所以,我有一个选择列表,我试图动态选择项目.问题是,即使doe表达式被评估为“true”,该选项仍未被选中

<label for="articlePage">Page:</label>
<select class="form-control pageList" name="articlePage" required="" ng-model="article.page_ID">
    <option ng-repeat="page in pages" ng-selected ="{{page.id == article.page_ID}}" value={{page.id}}>{{page.name}}</option>
</select><br>

范围(页数)：

$scope.pages = [
        { name: "Home",id: "1" },{ name: "Plugs",id: "2" },{ name: "Pack Bedding",id: "3" },{ name: "Pot Bedding",id: "4" },{ name: "Poinsettias",id: "5" },{ name: "Sales",id: "6" },{ name: "Process Quality",id: "7" },{ name: "Environment",id: "8" },{ name: "Process Technology",id: "9" },{ name: "Process Control",id: "10" },{ name: "Infrastructure",id: "11" },{ name: "News",id: "12" },{ name: "About",id: "13" },{ name: "Contact",id: "14" },{ name: "Find Us",id: "15" },{ name: "Key Personnel",id: "16" },{ name: "Recruitment",id: "17" },{ name: "Legal Information",id: "18" },{ name: "Hidden",id: "19" }
];

还有一项服务正在检索我的文章,我知道我说得对,就像我说的那样,表达式正在评估中.这是一个打印屏幕,以证明：

有没有人知道为什么没有选择该选项？

谢谢！
