Mobile Angular UI - 滑动手势
触摸、滑动、拖动项目等功能由 Mobile Angular UI 中的手势模块处理。手势模块有一个指令和服务来处理触摸、滑动和拖动所需的功能。
要使用 Mobile Angular UI 中的手势功能，您需要添加手势模块。
首先在 index.html 中添加 JavaScript 文件，如下所示 −
<script src="node_modules/mobile-angular-ui/dist/js/mobile-angular-ui.gestures.min.js"></script>
稍后在 app.js 中添加手势模块作为依赖项，如下所示−
var app=angular.module('myFirstApp', [
'ngRoute',
'mobile-angular-ui',
'mobile-angular-ui.gestures'
]);
我们已经讨论了如何使用手势模块来实现拖动功能。请查看拖放章节。
这里将介绍滑动功能。
指令uiSwipeLeft和uiSwipeRight有助于检测用户滑动的方向。
以下是有关滑动的一个工作示例 −

以下是浏览器中的显示 −
滑动指令已添加到 home.html 中。
<div class="scrollable-content section"
ui-swipe-left="testSwipe('left side')"

它调用方法 testSwipe()，它在 app.js 中定义。
$scope.testSwipe=function(direction) {
alert('You swiped ' + direction);
};
