Bootstrap Glyphicon Popover

Question

我想知道为什么下面的图形不会触发悬停弹出窗口.. 您能否提供建议？

<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，从<span>元素
