Question

我想浏览id为'imgDiv'的div的所有子元素，并用一个用父锚包装图像创建的新元素替换所有子元素。与<image src=...>到<a href=...><image ...></a>一样。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，我认为这是由每个函数引起的吗？

Answer 1

你试图用附加它的元素替换this，并通过附加一个元素，实际上移动它，因此，在这里，将它从DOM中删除，因此错误

替换

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

与

$(this).wrap(fancyAnchor);

Answer 2

不要使用$（this）.replace或更改每个内部的DOM。

编辑：似乎不是问题

＆GT;

我还建议使用$ .each（...，f）代替$（...）。每个（f）。

你也应该考虑wrap function而不是$ .each，它完全符合你的需要：

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

jQuery replaceWith期间的HierarchyRequestError
