单击后按钮保持焦点（悬停）

Question

我正在使用bootstrap和vue 2.0。

当我不单击按钮时，它可以正常工作。像这样，它专注于@mouseenter而不关注@mouseleave。

但是当我单击按钮时，它会像这样一直保持焦点，直到我在任何地方（即使在另一个窗口中）再次单击。

我该如何解决？这是HTML和CSS代码。

按钮html：

 <button class="btn btn-primary" v-on:click="search()"
                          type="button">{{$lang.ticketsSearch}}</button>

按钮CSS：

.btn {
  display: inline-block;
  padding: 6px 12px;
  margin-bottom: 0;
  font-size: 14px;
  font-weight: normal;
  line-height: 1.42857143;

单击该按钮时，它将进入：focus状态。如果您不希望它具有这种行为，则必须覆盖焦点状态，但这可能不是一个好主意。您可以通过编程方式将重点放在其他方面。

在这种特殊情况下，当您单击并移开时要删除“绿色”，您只需要执行以下操作：

.btn-primary:focus,
.btn-primary.focus {
  color: #fff;
  background-color: #000; /*this is where the colour was green*/
  border-color: #122b40;
}
