  • 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。
