来自对象数组的angular JS access属性

Question

$completed = [Object { count(1)="7", gid="306"}, Object { count(1)="1", gid="311"}]

如何在HTML模板中获取count(1) = 7？

<div class="{{ completed | filter : group.gid }}">

所以

{{ completed | filter : group.gid }}  

评估为

[{ "count(1)":"7","gid":"306"}]

我只需要'7'？

你走了：

<div class="{{(completed | filter: group.gid)[0]["count(1)"]}}" >

参见工作演示：

var app = angular.module("sa", []);

app.controller("FooController", function($scope) {

  $scope.group = {
    gid: 7
  };

  $scope.completed = [{
    "count(1)": "7",
    gid: "306"
  }, {
    "count(1)": "1",
    gid: "311"
  }]
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

<div ng-app="sa" ng-controller="FooController">
    {{(completed | filter: group.gid)[0]["count(1)"]}}
</div>
