Question

我想从多选控件加载数组对象，然后我想要加载模型对象名为＆＃34; name＆＃34;使用他的名字和年龄值，然后我想从选择和加载模型对象加载数组....但选择控件的ng模型不起作用：/

<input type="text" class="form-control" ng-model="model.name" placeholder="Put your name..." />
<input type="text" class="form-control" ng-model="model.age" placeholder="Put your age..." />

<!--Select pets for model person-->
<select ng-repeat="pets in arrayFromApi" class="selectpicker" multiple>
   <option id="{{pet.id}}" ng-model="model.pets.id">{{pet.name}}</option>
</select>


<script>
   var app = angular.module("myApp", []);
   app.controller("myCtrl", function($scope) {

    $scope.model = { "name":"", "age":"", "pets" :[ {"id":""} ] };

    $scope.arrayFromApi = function() {
          ......
        this function get id names
     }
 });
 </script>

Answer 1

您可能需要使用ng-options。您可以尝试使用ng-repeat，但它应该只在选项标签上。

Answer 2

避免在下拉列表中使用ng-repeat，这会导致一些性能问题。而是使用ng-options。

对于havint这个名字，年龄和宠物的模型。检查mixData函数。

    <input type="text" class="form-control" ng-model="model.name" placeholder="Put your name..." />
    <input type="text" class="form-control" ng-model="model.age" placeholder="Put your age..." />

    <!--Avoid ng-repeat in dropdowns-->
    <!--Select pets for model person-->
    <select ng-change="mixData()" class="selectpicker" multiple ng-model="myPets" ng-options="pet.id as pet.name for pet in arrayFromApi">
       <option value="">Select...</option>
    </select>

    <!--<select ng-repeat="pets in arrayFromApi" class="selectpicker" multiple>
       <option id="{{pet.id}}" ng-model="model.pets.id">{{pet.name}}</option>
    </select>-->


    <script>
       var app = angular.module("myApp", []);
       app.controller("myCtrl", function($scope) {

        $scope.model = { "name":"", "age":"", "pets" :[ {"id":""} ] };

        $scope.arrayFromApi = function() {
              ......
            this function get id names
         }

        $scope.mixData = function(){
           $scope.model.pets = $scope.myPets;
        };
     });
     </script>

如果您使用select作为角度标准ng-options，使用此属性，您可以处理视图中的所有内容，并将多个类型返回数组作为{id: n}添加到控制器中，效果会更好

＆＃13;

var app = angular.module("myApp", []);
app.controller("myCtrl", function($scope) {

  $scope.model = {};

  //from api
  $scope.arrayFromApi = [{
      id: 1,
      name: 'test'
    },
    {
      id: 2,
      name: 'test2'
    }
  ];

  $scope.getDetails = function() {
    console.log($scope.model);
  }
});

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="myCtrl">
  <input type="text" ng-model="model.name" placeholder="Put your name..." />
  <input type="text" ng-model="model.age" placeholder="Put your age..." />

  <!--Select pets for model person-->
  <select ng-model="model.pets" ng-options="{id: item.id} as item.name for item in arrayFromApi" multiple></select>

  <button ng-click="getDetails()">save</button>
</div>
