另一种可能的解决方案是在用户单击按钮时使用Javascript侦听器添加类，然后使用另一个侦听器集中删除该类。这保持了可访问性(可见的标签)，同时也防止了Chrome的奇怪行为，认为一个按钮在点击时集中。

JS:

$('button').click(function(){
    $(this).addClass('clicked');
});
$('button').focus(function(){
    $(this).removeClass('clicked');
});

CSS:

button:focus {
    outline: 1px dotted #000;
}
button.clicked {
    outline: none;
}

我有同样的问题使用<a>作为按钮，我发现我错过了一个工作区添加attr类型=“按钮”使它的行为正常为我至少。

<a type=“巴顿”类=“bmr btn-primary”>释放我!< / a >

这是工作，希望能帮到你

.btn:focus, .btn:focus:active {
    outline: none;
}

我找到了解决办法。 当我们聚焦时，bootstrap使用box-shadow，所以我们只是禁用它(声誉不够，无法上传图像:)。

我添加

.btn:focus{
    box-shadow:none !important;
}

它的工作原理。

I found the same situation using a submit button in a form using a bootstrap (v4.4.1) class. The problem arose as I was building a single-page user interface using JavaScript to manipulate all the required changes to the DOM. The form data was submitted to the server via 'fetch' using a JSON string rather than a HTTP POST request. Note that usually the form's default behaviour is to reload the document, and normally this would refresh the button, however the form's default behaviour was prevented by using e.preventDefault() in the listener function for the form's submit event (it is a single-page UI so the document is never reloaded and traffic to the server is minimised to data only). Given the document was not reloaded the button appeared to stay depressed until the user clicked elsewhere in the window. This is what I had (with the problem):

<输入类型=“submit”类=“btn btn-primary”>

这是我用来解决按钮一直按下的问题:

<input type=“submit” class=“btn btn-primary” onmouseup=“this.blur（）”>
