Question

我有一些这种格式的HTML：

<div id="logos" class="downloadlist">
    <ul>
        <li><a href="/toolkit/logos/download.jpg" data-image="images/toolkit/logos/one.jpg">First Logo</a></li>
        <li><a href="/toolkit/logos/download.jpg" data-image="images/toolkit/logos/two.jpg">Second Logo</a></li>
        <li><a href="/toolkit/logos/download.jpg" data-image="images/toolkit/logos/three.jpg">Third Logo</a></li>
    </ul>
</div>

我想逐步完成并将其提供给Fancybox like this。

我已经达到了这个目标，但它是直接的，不起作用：

downloadList = $('#logos ul li a');

var downloadArray = {};

downloadJSON = '';

$.each(downloadList, function(d)
{
    var download = $(this);
    var href = download.data('image');
    var title = download[0].innerText;
    var link = download[0].href;

    downloadArray[d] = {};
    downloadArray[d].href = href;
    downloadArray[d].title = "<a href=\'" + link + "\'>"+title+"</a>";

    downloadJSON += JSON.stringify(downloadArray[d])+',';
});

downloadJSON = downloadJSON.slice(0, -1);

$.fancybox.open([downloadArray]);

downloadJSON给了我：

{"href":"images/toolkit/logos/one.jpg","title":"<a href='http://example.com/toolkit/logos/download.jpg'>First Logo</a>"},{"href":"images/toolkit/logos/two.jpg","title":"<a href='http://example.com/toolkit/logos/download.jpg'>Second Logo</a>"},{"href":"images/toolkit/logos/three.jpg","title":"<a href='http://example.com/toolkit/logos/download.jpg'>Third Logo</a>"}

对downloadArray对象的JSON.stringify给了我：

{"0":{"href":"images/toolkit/logos/one.jpg","title":"<a href='http://example.com/toolkit/logos/download.jpg'>First Logo</a>"},"1":{"href":"images/toolkit/logos/two.jpg","title":"<a href='http://example.com/toolkit/logos/download.jpg'>Second Logo</a>"},"2":{"href":"images/toolkit/logos/three.jpg","title":"<a href='http://example.com/toolkit/logos/download.jpg'>Third Logo</a>"}}

任何帮助都将不胜感激。

Answer 1

links = [];
$('#logos ul li a').each(function() {
   links.push({
      href: $(this).attr('data-image'),
      title: "<a href=\'" + $(this).attr('href') + "\'>"+$(this).html()+"</a>"
   });
});
//JSON.stringify(links);
$.fancybox.open(links);

Answer 2

我的答案基于@Adrian的回答：

为了根据所选链接下载（在fancybox中显示）正确的徽标，我们使用API选项index，如下面的调整扩展代码：

links = [];
$('#logos ul li a').each(function (indx) {
  // Adrain's code tweaked
  links.push({
    href: $(this).data('image'),
    title: "<a href=\'" + $(this).data('image') + "\'>" + $(this).html() + "</a>"
  });
  // extended to catch click on links
  $(this).on("click", function (e) {
    e.preventDefault();
    $.fancybox.open(links, {
      index: indx // starts gallery with index of the clicked link
    });
  });
});
//JSON.stringify(links);
//$.fancybox.open(links); // would open fancybox on page load

如何让jQuery Fancybox接受我的对象作为有效的开放参数？
