Question

我开发了一个灯箱功能，大部分都是用CSS制作的。虽然它一目了然，但我一直面临一些复杂的问题，它通过锚链接打开和关闭，主要问题是它增加了浏览器历史记录的条目。

以下是我所指的一个例子：

我在页面上加载了应用了灯箱功能的图片。
我点击图片，灯箱窗口打开。
然后我关闭灯箱窗口，然后返回页面;但是，通过锚链接行为（通过http://SITEURL.com/PAGEURL#theanchor附加页面的URL）来打开和关闭灯箱，现在添加了2个额外的历史条目。

从之前的响应者判断，链接到锚点似乎是产生此类功能的最少建议。如果是这种情况，我怎么能实现这一点，（并且我可能完全避免使用锚点）？

这是一个完整的代码段，用于显示正在运行的灯箱功能以及锚链接行为：

$('.pic > img').click(function() {
  var srcToCopy = $(this).attr('src');
  $('body').find('.imgsrc').attr('src', srcToCopy);
  $('body').addClass('no-scroll');
});

$('#customlightbox-controls').on('click', function() {
  $('body').removeClass('no-scroll');
});

body {
  margin: 0;

  width: 100%;

  overflow: hidden;

我不小心发布了这个答案，但你可以删除锚标签，只需添加光标：指针; css到你的.pic课程。

exports.redirectFunc = function redirectFunc (req, res) {
  res.set('Location', 'https://example.com/destination');
  res.status(302);
  res.end();
};

$('.pic > img').click(function() {
  var srcToCopy = $(this).attr('src');
  $('body').find('.imgsrc').attr('src', srcToCopy);
  $('body').addClass('no-scroll');
});

$('#customlightbox-controls').on('click', function() {
  $('body').removeClass('no-scroll');
});

body {
  margin: 0;
  padding: 0;
  border: 0;
  height: 100%;
  width: 100%;
}

body.no-scroll {
  overflow: hidden;
}

.pic,

  display: inline-block;

Answer 2

您可以阻止默认操作，而不是将哈希添加到网址（或历史记录）

$('a[href^="#"]').click(function(evt){
   evt.preventDefault()
});

我使用Lightbox已经很长时间了，不确定这是否会与它的功能发生冲突

是否有替代方法来替换这些锚链接？
