在HTML表格中切换子菜单列表。

Question

关于切换子菜单项目，似乎有多个问题答案。

jQuery切换子菜单

基于jQuery切换的子菜单可以切换所有子菜单。

然而，我正试图在一个HTML中创建子菜单项目。table.

在页面加载时，我想让子菜单项目显示为打开，就像这样。

你可以通过点击子菜单中的任意位置来切换子菜单，使其变成 "关闭"。<tr> 附带 close-submenu 类（用于测试5或测试6）。

我试着把子菜单项目（行和表数据）放在divs里，但是我的jQuery没有工作。事实上，如果我把divs设置为 display: none但它们仍然在显示。

所以我想知道--是否可以在HTML表格中实现切换功能？

这是我试过的方法。

function submenuClose() {
  $(document)
    .on('click', '.close-submenu', function () {
      $(this).closest('.submenu-list-container').removeClass('active');
    })
}

submenuClose();

这里是一个... 链接到JSFiddle. 正如你所看到的，子菜单的divs无论是否显示在 active 或不。

Answer 1

我看到你是在与HTML语义的冲突:)，所以我把它固定下来。以下是我的解决方案。

const buttons = document.querySelectorAll('[data-submenu]');

buttons.forEach(button => {
  button.addEventListener('click', e => {
    const getSubmenuNumber = e.currentTarget.hasAttribute('data-submenu') ? e.currentTarget.getAttribute('data-submenu') : '';
    const numbers = document.querySelectorAll(`[data-submenu-element="${getSubmenuNumber}"]`);

    numbers.forEach(number => {
      number.classList.toggle('active');
    })
  })
})
