问题描述
将Bootstrap升级到4.2.1版本后出现问题.在此版本中,当我在accordion
中使用id="#12"
时,它不起作用.在以前的版本中,它可以与id="#12"
一起使用.有什么想法吗?
I have problems after upgrading Bootstrap to 4.2.1 version. In this version when I use id="#12"
in accordion
it's not working. In previous versions it worked fine with id="#12"
. Any ideas?
<div id="accordion">
<div class="card">
<div class="card-header" id="headingOne">
<h5 class="mb-0">
<button class="btn btn-link" data-toggle="collapse" data-target="#12"
aria-expanded="true" aria-controls="collapseOne">
Collapsible Group Item #1
</button>
</h5>
</div>
<div id="12" class="collapse show" aria-labelledby="headingOne" data-parent="#accordion">
<div class="card-body">

推荐答案
在HTML 5中,以数字开头的ID是有效的,但是CSS不允许前导数字.
While in HTML 5, it is valid to start an id with a numeric, CSS doesn't allow leading numerics.
内部,Bootstrap 4正在使用
Internally, Bootstrap 4 is using
getSelectorFromElement(element) {
let selector = element.getAttribute('data-target')
if (!selector || selector === '#') {
const hrefAttr = element.getAttribute('href')
selector = hrefAttr && hrefAttr !== '#' ? hrefAttr.trim() : ''
}
try {
return document.querySelector(selector) ? selector : null
} catch (err) {
return null
}
}
查找您的元素. querySelector
需要一个有效的CSS选择器
To lookup your element. querySelector
requires a valid CSS selector
我建议仅使用有效的CSS标识符.您还可以采取一些技巧来逃脱,但除非必须这样做,否则只需使用其他选择器即可.
I'd recommend just using a valid CSS identifier. There's also tricks you can do to escape, but unless if you have to, just use a different selector
