angular.js - angular sortable 可以拖动但停止时位置无法发生变化

html代码如下:

<p ui-sortable="sortableOptionsList[$index]" class="apps-container"  ng-model="rawScreens[$index]" ng-repeat="app in rawScreens track by $index">
    {{app.name}}
    <p ng-repeat="item in app.items track by $index">
        {{$index}}{{item.title}}
    </p>
</p>

js代码如下:

$scope.rawScreens = itemStorage.itemList('http://localhost:8080/demo/demo.json').success(function(data, status, headers, config) {
    $scope.rawScreens = data;
    var sol = [];
    for (i = 0; i < $scope.rawScreens.length+1; i++) {
        sol[i] = createOptions(i);
    }
    $scope.sortableOptionsList = sol;
});


function createOptions(listName) {
    var _listName = listName;
    var options = {
        placeholder: "app",
        connectWith: ".apps-container"
    };
    return options;
}

json数据如下:

[
    {
        "id":"状态1",
        "name":"状态1",
        "items":[{
            "title":"测试数据1"
        },{
            "title":"测试数据2"
        }]
    },{
        "id":"状态A",
        "name":"状态A",
        "items":[{
            "title":"测试数据a"
        },{
            "title":"测试数据b"
        }]
    }
]

拖动后在deactivate之后,stop之前报错

    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

    <body ng-app="MyApp">
        <p ng-controller="MyController as vm" class="background">
            <p sv-root sv-part="vm.items" class="sv-container">
                <p ng-repeat="item in vm.items" sv-element class="sv-cell">
                    <p>
                        <p>name: {{item.name}}</p>
                        <p>value: {{item.age}}</p>
                    </p>
                    <span class="sv-handle" sv-handle>拖拽手柄</span>
                </p>
            </p>
            <hr/>
            <p class="show-data">
                {{vm.items}}
            </p>
        </p>
    
    </body>

    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;
            }
    
        }
    
    })();

    3.style.css

    *{
        padding: 0;
        margin: 0;
    }
    html{
        width: 100%;
        height: 100%;
    }
    body{
        width: 100%;
        height: 100%;
    }
    .background{
        width: 100%;
        height: 100%;
        background-color: #f0f0f0;
    }
    .sv-container{
        margin: 0 auto;
        width: 30%;
        height: 600px;
        background-color: #b3d4fc;
        position: relative;
    }
    
    .sv-cell{
        width: 80%;
        margin: 10px auto;
        height: 90px;
        background-color: #0000FF;
        position: relative;
    }
    .sv-handle{
        cursor: pointer;
        position: absolute;
        left: -30px;
        width: 80px;
        height: 20px;
        line-height: 20px;
        border: 1px solid black;
        z-index: 0;
    }
    .show-data{
        width: 30%;
        margin: 0 auto;
        text-align: center;
        color: #000;
    }

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