在AngularJS中执行ng-repeat内的函数 [英] Execute a function inside ng-repeat in AngularJS

问题描述

我想在ng-repeat中执行一个函数来检索要显示的其他数据。

I would like to execute a function inside a ng-repeat to retrieve some other data to show.

例如我有一个公寓列表。我使用 ng：repeat 显示此列表，而不是我希望向所有者显示的每个公寓，而不是 u.Apartments 。所以我的 getInq 函数调用服务来获取指定公寓的所有者。这对我来说似乎是逻辑，但它不起作用。
它返回 10 $ digest（）迭代次数。正在中止！ 错误。

For example I've a list of Apartments. I show this list using ng:repeat, than for each Apartment I would like to show the Owner, that is not the u.Apartments. So my getInq function make a call to a service to get the owner of a specified apartment. It seems to be logic for me, but it doesn't work. It returns the "10 $digest() iterations reached. Aborting!" error.

我有这段代码：

<div ng:repeat="u in units">
            <div ng:repeat="a in u.Apartments">
                <div class="targhetta" style="margin-top:10px">{{a.Name}}</div>
                <br />{{getInq(a.ApartmentId)}}
                <table>
                    <tr ng:repeat="cs in a.CS">
                        <td>{{cs.Position}}</td>
                        <td>{{cs.Code}}</td>
                    </tr>
                </table>
            </div>
        </div>

在控制器中：

$scope.getInq = function (idApp) {
            $http.get('http://localhost:8081/api/registry/GetLastInq?processdata=' + (new Date()).getTime() + '&appartamentoId=' + idApp, { headers: headers })
            .success(function (data2) {
                $scope.nomeInquilinoVw = data2.Name;
                $scope.cognomeInquilinoVw = data2.Surname;
                $scope.nomeCognome = $scope.nomeInquilinoVw + " " + $scope.cognomeInquilinoVw;
            })
            .error(function () {
                $scope.success = false;
                $scope.error = "There was an error!";
            });
            return $scope.nomeCognome;
        }

有任何建议吗？

推荐答案

您应该在ng-repeat的任何数据中创建自定义指令传递，并执行您想要的任何操作。该指令将在每个ng-repeat循环上触发其链接函数

You should create a custom directive pass in any data you want from the ng-repeat and do any action you want. The directive will fire its link function on every ng-repeat loop

var app = angular.module('myApp', [])
.controller('myCtrl', function($scope){
  
  $scope.data = ['a', 'b', 'c'];
  
})
.directive('myDirective', function(){
  return {
    restrict: "A",
    template: '<div>{{ myDirective }}</div>', // where myDirective binds to scope.myDirective
    scope: {
      myDirective: '='
    },
    link: function(scope, element, attrs) {
      console.log('Do action with data', scope.myDirective);
    }
  };
});

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

<div ng-app="myApp">

  <div ng-controller="myCtrl">
  
    <ul>
      <li ng-repeat="item in data" my-directive="item">{{ item }}</li>
    </ul>
    
  </div>
  
</div>

检查控制台是否有动作
