单击链接时删除的菜单

Question

我希望当窗口为768px 或更少时，如果我单击其中一个链接，它会将我带到正确的位置。目前，它只会关闭，但菜单保持打开状态，十字保持激活状态。

我用 each 添加了最后一部分，但它不能正常工作，并且当我单击链接时菜单会消失，并且在窗口大于 768px 的情况下。

$(document).ready(function() {
  resize()
});

function resize() {
  if (window.innerWidth >= 768) {
    $('.nav__menu').addClass('is-open');
  } else if ($('.nav__menu').hasClass('is-open')) {
    $('.nav__menu').removeClass('is-open');
  }

}

$(window).on('resize', function() {
  resize()
});

$('.nav__burger').on('click', function() {
  if ($(this).hasClass('is-active')) {
    $(this).removeClass('is-active');
    $('.nav__menu').removeClass('is-open');
  } else {
    $('.nav__menu').addClass('is-open');
    $(this).addClass('is-active');
  }
});

$('.menu-item').each(function() {
  $(this).click(function() {
    $('.nav__menu').removeClass('is-open')
    $('.nav__burger').removeClass('is-active');
  })
});

Answer 1

您可以检查屏幕上的innerWidth，看看它是否超过>= 768，然后是return false，不要做任何事情或else，您可以从您的菜单项中查看addClass 和removeClass。

添加这个code：

$('.menu-item').click(function() {
  if (window.innerWidth >= 768) {
    return false
  } else {
    $('.nav__menu').removeClass('is-open')
    $('.nav__burger').removeClass('is-active');
  }
})

Answer 2

你的 CSS 中缺少 is-open 类。

.header .is-open {
    opacity: 1;
}

此外，您还需要按以下方式更改调整大小功能

function resize() {
    if (window.innerWidth >= 768) {
        $('.nav__menu').addClass('is-open');
        $('.nav__burger').addClass('is-active');
    } else if ($('.nav__menu').hasClass('is-open')) {
        $('.nav__menu').removeClass('is-open');
    }
}

因此，如果windoe >= 768，则导航汉堡处于活动状态。
