Mobile Angular UI - 滑动手势

Mobile Angular UI 中的手势模块处理触摸、滑动、拖动项目等功能。手势模块具有指令和服务，可以处理触摸、滑动和拖动所需的功能。

要在 Mobile Angular UI 中使用手势功能，需要添加手势模块。

首先，如下所示在 index.html 中添加 JavaScript 文件：

<script src="node_modules/mobile-angular-ui/dist/js/mobile-angular-ui.gestures.min.js"></script>

然后，如下所示在 app.js 中添加手势模块作为依赖项：

var app=angular.module('myFirstApp', [
   'ngRoute',
   'mobile-angular-ui',
   'mobile-angular-ui.gestures'
]);

我们已经讨论过如何使用手势模块实现拖动功能。请查看拖放章节中的相关内容。

这里我们将了解滑动功能。

提供的指令uiSwipeLeft 和 uiSwipeRight 有助于检测用户滑动的方向。

这是一个关于滑动的示例：

以下是浏览器中的显示效果：

滑动指令添加到 home.html 中。

<div class="scrollable-content section"
   ui-swipe-left="testSwipe('left side')"
   ui-swipe-right="testSwipe('right side')">

它调用一个方法 testSwipe()，该方法在 app.js 中定义。

$scope.testSwipe=function(direction) {
   alert('You swiped ' + direction);
};
