AngularJS检索数据并显示ng-change

Question

我有一个向数据库添加记录的功能。 我需要做的是当我选择一个选项时，所有必填字段都必须填充数据。

我是angularjs的新手，想学习如何做到这一点。

下面是我的代码。

模板

 <div class="col-md-10">
      <div class="col-md-12">
        <div class="form-group">
            <label>Select Employee </label>
            <select class="form-control" ng-change='getData()'  id='empId' ng-model="empId"  ng-options="opt.id as opt.value for opt in employees">
            </select>
        </div>
      </div> 

      <div class="col-md-6">
        <div class="form-group">

          <select class="form-control" ng-change ="getPos()" ng-model="data.Employee.departmentId" ng-options="opt.id as opt.value for opt in deparments"  data-validation-engine="validate[required]">

        </div>
      </div> 

      <div class="col-md-6">
        <div class="form-group">

           <select class="form-control"  ng-model="data.Employee.positionId" data-validation-engine="validate[required]">
           </select>
        </div>
      </div> 

      <div class="col-md-6">

          <input type="text" class="form-control" ng-model="data.Employee.rate" data-validation-engine="validate[required]">
        </div>
      </div> 

      <div class="col-md-6">

          </div>
        </div>
    </div>

控制器

 app.controller('LoanAddController', function($scope, Loan,Select) {
 $('#form').validationEngine('attach');

 $scope.load = function() {
  Loan.get({ id: $scope.employeeId }, function(e) {
  $scope.data = e.data;
 });

 Select.get({ code: 'departments' }, function(e) {
 $scope.departments = e.data;
 });

// employees selection
 Select.get({ code: 'employees' }, function(e) {
 $scope.employees = e.data;
 });

  Select.get({ code: 'positions' }, function(e) {
  $scope.positions = e.data;
  });
 }


 $('#dateStart').datepicker({
   format: 'mm/dd/yyyy',
   autoclose: true
 });

 $scope.load();
 // save loan data
 $scope.save = function() {
  valid = $("#form").validationEngine('validate');

   if (valid) {
      Loan.save($scope.data, function(e) {
        if (e.ok) {
         $.gritter.add({
         title: 'Successful!',
         text:  e.msg,
      });
      window.location = '#/loans';
    } else {
      $.gritter.add({
        title: 'Warning!',
        text:  e.msg,
      });
     }
    });
   }
  }
 });

一些JSON数据

我必须在字段中填写员工详细信息。 任何帮助将不胜感激。

谢谢你们，
