我的按钮都有一个高亮后，我点击他们。这是Chrome。
<button class="btn btn-primary btn-block">
<span class="icon-plus"></span> Add Page
</button>
我正在使用带有主题的Bootstrap，但我非常确定这不是它:我以前在另一个项目中注意到这一点。
如果我使用<a>标签而不是<button>，它就会消失。为什么?如果我想使用<button>，我怎么让它消失呢?

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;
}

其他回答
.btn:focus,.btn:active, a{
outline: none !important;
box-shadow: none;
}
这个大纲:没有将工作的按钮和标签
风格
.not-focusable:focus {
outline: none;
box-shadow: none;
}
使用
<button class="btn btn-primary not-focusable">My Button</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（）”>
与TS溶液反应
const btnRef = useRef<HTMLButtonElement | null>(null);
const handleOnMouseUp = () => {
btnRef.current?.blur();
};
<button
ref={btnRef}
onClick={handleOnClick}
onMouseUp={handleOnMouseUp}
>
<span className="icon-plus"></span> Add Page
</button>
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
