ionic 列表操作 · W3School Ionic 教程

# ionic 列表操作列表是一个应用广泛在几乎所有移动app中的界面元素。ionList 和 ionItem 这两个指令还支持多种多样的交互模式，比如移除其中的某一项，拖动重新排序，滑动编辑等等。 ### 用法 ``` <ion-list> <ion-item ng-repeat="item in items"> Hello, {{item}}! </ion-item> </ion-list> ``` ### 高级用法: 缩略图，删除按钮，重新排序，滑动 ``` <ion-list ng-controller="MyCtrl" show-delete="shouldShowDelete" show-reorder="shouldShowReorder" can-swipe="listCanSwipe"> <ion-item ng-repeat="item in items" class="item-thumbnail-left"> <img ng-src="{{item.img}}"> <h2>{{item.title}}</h2> <p>{{item.description}}</p> <ion-option-button class="button-positive" ng-click="share(item)"> 分享 </ion-option-button> <ion-option-button class="button-info" ng-click="edit(item)"> 编辑 </ion-option-button> <ion-delete-button class="ion-minus-circled" ng-click="items.splice($index, 1)"> </ion-delete-button> <ion-reorder-button class="ion-navicon" on-reorder="reorderItem(item, $fromIndex, $toIndex)"> </ion-reorder-button> </ion-item> </ion-list> ``` ### API `delegate-handle(可选)`：`字符串` 该句柄定义带有`$ionicListDelegate`的列表。 `show-delete(可选)`：`布尔值` 列表项的删除按钮当前是显示还是隐藏。 `show-reorder(可选)`：`布尔值` 列表项的排序按钮当前是显示还是隐藏。 `can-swipe(可选)`：`布尔值` 列表项是否被允许滑动显示选项按钮。默认：true。 ## 实例 ### HTML 代码： ``` <html ng-app="ionicApp"> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no"> <title>Ionic List Directive</title> <link href="http://www.runoob.com/static/ionic/css/ionic.min.css" rel="stylesheet"> <script src="http://www.runoob.com/static/ionic/js/ionic.bundle.min.js"></script> </head> <body ng-controller="MyCtrl"> <ion-header-bar class="bar-positive"> <div class="buttons"> <button class="button button-icon icon ion-ios-minus-outline" ng-click="data.showDelete = !data.showDelete; data.showReorder = false"></button> </div> <h1 class="title">Ionic Delete/Option Buttons</h1> <div class="buttons"> <button class="button" ng-click="data.showDelete = false; data.showReorder = !data.showReorder"> Reorder </button> </div> </ion-header-bar> <ion-content>  <ion-list show-delete="data.showDelete" show-reorder="data.showReorder"> <ion-item ng-repeat="item in items" item="item" href="#/item/{{item.id}}" class="item-remove-animate"> Item {{ item.id }} <ion-delete-button class="ion-minus-circled" ng-click="onItemDelete(item)"> </ion-delete-button> <ion-option-button class="button-assertive" ng-click="edit(item)"> Edit </ion-option-button> <ion-option-button class="button-calm" ng-click="share(item)"> Share </ion-option-button> <ion-reorder-button class="ion-navicon" on-reorder="moveItem(item, $fromIndex, $toIndex)"></ion-reorder-button> </ion-item> </ion-list> </ion-content> </body> </html> ``` ### CSS 代码 ``` body { cursor: url('http://www.runoob.com/try/demo_source/finger.png'), auto; } ``` ### JavaScript 代码 ``` angular.module('ionicApp', ['ionic']) .controller('MyCtrl', function($scope) { $scope.data = { showDelete: false }; $scope.edit = function(item) { alert('Edit Item: ' + item.id); }; $scope.share = function(item) { alert('Share Item: ' + item.id); }; $scope.moveItem = function(item, fromIndex, toIndex) { $scope.items.splice(fromIndex, 1); $scope.items.splice(toIndex, 0, item); }; $scope.onItemDelete = function(item) { $scope.items.splice($scope.items.indexOf(item), 1); }; $scope.items = [ { id: 0 }, { id: 1 }, { id: 2 }, { id: 3 }, { id: 4 }, { id: 5 }, { id: 6 }, { id: 7 }, { id: 8 }, { id: 9 }, { id: 10 }, { id: 11 }, { id: 12 }, { id: 13 }, { id: 14 }, { id: 15 }, { id: 16 }, { id: 17 }, { id: 18 }, { id: 19 }, { id: 20 }, { id: 21 }, { id: 22 }, { id: 23 }, { id: 24 }, { id: 25 }, { id: 26 }, { id: 27 }, { id: 28 }, { id: 29 }, { id: 30 }, { id: 31 }, { id: 32 }, { id: 33 }, { id: 34 }, { id: 35 }, { id: 36 }, { id: 37 }, { id: 38 }, { id: 39 }, { id: 40 }, { id: 41 }, { id: 42 }, { id: 43 }, { id: 44 }, { id: 45 }, { id: 46 }, { id: 47 }, { id: 48 }, { id: 49 }, { id: 50 } ]; }); ```
