Javascript Bookmarklet - 在页面上打开多个链接

Question

我想制作一个小书签，这样当我进入 Digg 时，我只需单击它即可在新选项卡中打开前 10 篇故事。

页面上的 HTML 如下所示：

<div id="topten-list">
  <div class="news-summary img-thumb">

</div>

因此，在每个具有“news-summary”类的 div 中，都有一个链接。我怎样才能让javascript浏览div“topten-list”并打开每一个？

Answer 1

我更喜欢使用 jQuery

，但要在外部站点上应用它，请尝试这个（提示我从上一个线程复制粘贴）
我建议创建一个包含两个 iframe 的页面，一个用于导航到指定网站，另一个用于获取 DOM 对象。
在第一个导航到该站点，然后选择其 HTML 并
将其附加到第二个 Iframe 的正文中。

iframe2.contentWindow.document.body.innerHTML = iframe1.contentWindow.document.body.innerHTML

然后在第二个 iframe 中，您将加载 jquery 脚本，并且可以运行此代码。

$("news-summary img-thumb").find("news-digg").find("a").each(
function()
{
window.open(window.location + $(this).attr("href"));
}
)

告诉我进展如何

Answer 2

解决方案是这样的：我创建了一个 Javascript for 语句，该语句循环遍历 topten-list div 并选择所有名为“a”的标签。

最后的书签是这样的：

javascript:for(i=0;i<=18;i=i+2){window.open(document.getElementById('topten-list').getElementsByTagName('a')[i]);}

Ta-da！
