Bootstrap委托Pop over内容回调触发两次 [英] Bootstrap delegated pop over content callback triggered twice

问题描述

我正在使用Twitter Bootstrap 2.3.2，我正在注册一个popover，只要有一个选择器的td悬停在一起。但是我在控制台内注意到内容回调正在被触发两次。有没有办法防止这种情况发生？

I'm using Twitter Bootstrap 2.3.2 and I'm registering a popover to open whenever a td with a selector is hovered over. However I have noticed within the console that the content callback is being trigger twice. Is there a way to prevent this from happening?

$('#table-data').popover({
    selector: '.td-popover',
    trigger : 'hover',
    content : function () {
        console.log(this, arguments)
        return 'hello';
    }
});

<table id="table-data">
    <tbody>
        <tr>
            <td></td>
            <td class="td-popover"></td>
            <td></td>
            <td class="td-popover"></td>
        </tr>
    </tbody>
</table>

推荐答案

你的代码是正确的，这个问题来自bootstrap本身他们说这是一个有意的行为，而不是一个bug。有关详细信息，请参阅此github问题 https://github.com/twbs/bootstrap/issues/12563

your code is correct, this issue comes from bootstrap itself, they say that it is an intentional behavior and not a bug. see this github issue for more details https://github.com/twbs/bootstrap/issues/12563

它们在Bootstrap 3.2（这是当前的稳定版本）中没有改变这种行为，但我认为他们计划在下一个一（3.2.1）

FYI they didn't change this behavior in Bootstrap 3.2 (which is the current stable release), but I think that they plan to do it in the next one (3.2.1)
