AngularJs向服务传递参数

我想通过post方法输入Id，并从数据库中获取该Id的数据。我当前在控制器代码中收到一个错误“employeeID未定义”

控制器代码：

$scope.employeeID = '10';


function test() {
    var getData = myService.getEmployee(employeeID);
    getData.then(function (emp) {
        $scope.employees2 = emp.data;

    }, function () {
        alert('Error in getting records');
    });
}

test(employeeID);

this.getEmployee = function (employeeID) {
    var response = $http({
        method: "post",
        url: "Home/getEmployeeByNo",
        params: {
            id: JSON.stringify(employeeID)
        }
    });
    return response;
}

    public JsonResult getEmployeeByNo(string EmpNo)
    {
        using (InsiteEntities dataContext = new InsiteEntities())
        {
            int no = Convert.ToInt32(EmpNo);
            var employeeList = dataContext.Employee.Find(no);
            return Json(employeeList, JsonRequestBehavior.AllowGet);
        }
    }

服务代码：

$scope.employeeID = '10';


function test() {
    var getData = myService.getEmployee(employeeID);
    getData.then(function (emp) {
        $scope.employees2 = emp.data;

    }, function () {
        alert('Error in getting records');
    });
}

test(employeeID);

this.getEmployee = function (employeeID) {
    var response = $http({
        method: "post",
        url: "Home/getEmployeeByNo",
        params: {
            id: JSON.stringify(employeeID)
        }
    });
    return response;
}

    public JsonResult getEmployeeByNo(string EmpNo)
    {
        using (InsiteEntities dataContext = new InsiteEntities())
        {
            int no = Convert.ToInt32(EmpNo);
            var employeeList = dataContext.Employee.Find(no);
            return Json(employeeList, JsonRequestBehavior.AllowGet);
        }
    }

家庭控制器代码：

$scope.employeeID = '10';


function test() {
    var getData = myService.getEmployee(employeeID);
    getData.then(function (emp) {
        $scope.employees2 = emp.data;

    }, function () {
        alert('Error in getting records');
    });
}

test(employeeID);

this.getEmployee = function (employeeID) {
    var response = $http({
        method: "post",
        url: "Home/getEmployeeByNo",
        params: {
            id: JSON.stringify(employeeID)
        }
    });
    return response;
}

    public JsonResult getEmployeeByNo(string EmpNo)
    {
        using (InsiteEntities dataContext = new InsiteEntities())
        {
            int no = Convert.ToInt32(EmpNo);
            var employeeList = dataContext.Employee.Find(no);
            return Json(employeeList, JsonRequestBehavior.AllowGet);
        }
    }

改变

从

到

---

您应该在

params

对象中传递

EmpNo

参数，而不是

id

参数，这样URL的形式就像

Home/getEmployeeByNo？EmpNo=123

this.getEmployee = function (employeeID) {
    var response = $http({
        method: "post",
        url: "Home/getEmployeeByNo",
        params: {
            EmpNo: employeeID //changed to `EmpNo`
        }
    });
    return response;
}

还可以从

$scope

传递

employeeID

，如like

myService.getEmployee（$scope.employeeID）中所述
你从功能测试中得到了什么？@neela将此答案标记为正确，如果有帮助，谢谢；）
