Bootstrap Glyphicon 弹出框

Question

我想知道为什么下面的字形图标不会触发悬停弹出窗口.. 可以请教吗？

<div class="form-group has-feedback">
    @Html.LabelFor(model => model.FullName, htmlAttributes: new { @class = "control-label col-md-2" })
    <div class="col-md-10 ">
       @Html.EditorFor(model => model.FullName, new { htmlAttributes = new { @class = "form-control" } })
       <span class="glyphicon glyphicon-question-sign form-control-feedback" rel="popover" data-trigger="hover"  data-toggle="popover" data-placement="bottom" title="Title" data-content="Content"></span>
       @Html.ValidationMessageFor(model => model.FullName, "", new { @class = "text-danger" })
    </div>

Answer 1

删除类， form-control-feedback，来自<span> 元素
