form-control-feedback
似乎不是引导程序4的一部分。使用引导程序4来获得以下结果(文本框中的图标)的最佳方法是什么?

您可以只使用css类并应用它(请注意v4 cdn),但要减去固定的大小调整约定,例如;
.form-control-feedback {
position: absolute;
top: .5rem;
right: 1.5rem;
z-index: 2;
display: block;
text-align: center;
pointer-events: none;
}

<div class="container">
<form class="form-horizontal">
<div class="form-group has-warning has-feedback">
<div class="col-sm-10">
<input type="text" class="form-control">
<span class="form-control-feedback"><i class="fa fa-rotate-right"></i></span>
</div>
</div>
</form>
</div>
</body>
但是,请注意,如果进入并使用用于输入大小设置的sass设置等,则需要相应地调整top
和right
的值以及可能添加的字体大小。 / p>
