angular drag and drop (ngDraggable) 笔记
这是原文 https://github.com/fatlinesofcode/ngDraggable
这是另一个dnd,这比较灵活,可以监听事件。我只用简单的排序功能,其他没去了解太多。有机会遇到功能扩展,会在这里更新。
功能与需求:
-在angular filter orderBy 里 reorder 对象。
基本注入一下和写些controller
var app = angular.module('App', ['ngAnimate','ngDraggable']); app.controller("App.ctrl", ['$scope', '$timeout', function ($scope, $timeout) { $scope.FAQs = [ { id:1, question: 'q1', answer: 'a1', sort : 1 }, { id: 2, question: 'q2', answer: 'a2', sort: 2 }, { id: 3, question: 'q3', answer: 'a3', sort: 3 } ]; $scope.onDropComplete = function (dragResource, dropResource) { var sortRecord = dragResource.sort; dragResource.sort = dropResource.sort; dropResource.sort = sortRecord; } }]) </script>
HTML
<div ng-repeat="FAQ in FAQs | orderBy : 'sort' : true" ng-drop="true" ng-drop-success="onDropComplete($data,FAQ)" class="card-panel "> <div ng-drag="true" ng-drag-data="FAQ" class="row"> <div class="col s10"> <p>{{FAQ.question}}</p> <p>{{FAQ.answer}}</p> </div> <div class="col s2 center"> <a class="btn-floating waves-effect waves-light"><i class="mdi-action-delete"></i></a> <a href="#createFAQ" class="btn-floating waves-effect waves-light modal-trigger"><i class="mdi-editor-mode-edit"></i></a> </div> </div> </div>
CSS
[ng-drag] { -moz-box-sizing: border-box; -webkit-box-sizing: border-box; box-sizing: border-box; -moz-user-select: -moz-none; -khtml-user-select: none; -webkit-user-select: none; -ms-user-select: none; user-select: none; } [ng-drag] { cursor: move; } [ng-drag].drag-over { //开始drag位置,去到其他elem是没有反应的,这里是设计错误 } [ng-drag].dragging {
//开始drag位置 background-color: #e8f5e9 ; } [ng-drop] { } [ng-drop].drag-enter {
//drag进入 background-color: #f1f8e9; } [ng-drop] div {
//这是为了在drag时,可以在所有elem的之上 position: relative; z-index: 2; }
原理:
在drag complete时,出发事件,把2个对象的sort对换。
