Question

Ng-Selected不能选择正确的选项，即使比较正确。我可以在输出中看到比较工作正常。

我的实际问题是，即使比较成功之后（不同于其他问题，Int和字符串比较返回false）。为什么不选择该选项。

我不能将option用于其他目的。其次，在复制到代码段时有一些错误。这就是为什么它不起作用。

var app = angular.module("app", []);
app.controller("HelloController", function($scope) {

  $scope.data = {
    ExpertiseId: null,
    userExperties = [{
      id: 1,
      ExpertyTitle: "Human Resource"
    }, {
      id: 2,
      ExpertyTitle: "Account & Finance"
    }, {
      id: 3,
      ExpertyTitle: "Information Technology"
    }, {
      id: 4,
      ExpertyTitle: "Business Management"
    }];
  }
});

    <option style="display:none" value="">CHOOSE_EXPERTISE</option> 
    <option ng-selected="{{option.id.toString() == data.ExpertiseId.toString()}}" value="{{option.id.toString()}}" ng-repeat="option in data.userExperties">{{option.id.toString()==data.ExpertiseId.toString()}}---{{option.ExpertyTitle}}</option>

您的代码中有几个错误。

对象表示法错误
您在任何地方都不能使用ng-controller
将脚本文件放置在html标签之外。
ng选择的语法也是错误的

我已更正它们并更新了代码段。

var app = angular.module("app", []);
app.controller("HelloController", function($scope) {

  $scope.data = {
    ExpertiseId: 2,
    userExperties : [{
      id: 1,
      ExpertyTitle: "Human Resource"
    }, {
      id: 2,
      ExpertyTitle: "Account & Finance"
    }, {
      id: 3,
      ExpertyTitle: "Information Technology"
    }, {
      id: 4,
      ExpertyTitle: "Business Management"
    }]
  }
});
