如何在 lightGallery 中动态更改图像 url

Question

我有一个问题，我的图像在每个 click 不同的图像

中都没有改变

问题：

改变不同的图像它没有改变
预览图像总是显示相同的图像

问题：我想为每个图像更改图像预览

此处演示： https://codepen.io/eabangalore/pen/OrWaRz

$(document).ready(function() {
  $('#dynamic li').on('click', function(e) {
     var imgUrl = $(this).find('img').attr('data-src');
     $('.image-wrapper img').attr('src',imgUrl);
  });
  $('.image-wrapper').on('click',function(){
     var imgUrl = $(this).find('img').attr('src');
      $(this).lightGallery({
          dynamic: true,
          dynamicEl: [{
              src: imgUrl,
              thumb: imgUrl
          }]
      });
   });
});

Answer 1

在文档中，它说您必须 destroy() the current gallery and create it again if you want to refresh the content, reference to the previous indications is here。即使这样做，库仍然存在一些问题，所以我设法让它工作，在销毁前一个库和创建新库之间添加 250ms 的延迟。

示例：

$(document).ready(function()
{
    $('#dynamic li').on('click', function(e)
    {
        var imgUrl = $(this).find('img').attr('data-src');
        $('.image-wrapper img').attr('src', imgUrl);
    });

    $('.image-wrapper').on('click', function()
    {
        var imgUrl = $(this).find('img').attr('src');

        // Destroy previous gallery.
        
        if ($(this).data('lightGallery'))
            $(this).data('lightGallery').destroy(true);

        // Wait some time before create the new gallery.
 
        var target = $(this);

        setTimeout(function()
        {
            target.lightGallery({
                dynamic: true,
                dynamicEl: [{src: imgUrl, thumb: imgUrl}]
            });
        }, 250);
    });
});
