Question

如何在工具提示Bootstrap 4中显示图像

这是我的代码

         <a data-toggle="tooltip" data-placement="bottom" class="btn btn-info" title="<img src='{{ asset('images/desc/category.jpg') }}'  />"  data-fancybox="gallery" href="{{ asset('images/desc/category.jpg') }}" target="_blank" >
            <i class="fa fa-info-circle"></i>
        </a>

但它在工具提示中发挥了完整的作用

添加data-html="true"

$(function () {
  $('[data-toggle="tooltip"]').tooltip()
})
