我在引导选项卡中集成了一个浮动按钮。第一个选项卡工作正常，但对于第二个选项卡，按钮在向下滚动到底部时闪烁。您可以在此处查看测试 html

当您在第一个选项卡中时，您的 html div 看起来像： 

<div class="float_bottom_div_s2 subnav-editprofile-sticky-bar-bottom"> 
    <input type="submit" class="float_button button" value="Submit">
</div>

当您单击第二个选项卡时，您的 html 就像变成： 

<div class="float_bottom_div_s2 edit_profile_save_pre subnav-editprofile-sticky-bar-bottom"> 
    <input type="submit" class="float_button button" value="Submit">
</div>

因此，当您单击第二个选项卡时，不应添加属性“edit_profile_save_pre” 。
