如何在做出选择后保持对自定义下拉列表的关注

Question

我有一个自定义下拉菜单，我已经在下拉菜单和其中的项目上设置了焦点状态。但是，当我从第一个菜单中选择一个项目时，焦点会转到导航，而不是下一个下拉菜单。有没有一种方法可以针对第一个下拉列表之后的第二个下拉列表？

如果你愿意的话，这里有一个Codepen。

for (const dropdown of document.querySelectorAll(".custom__select-wrapper:not(.clearFilter)")) {
dropdown.addEventListener("click", function () {
this.querySelector(".custom__select").classList.toggle("open");
});
}
for (const option of document.querySelectorAll(".custom__option")) {
option.addEventListener("click", function () {
if (!this.classList.contains("selected")) {
this.parentNode
.querySelector(".custom__option.selected")
.classList.remove("selected");
this.classList.add("selected");
this.closest(".custom__select").querySelector(
".custom__select-trigger h6"
).textContent = this.textContent;
if (this.getAttribute("data-type")) {
current_story = this.dataset["type"];
}
}
});
}
window.addEventListener("click", function (e) {
for (const select of document.querySelectorAll(".custom__select")) {
if (!select.contains(e.target)) {
select.classList.remove("open");
}
}
});

Answer 1

问题在于您的锚点标记。具体来说，将href属性设置为#将导致页面跳到顶部。

来自MDN:

您可以使用href="#top"或空片段(href="#"(链接到当前页面的顶部，如HTML规范中所定义的。

在您的情况下，只需删除href属性。如果要保留键盘导航，请将其设置为"javascript:void(0)"

for (const dropdown of document.querySelectorAll(".custom__select-wrapper:not(.clearFilter)")) {
dropdown.addEventListener("click", function () {
this.querySelector(".custom__select").classList.toggle("open");
});
}
for (const option of document.querySelectorAll(".custom__option")) {
option.addEventListener("click", function () {
if (!this.classList.contains("selected")) {
this.parentNode
.querySelector(".custom__option.selected")
.classList.remove("selected");
this.classList.add("selected");
this.closest(".custom__select").querySelector(
".custom__select-trigger h6"
).textContent = this.textContent;
if (this.getAttribute("data-type")) {
current_story = this.dataset["type"];
}
}
});
}
window.addEventListener("click", function (e) {
for (const select of document.querySelectorAll(".custom__select")) {
if (!select.contains(e.target)) {
select.classList.remove("open");
