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。
