描述 (Description)
Preloader模式定义后台操作并在此操作期间停止用户操作。 它使用以下方法打开预加载器模式 -
myApp.showPreloader([title])
title - 这是一个可选方法,用于显示带有标题的预加载器模态。
例子 (Example)
以下示例演示了Framework7中预加载器模式的使用,它表示加载模式时的一些后台活动 -

<meta name = "apple-mobile-web-app-capable" content = "yes" />
<meta name = "apple-mobile-web-app-status-bar-style" content = "black" />
