltipContent = document.createElement("div");
tooltipContent.className = "tooltip_content";
tooltipContent.innerText = tooltipText;
tooltip.appendChild(tooltipContent);
});.parent_class {
