jquery - 如何使用 twitter-bootstrap 和 popover 修复滚动？

Question

我正在使用 twitter-bootstrap 和弹出框。

我面临以下问题：当用户单击在页面底部打开弹出窗口的链接时，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框打开。在 twitter-bootstrap 站点上的演示中，我没有看到这一点，我想知道是否可以就这个问题获得帮助。

<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>

Answer 1

看起来您现在必须阻止链接的默认行为，因为他们添加了在悬停/聚焦时弹出弹出框的选项。现在链接将激活，因为 href 指向“#”，它会将您带到页面顶部。以前在旧版本中，它用于自动阻止此默认设置。

您的 javascript 代码应如下所示：

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

像这样的html

<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>

这是一个有效的 JSfiddle。http://jsfiddle.net/hajpoj/KPU47/7/

编辑：或者，您可以使用 div 而不是锚标记，而不必执行整个阻止默认操作。

<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>

Answer 2

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

Answer 3

只需使用此代码。没有额外的div，class或任何其他需要。

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

Answer 4

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

Answer 5

与@hajpoj 所说的非常相似，只是顺序很重要。同样，这是一种更好的方法，因为您可以动态地将.popover元素添加到页面，并且它将继续工作。

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