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 >

你想要的是:

<button class="btn btn-primary btn-block" onclick="this.blur();">...

.blur()方法正确地删除了焦点高亮显示，并且不会弄乱bootstrap的样式。

我在上面的评论中提到了这一点，但为了清晰起见，有必要把它作为一个单独的答案列出。只要你不需要在按钮上设置焦点，你可以在它应用任何CSS效果之前使用焦点事件删除它:

$('buttonSelector').focus(function(event) {
    event.target.blur();
});

这避免了在使用click事件时可以看到的闪烁。这确实限制了界面，并且您将无法选择按钮，但这在所有应用程序中都不是问题。

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（）”>

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。

如果你不想要按钮的轮廓和所有的状态，你可以用下面的代码覆盖css

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