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. Berkenaan pemalam drag-and-drop, adalah disyorkan untuk menggunakan angular-sortable-view atas sebab: (1) Ia mudah dan mudah digunakan (2) Tiada kebergantungan tambahan diperlukan kecuali Angular .
    2. Saya ada tulis contoh kecil di sini Anda boleh klik untuk melihatnya .

    Bahagian kod:
    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;
}

    Baiklah, itu pada asasnya, saya harap ia dapat membantu anda ^_^.

    1. Portal contoh laman web rasmi
    2. Jika ada yang tidak jelas tentang kod, anda boleh lihat contoh saya.
