如何从 ui-select 多个中获取 selected 选项

Question

我在弄清楚如何从 ui-select 获取多 select 形式的 selected 值时遇到了一些问题。我做了一个片段来告诉你我想做什么。在我的 html 中，我制作了一个带有 ng-change-event 回调的 ui-select：ng-change="onDatasetChanged(whatShouldBehere?)"。 When the option is selected, I want to print the selected model only inside the onDatasetChanged()-method in my controller.

angular.module('myApp',['ui.select']).controller('MyController', function ($scope) {
  
  $scope.myUiSelect={model:{}}; // encapsulate your model inside an object.
  $scope.availableData=["a","b","c"]; //some random options
  
  $scope.onDatasetChanged = function(selectedValue){
    console.log("selectedValue",selectedValue);
  }
  
});

<body ng-app="myApp" ng-controller="MyController">
  
  
  
  <ui-select multiple ng-model="myUiSelect.model" close-on-select="false" title="Choose a dataset" ng-change="onDatasetChanged(whatShouldBehere?)">
    <ui-select-match placeholder="Select something">{{$item.label}}</ui-select-match>
      <ui-select-choices repeat="data in availableData | filter:$select.search">
                        {{data}}
      </ui-select-choices>
  </ui-select>
  
  
  
</body>

在对 ui-select-directive 的存储库页面进行一些研究之后我认为您可以像这样使用 on-select 事件绑定： on-select="onSelect($item, $model)"。查看更新后的代码段：

angular.module('myApp',['ui.select']).controller('MyController', function ($scope) {
  
  $scope.myUiSelect={model:{}}; // encapsulate your model inside an object.
  $scope.availableData=["a","b","c"]; //some random options
  
  $scope.onSelect = function(item,model){
    console.log("selectedItem",item);
  }
  
});

    <ui-select-match placeholder="Select something">{{$item.label}}</ui-select-match>
      <ui-select-choices repeat="data in availableData | filter:$select.search">
                        {{data}}
      </ui-select-choices>
  </ui-select>
  
  
  
</body>
