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。

如果您正在使用webkit浏览器(可能是与webkit供应商前缀兼容的浏览器)，则该轮廓属于按钮的-webkit-focus-ring伪类。简单地设置它的轮廓为none:

*:-webkit-focus-ring {
  outline: none;
}

Chrome就是这样一个webkit浏览器，这种效果也会发生在Linux上(不仅仅是macOS的事情，尽管一些Chrome风格只适用于macOS)

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>

将此添加到脚本中

$(document).ready(function() {
    $('#addBtn').focus(function() {
        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");
