Question

是否可以选择从head -n5 file1 | parallel -a - -j 4 echo #this works head -n5 file1 | parallel -a - -j 4 ./myscript #this doesn't过滤数组$scope.items中存在 ID 的地方？

$scope.myitems

演示：http://codepen.io/anon/pen/rOeGYB

ng-repeat="item in items | filter:{item.id == myitems}

angular.module('myapp', [])
  .controller("mycontroller", function($scope) {
    $scope.items = [
      {
        "id": 1,
        "name": "Melodie"

您的问题是您正在尝试匹配您正在迭代的对象的子属性。

来自文档：

请注意，命名属性将匹配同一级别的属性只有，而特殊的$属性将匹配相同的属性等级或更深。例如。一个数组项，如{name：{first：＆＃39; John＆＃39;，last：＆＃39; Doe＆＃39;}}将不会被{name：＆＃39; John＆＃39;}匹配，但将被匹配 {$：＆＃39; John＆＃39;}。

我建议您自定义过滤器。我已经通过实现自定义过滤器，您的需求的工作副本来更改您的代码。

<li class="list-group-item" ng-repeat='item in items | customArray:myitems:"id"'>{{item.name}}</li>

使用此答案的优秀过滤器：

.filter('inArray', function($filter){
    return function(list, arrayFilter, element){
        if(arrayFilter){
            return $filter("filter")(list, function(listItem){
                return arrayFilter.indexOf(listItem[element]) != -1;
            });
        }
    };
});

Answer 3

angular.forEach($scope.items, function (v, k) { 
   console.log($scope.myitems[v.id - 1]);
   $scope.myitems[v.id- 1].name = v.name;
}, $scope.myitems);

只是为了一些提示。希望帮助

上面的例子由Kashif Mustafa给出完美的作品。我们唯一需要做的改变是将字符串解析成整数。

CSHTML：

     var eIds = detail.entityIds;
     var eArray = eIds.split(",");

     if (eArray.length > 0) {
         $scope.showEntities = true;
         $scope.showNone = false;
         for (var i = 0; i < eArray.length; i++) {
            $scope.SelectedEntities.push(parseInt(eArray[i]));
           }
     }

控制器：

(your controller).filter('customArray', function ($filter) {
    return function (list, arrayFilter, element) {
        if (arrayFilter) {
            return $filter("filter")(list, function (listItem) {
                return arrayFilter.indexOf(listItem[element]) != -1;
            });
        }
    };
});
