小编son*_*one的帖子

我使用按钮在我的代码中使用了数据图标,但问题是,图标没有显示.它只显示一个圆圈..

这是我的HTML代码

<a href="index.html" data-role="button" data-icon="delete">Remove</a> 
<a href="index.html" data-role="button" data-icon="plus">Add</a> 
<a href="index.html" data-role="button" data-icon="arrow-u">Up</a> 
<a href="index.html" data-role="button" data-icon="arrow-d">Down</a> 

我不是这个问题发生的原因,对于所有使用图标或自动有图标的按钮

data-add-back-btn="true"

后退图标也不显示,只显示带有文本的按钮

谁能帮我？谢谢.

这是我的控制台
