如果你想在鼠标下而不是键盘标签上完成轮廓的删除，并且你正在使用VueJS，下面是解决方案:

<button @mousedown="$event.preventDefault()">No Online On Click</button>

这基本上阻止它在点击时接收焦点，但任何其他接收焦点的方式都保持活跃。

这是工作，希望能帮到你

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

这对我来说是可行的，另一个没有提到的解决方案。只要把它扔在点击事件…

$(this).trigger("blur");

或者从另一个事件/方法调用它…

$(".btn_name").trigger("blur");

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（）”>

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

  .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
