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)
