AngularJS.When select have ng-model attribute, ng-selected not working

问题描述：

我正在尝试在我的 option 元素中设置 ng-selected，selected 属性设置为 true，但 option 没有被选中，当我从 select 中删除 ng-model 时，一切都变得有效.

I'm trying to set ng-selected in my option element, selected attribute is set to true, but option not selected, When I remove ng-model from select all become working.

问题:当我使用模型时如何选择option?

The question: How to make option selected, when I'm using the model?

这是我的plunker(selected 在这里不起作用)

Here is my plunker (selected not working here)

我的代码:

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

app.controller("TestController", ["$scope", function($scope) {
  $scope.test = 1;
  $scope.array = [
        {"id": 1, "name": "first"}, 
        {"id": 2, "name": "second"}, 
        {"id": 3, "name": "third"}
      ];
}]);

我的模板:

  <body ng-controller="TestController">
    Selected item must be {{ array[test-1].name }}
    <select ng-model="myModel">
      <option value="">Choose item..</option>
      <option ng-repeat="item in array" 
              ng-value="item.id" 
              ng-selected="item.id == test">
        {{ item.name }} ({{item.id == test}})
      </option>
    </select>
  </body>

非常感谢您的帮助！

不要将 ngSelected 与 ngRepeat 一起使用.使用 ngOptions:

Don't use ngSelected with ngRepeat. Go with ngOptions:

  <body ng-controller="TestController">
    Selected item must be {{ array[test-1].name }}
    <select ng-model="myModel" ng-options="item.id as item.name for item in array">
      <option value="">Choose item..</option>
    </select>
  </body>
