Question

我正在AngularJS中实现一个搜索功能，我希望有一条消息＆＃34;没有找到结果＆＃34;什么时候没有比赛。由于我只过滤了一些字段而不是所有字段，我编写了一个单独的过滤函数，应用于ng-if以检查条目是否与搜索匹配。现在我需要在ng-repeat完成后计算生成的面板，所以我尝试使用指令after-repeat，并从results内部SearchController为<div ng-if="searchctrl.results<1">No matches.</div> <uib-accordion close-others="true"> <uib-accordion-group ng-if="searchfilter(lokal)" is-open="isopen" ng-repeat="lokal in lokale | orderBy:'name'" after-repeat> [...] </uib-accordion-group> </uib-accordion>变量赋值指令，但它没有做任何事情。

HTML：

var app = angular.module('ZoiglApp', ['ngAnimate', 'ui.bootstrap', 'ngRoute', 'ngTouch', 'leaflet-directive']);

app.config(function($routeProvider) {
    $routeProvider
    [...]
    .when('/search/:searchterm', {
        controller: 'SearchController',
        controllerAs:'searchctrl',
        templateUrl: 'views/search.html'
    })
    .otherwise({
        redirectTo: '/home'
    });
});

app.js（带有我的SearchController的控制器）：

app.directive('afterRepeat', function() {
    return {
        restrict: 'A',
        link: function(scope, elem, attrs) {
            if(scope.$last) {
                scope.searchctrl.results = angular.element('.panel').length;
            }
        }
    };
});

afterRepeat.js：

var modalcontent = data.getValue(row, 0);
$("#inputId").html(modalcontent);

编辑：我还在寻找解决方案。我已经回答了以下两条建议，并解决了我们遇到的问题。如果有人试图找到我的错误，那将是非常好的

Answer 1

只需在控制器中的另一个列表中过滤您的列表，然后在视图中使用这个新列表。

$scope.filteredLokale = $filter('filter')($scope.lokale, { param: "paramValue" });

之后，使用“length”参数计数。

    <uib-accordion close-others="true"> 
    <uib-accordion-group is-open="isopen" ng-repeat="lokal in filteredLokale | orderBy:'name'" >
        [...]
    </uib-accordion-group>
</uib-accordion>
{{ filteredLokale .length }}

您应该为{% if app.user and is_granted('ROLE_ADMIN') %} You are logged in and you're an administrator. You can remove is_granted() if you don't need to check for a specific role. This is just a full example. {% else %} Please register. {% endif %}功能创建角度过滤器，而不是使用public class ImageAdapter extends BaseAdapter { private Context mContext; Integer [] imageIDs; public ImageAdapter(Context c, int ...pos){ mContext = c; imageIDs = new Integer[pos.length];//it's for set the number items for (int i=0; i<pos.length; i++){ if (i<mThumbIds.length-1){ imageIDs[i]=mThumbIds[pos[i]]; } } //_____________________________ } private Integer[] mThumbIds = { R.drawable.alemania_2006, R.drawable.arg_1978, R.drawable.brasil_2014, R.drawable.francia_1998, R.drawable.rusia_2018, R.drawable.sudafrica_2010 }; @Override public int getCount() { return imageIDs.length; } @Override public Object getItem(int position) { return imageIDs[position]; } @Override public long getItemId(int position) { return 0; } @Override public View getView(int position, View convertView, ViewGroup parent) { ImageView imageView; if (convertView == null){ imageView = new ImageView(mContext); imageView.setLayoutParams(new GridView.LayoutParams(350, 350)); imageView.setScaleType(ImageView.ScaleType.CENTER_CROP); imageView.setPadding(4, 4, 4, 4); }else{ imageView = (ImageView) convertView; } imageView.setImageResource(mThumbIds[position]); return imageView; } } public class Playing extends AppCompatActivity{ int []img={0,1,2,3,4,5}; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_playing); GridView gridview = (GridView) findViewById(R.id.gridView); gridview.setAdapter(new ImageAdapter(this, img)); gridview.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Toast.makeText(Playing.this, "" + position, Toast.LENGTH_SHORT).show(); //cambiar de vista la imagen al clickear: } }); } }。然后，您可以将过滤后的数组分配给名为searchFilter的变量，如此

ng-if

使用ng-if过滤ng-repeat后得到结果数
