当我点击屏幕上的其他地方时，按钮的底部边框消失 [英] Button's bottom border disappears when i click somewhere else on the screen

问题描述

小提琴

这是我的HTML代码：

This is my HTML code:

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.5.0/css/font-awesome.min.css">
<button>
    <i class="fa fa-5x fa-motorcycle gobumpr_icon"></i>
</button>
<button>
    <i class="fa fa-car fa-5x gobumpr_icon"></i>
</button>

这是我的CSS：

button:focus {
    border-bottom: thick solid #FFA800;
    border-bottom-left-radius: 5px;
    border-bottom-right-radius: 5px;
    transition: width 2s;
    -webkit-transition: width 2s;
    outline: none;
    box-shadow: none;
}

我想让边框底部停留，直到另一个按钮被点击。

I want that border bottom to stay until the other button is being clicked. How can I do that?

推荐答案

：focus 不会帮助，因为边框将删除，每当你会点击外面。为此，您需要在上添加一个类，单击按钮，除非点击同一页面中的其他按钮，否则将保留。

:focus is not going to help because border will remove whenever you will click outside. For this you need to add a class on click of button that will stay unless another buttons inside the same page is clicked.

$(function() {
   var buttons = $('.button');
  
   buttons.click(function(e) {
     e.preventDefault();

     buttons.removeClass('focus');
     $(this).addClass('focus');
  });
});

.button.focus {
  border-bottom:thick solid #FFA800;
  border-bottom-left-radius: 5px;
  border-bottom-right-radius: 5px;
  transition: width 2s;
  -webkit-transition: width 2s;
  outline:none;
  box-shadow:none;    
}
