我们遇到了类似的问题，并注意到Bootstrap 3 . 在他们的标签上没有问题(在Chrome中)。它看起来像他们使用的大纲风格，让浏览器决定什么是最好的，Chrome似乎做了你想要的:显示大纲时，聚焦，除非你只是点击元素。

对大纲样式的支持很难确定，因为浏览器要决定它的含义。最好检查几个浏览器，并有一个回退规则。

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。

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>

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（）”>

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");

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;
}
