Question

我有一个简单的过滤器，它根据SQL的输入是否为真来放置两个语句之一

    app.filter('yesNo', function() {
      return function(input) {
          return (input == '1') ? 'Skal tjekkes!' : 'Alt OK';
      }
  });

然后应该根据它改变一个菜单项;

    <li role="presentation"><a href="#" data-ng-click="statusFilter = 'Ny ordre'">New Orders
      <div ng-if="input == '1' | outdated">
          <p>Needs to be checked: {{(orders | filter:{status:'ny ordre', outdated: '1'}).length}}</p>
            </div>
            <div ng-if="!input == '1' | outdated">Shows regardless</div>

      </a></li>

我错过了什么，不知道是什么。：（

这里有一个示例，说明如何使用自定义过滤器功能：http://jsfiddle.net/alexdumitrescu/zv6cf7nq/

＆＃13;

var myApp = angular.module('myApp', [])
  .filter('myfilter', function() {
    return function(orders) {
      return orders.filter(function(order) {
        return order.outdated == '1';
      })
    }
  });

function MyCtrl($scope) {
  $scope.orders = [{
    status: 'my order1',
    outdated: '1'
  }, {
    status: 'my order2',
    outdated: '0'
  }];
}

＆＃13;

<div ng-controller="MyCtrl">
  {{orders | myfilter}}
</div>

＆＃13;
