我使用 bootstrap 创建了一组按钮:
如图所示，我已将“欧洲”按钮设为默认激活状态。如果我单击其他按钮，事件按钮将切换，因此效果很好。但是，如果我有一个激活的按钮，然后单击页面上的其他地方(不是按钮)，它也会停用当前按钮。如何使按钮保持事件状态，直到单击另一个按钮？

最佳答案
在 bootstrap 4 中你可以使用 btn-group-toggle:
<div class="btn-group btn-group-toggle" data-toggle="buttons">
<label class="btn btn-secondary active">
<input type="radio" name="options" id="option1" autocomplete="off" checked> Active
</label>
<label class="btn btn-secondary">
<input type="radio" name="options" id="option2" autocomplete="off"> Radio
</label>
<label class="btn btn-secondary">
<input type="radio" name="options" id="option3" autocomplete="off"> Radio
</label>
</div>
这应该可以解决您的问题，因为它将像复选框一样使用此按钮。
