如何修复推特引导和弹窗滚动?

I am using twitter-bootstrap and popovers.

我使用的是twitter-bootstrap和弹窗。

I am facing the following problem: when the user clicks on a link that opens a popover at the bottom of the page, it scrolls all the way to top of the page first. This requires the user to scroll back down to see the popover open. In the demos on the twitter-bootstrap site, I don't see this and was wondering if I could get help on this issue.

我面临的问题是:当用户点击打开页面底部弹出窗口的链接时，它首先滚动到页面顶部。这需要用户向下滚动才能看到弹出窗口打开。在twitter-bootstrap网站上的演示中，我没有看到这一点，我想知道能否在这个问题上得到帮助。

<div class="span1" style=" width: 60px; ">
    <a href="#" class="example2" rel="popover" data-html="true" data-placement="left" data-content="&lt;a href = '/social/2lPdXV1KO4s/Bhangra indian Jingle Bells balle balle Merry Christmas'&gt;&lt;img src='http://i4.ytimg.com/vi/2lPdXV1KO4s/hqdefault.jpg'&gt;&lt;/a&gt;" data-original-title="Bhangra indian Jingle Bells balle balle Merry Christmas">
        <img src="http://graph.facebook.com/1236870349/picture">
    </a>

    <div class="popover fade left in" style="top: 831px; left: 805.61669921875px; display: block;">
    <div class="arrow"></div>
    <div class="popover-inner">
        <h3 class="popover-title">Bhangra indian Jingle Bells balle balle Merry Christmas</h3>
        <div class="popover-content">
            <p><a href="/social/2lPdXV1KO4s/Bhangra indian Jingle Bells balle balle Merry Christmas"><img src="http://i4.ytimg.com/vi/2lPdXV1KO4s/hqdefault.jpg"></a></p>
        </div>
    </div>
</div>

It seem like you now have to prevent the default behavior of the link because they added the option to popup the popover on hover/focus. Right now the link will activate and since the href is pointing to "#" it will bring you to the top of the page. Before in older versions, it used to prevent this default automatically.

看起来您现在必须防止链接的默认行为，因为他们添加了在鼠标悬停/焦点上弹出窗口的选项。现在链接将被激活，由于href指向“#”，它将把你带到页面的顶部。在以前的版本中，它会自动地防止这个默认值。

Your javascript code should look something like this:

您的javascript代码应该如下所示:

<script>
$("a[rel=popover]")
    .popover()
    .click(function(e) {
        e.preventDefault();
     });
 </script>

With html like this

与html这样的

<a href="#" 
   class="btn btn-large btn-danger" 
   rel="popover" 
   data-content="And here's some amazing content. It's very engaging. right?" 
   data-original-title="A Title">
     Click to toggle popover
 </a>

Here is a working JSfiddle. http://jsfiddle.net/hajpoj/KPU47/7/

这是一个工作的JSfiddle。http://jsfiddle.net/hajpoj/KPU47/7/

Edit: Alternatively you could use a div instead of a anchor tag and not have to do the whole prevent default thing.

编辑:也可以使用div而不是锚标记，而不必执行整个“防止”默认设置。

<div 
   class="btn btn-large btn-danger popover-link"
   data-content="And here's some amazing content. It's very engaging. right?"
   data-original-title="A Title">Click to toggle popover
</div>

<script>
    $(".popover-link").popover();
</script>

I have encountered exactly the same issue with the popover and it was enough to replace href="#" with href="javascript://".

我在弹窗中遇到了同样的问题，用href="javascript://"替换href="#"就足够了。

Just use this code. No extra div, class or whatever else needed.

只使用这段代码。没有额外的div，类或任何其他需要。

$("a[data-toggle=popover]").popover().click(function(e) {
        e.preventDefault();
});

Very similar to what @hajpoj said, except it's the order that matters. As well, this is a nicer way to do it because you can dynamically add .popover elements to the page and it will continue to work.

和@hajpoj说的很相似，只是顺序很重要。此外，这是一种更好的方式，因为您可以动态地向页面添加.popover元素，它将继续工作。

$('body').on('click', 'a[rel=popover]', function(e) {
  e.preventDefault();
  return;
}).popover({
  selector: 'a[rel=popover]'
});

add onclick="return false;" to your link; it prevents the browser from following the "#" link:

将onclick="return false "添加到您的链接;它阻止浏览器跟随“#”链接:
