我想遍历 id 为“imgDiv”的 div 的所有子元素,并将它们全部替换为通过用父锚点包装图像创建的新元素。喜欢。<image src=...>_ <a href=...><image ...></a>代码如下:

$(document).ready(function(){
    var elem = $('.imgDiv');
    $(elem).children('.image').each(function(){
            var src = $(this).attr('src');//get the src of a image
            console.log(src);
            var fancyAnchor = $(document.createElement('a')).addClass('fancybox');//create an anchor parent of this image
            //add some attr to meet the need of the lib
            fancyAnchor.attr('data-fancybox-group', 'gallery');
            fancyAnchor.attr('href', src);
            //append this to the anchor
            fancyAnchor.append(this);
            //replace this with the new created anchor <a>
            $(this).replaceWith(fancyAnchor);
        });
  });  

错误很奇怪,我认为这是由每个功能引起的吗?

您试图用this您附加它的元素替换,并且通过附加一个元素,您实际上是移动了它,因此,在这里,将它从 DOM 中删除,因此出现错误。

代替

fancyAnchor.append(this);
$(this).replaceWith(fancyAnchor);

$(this).wrap(fancyAnchor);

不要使用 $(this).replace 或任何改变每个内部 DOM 的东西。

编辑:似乎这不是问题

我还建议使用 $.each(...,f) 而不是 $(...).each(f)。

您还应该考虑使用wrap 函数而不是 $.each,它完全符合您的需要:

$(elem).children('.image').wrap(function(){
            return $('<a>').addClass('fancybox').attr('data-fancybox-group', 'gallery').attr('href', $(this).attr('src'));
        });
