这是我试过的。我已经在 span 中给出了这个标签。但是，它没有在导航栏中显示图标。

 <i class="ion-navicon" style="font-size:32px; vertical-align:-6px;"></i>

index.html

最佳答案

OnsenUI 正在使用 Ionicons .因此，为了使其显示，您需要添加 ionicons.css文件到你的元素中。有两种方法:

  1. 在本地包含文件。去here .然后，点击Download按钮。提取文件并添加 ionicons.css文件到你的元素中。确保在您的元素中遵循以下文件夹安排:<link rel="stylesheet" type="text/css" href="ionicons/css/ionicons.css"> .否则，图标仍然不会显示。
  2. 使用 CDN url 自动包含文件。在您的 html header 中添加此链接: <link rel="stylesheet" type="text/css" href="http://code.ionicframework.com/ionicons/1.5.2/css/ionicons.min.css">

注意:我测试过，网站上当前的 CDN url 似乎不起作用。因此，现在请按照步骤 1 中所示手动添加文件。我还将此事通知了 OnsenUI 团队。他们表示将更新网站并告知用户这一要求。
