迟到了，但谁知道这也许能帮到谁呢。 CSS看起来像这样:

.rhighlight{
   outline: none !important;
   box-shadow:none
}

HTML看起来像这样:

<button type="button" class="btn btn-primary rHighlight">Text</button> 

这样你就可以保留btn和它相关的行为。

这是工作，希望能帮到你

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

您可以使用按钮的焦点事件。 这适用于angular的情况

<button (focus)=false >Click</button

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（）”>

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。
