Bootstrap 3按钮组:在隐藏按钮后,角落半径消失 [英] Bootstrap 3 button group: corner radius disappears after a button is hidden
问题描述
我有以下Bootstrap 3按钮组:
< div class =btn-group>
< button type =buttonclass =btn btn-default>向左< /按钮>
< button type =buttonclass =btn btn-default>中间< /按钮>
< button type =buttonclass =btn btn-default> Right< / button>
< / div>
我隐藏第一个按钮:
<$ 。p $ p> $( 按钮:当量(0))隐藏();
结果是第一个可见按钮没有角半径:
我猜BS说: .btn-group的第一个孩子有边界半径而不是第一个可见 .btn-group的孩子有边界半径
有什么方法可以解决这个问题?
请注意,我不想删除按钮,但要隐藏它。
鉴于您已经使用jQuery,您可以使用以下内容将一个类添加到第一个/最后一个可见按钮元素中。
$(。btn )
.first()
.addClass('radius-left')
.end()
.last()
.addClass (半径右);
$然后您需要添加以下样式: b
.btn-group> .btn.btn-default.radius-left {
border-top-left-radius:4px!important;
border-bottom-left-radius:4px!important;
}
.btn-group> .btn.btn-default.radius-right {
border-right-right-radius:4px!important;
border-bottom-right-radius:4px!important;
}
不幸的是,!important
是必要的,以覆盖默认的引导样式。
另外,您可以完全移除第一个按钮元素,然后在需要时将其添加回来。 $(button:eq(0))。remove();
- (示例)
I have the following Bootstrap 3 button group:
<div class="btn-group">
<button type="button" class="btn btn-default">Left</button>
<button type="button" class="btn btn-default">Middle</button>
<button type="button" class="btn btn-default">Right</button>
</div>
I hide the first button using:
$("button:eq(0)").hide();
The result is that the first visible button doesn't have corner radius:
I guess the BS says: first child of .btn-group has border-radius instead of first visible child of .btn-group has border-radius
Is there any way to fix this?
Note that I don't want to remove the button but to hide it.
Given that you are already using jQuery, you could use the following to add a class to the first/last visible button elements.
$(".btn-group button:visible")
.first()
.addClass('radius-left')
.end()
.last()
.addClass('radius-right');
You would then need to add the following styling:
.btn-group > .btn.btn-default.radius-left {
border-top-left-radius: 4px!important;
border-bottom-left-radius: 4px!important;
}
.btn-group > .btn.btn-default.radius-right {
border-top-right-radius: 4px!important;
border-bottom-right-radius: 4px!important;
}
Unfortunately, !important
is necessary to overwrite the default Bootstrap styling.
As an alternative, you could remove the first button element completely and then add it back in when necessary.. $("button:eq(0)").remove();
