1. Regarding the drag-and-drop plug-in, it is recommended to use it angular-sortable-view，原因：（1）使用简单方便（2）除了Angular No additional dependencies are required.
2. I have written a small example here. You can click to see it. If it is the result you want, you can read the content below. If you are not satisfied, there is no need to read the content below.

Code part:
1.index.html


    
        

            

                

                    
name: {{item.name}}
                    value: {{item.age}}
                
                拖拽手柄
            
        
        
        
            {{vm.items}}

2.app.js

(function(){
    angular.module('MyApp', ['angular-sortable-view'])
        .controller('MyController', MyController)
        .service('DataService', DataService);

    MyController.$inject = ['DataService', '$q', '$scope'];
    DataService.$inject = ['$http'];

    function MyController(DataService, $q, $scope){
        var vm = this;

        activate();
        function activate() {
            var promises = [get_data()];
            return $q.all(promises).then(function() {
                // promise被resolve时的处理
            });
        }

        function get_data(){
            // 我这里只是示范,真正的promise不是这样写的
            vm.items = DataService.get_data();
            console.log(vm.items);
        }

    }

    function DataService($http){
        // 为了简单起见,我没有真正的发送一个http请求,而是使用了假数据.

        /*var url = 'http://example.com';
        var params = {
            key: 'your_key'
        };

        var service = {
            get_data: get_data
        };

        return service;

        function get_data(){
            // 你使用$http获取数据
            return $http.get(url, params)
                .then(function(res){
                    // 你的处理
                });
        }*/


        // 上面是实际中会用到的,我下面使用了假数据

        var data = [
            {name: 'dreamapple1', age: 1},
            {name: 'dreamapple2', age: 2},
            {name: 'dreamapple3', age: 3},
            {name: 'dreamapple4', age: 4},
            {name: 'dreamapple5', age: 5},
            {name: 'dreamapple6', age: 6}
        ];

        var service = {
            get_data : get_data
        };

        return service;

        function get_data(){
            return data;
        }

    }

})();

}

Okay, that’s basically it, I hope it can help you ^_^.
