Question

我知道堆栈中类似于我的问题。但不同的是，我在控制器中为我的下拉列表选择了硬编码，然后我希望下拉列表默认显示模型中的值。

HTML：

<div class="form-group">
                            <label class="col-md-3 control-label" for="talent.rating">Rating*</label>
                            <div class="col-md-9">
                                <select ng-model="talent.rating"  validator="required" required-error-message="Rating is required" name="talent.rating" ng-options="obj.value as obj.text for obj in array"></select>
                            </div>
                        </div>

控制器：

myApp.controller('editTalentController', ['$scope', '$rootScope', 'talentResolved', 'accountResolved', 'talentServices', '$location', 'ngDialog', '$window',
    function ($scope, $rootScope, talentResolved, accountResolved, talentServices, $location, ngDialog, $window) {

        $scope.talent = talentResolved.data;
            $scope.array = [{ value: '1', text: '1' }, { value: '2', text: '2' }, { value: '3', text: '3' }, { value: '4', text: '4' }, { value: '5', text: '5' }];

   }]);

型号：

$scope.talent: Object
createdOn:    "2017-02-03T00:58:20.0999066"
employee    :    Object
fromAccount    :    Object
id    :130
inDate    :    "2017-02-01T05:30:00"
movedOutOfBench    :    false
outTill    :    "2017-05-02T05:30:00"
rating    :    2
remark    :    "asd"
resumePath    :    ""

我做错了什么？请提供修复代码。

找到了解决方案。

HTML：

 <select ng-model="talent.rating" convert-to-number>
                                    <option value="1">1</option>
                                    <option value="2">2</option>
                                    <option value="3">3</option>
                                    <option value="4">4</option>
                                    <option value="5">5</option>
                                </select>

控制器：

myApp.directive('convertToNumber', function () {
    return {
        require: 'ngModel',
        link: function (scope, element, attrs, ngModel) {
            ngModel.$parsers.push(function (val) {
                return val != null ? parseInt(val, 10) : null;
            });
            ngModel.$formatters.push(function (val) {
                return val != null ? '' + val : null;
            });
        }
    };
});

即使我尝试将值作为数字给出，如：

$scope.array = [{ value: 1, text: '1' }, { value: 2, text: '2' }, { value: 3, text: '3' }, { value: 4, text: '4' }, { value: 5, text: '5' }];, angular was considering it as string. Don't know why.
When inspecting from console,it was like - https://hastebin.com/ugatisazey.vbs

该指令帮助我解决了这个问题。

使用angularJS从下拉列表中选择模型中的值
