browserLink：37未捕获错误：语法错误，无法识别的表达式：输入＃{role}（...）

// template

<div ng-repeat="role in roles">
    <input type="checkbox" id="{{role}}" value="{{role}}" ng-model="role" ng -checked="getCheckedTrue[{{role}}]" />
    {{role}}
</div>

// JS

$scope.roles = [
   'Dentist',
   'HeartSurgeon',
   'Cance'
];

$scope.getCheckedTrue = function (data) {
    console.log(data);
    $http({
        method: 'GET',
        url: '/Doctor/getType?searchString=' + $scope.role,
    }).then(function successCallback(responce) {
        $scope.Doctors = responce.data;
    }, function errorCallback(response) {
        alert("Error : " + response.data.ExceptionMessage);
    });
};`

//控制器

    public JsonResult getType(string searchString)

    {

        var Doctor = db.DocMaster.Where(f =>
      f.DocType.StartsWith(searchString)).ToList();
        var JsonResult = Json(Doctor, JsonRequestBehavior.AllowGet);

        JsonResult.MaxJsonLength = int.MaxValue;

        return JsonResult;

    }

Answer 1

 //For getting the all records from database. Controller
 //c# controller
    public JsonResult get(string searchString)
     {
        var Doctor = db.DocMaster.Where(f =>
      f.DocType.StartsWith(searchString)).ToList();
        var JsonResult = Json(Doctor, JsonRequestBehavior.AllowGet);
        JsonResult.MaxJsonLength = int.MaxValue;
        return JsonResult;
    }

//视图

                <div ng-repeat="(typeKey, typeVal) in roles">
                    <div ng-repeat="value in typeVal">
                        <label>
                            <input type="checkbox"
                                   ng-model="x"
                                   ng-change="setOutput(typeKey, $index, value)">{{value}}
                        </label>
                    </div>
               </div>

//角控制器

 $scope.outputs = {};
$scope.setOutput = function (typeKey, $index, value) {
    $scope.Doctors = {};
    $http({
        method: 'POST',
        url: '/Doctor/get?searchString='+value,
    }).then(function successCallback(response) {
        // this callback will be called asynchronously
        // when the response is available
        console.log(response);
        $scope.Doctors = response.data;
    }, function errorCallback(response) {
        // called asynchronously if an error occurs
        // or server returns response with an error status.
        alert("Error : " + response.data.ExceptionMessage);
    });
};

Answer 2

按名称而不是输入引用输入

Answer 3

我认为ng-checked =“getCheckedTrue [{{role}}]”实际上应该是ng-checked =“getCheckedTrue [role]”

Answer 4

getCheckedTrue是函数，您将它用作数组。

所以，而不是getCheckedTrue [{{role}}]，它应该是getCheckedTrue（{{role}}）

此外，角色值为字符串，因此您最好使用getCheckedTrue（'{{role}}'）
