javascript - Javascript选中复选框结果？

Question

我正在练习看起来像这样的javascript代码，

Now I want to keep the first checked result when more than two checkboxes are selected.

请给一些反馈。

谢谢

const pdItem = document.querySelectorAll(".shopbox");

document.querySelector(".item-container").addEventListener("click", (event) => {
  const filterClass = event.target.dataset["name"];
  pdItem.forEach((elem) => {
    if (filterClass !== null && !elem.classList.contains(filterClass)) {
      elem.classList.add("hide");
    } else {
      elem.classList.remove("hide");
    }
  });
});
