AngularJs文本字段值未定义

Question

我有一个开始日期字段（日期选择器）和一个客户端状态（下拉列表）字段。

如果我在日期选择器中选择日期，则在将日期值传递给服务器时会显示undefined，但如果我在该字段中键入任何带日期的值，则该确切值将正确发送到服务器。

在下拉列表中，我没有得到它的值undefined。

我的代码是：

 <div class="form-group">
            <label for="inputPassword3" class="col-sm-3 control-label">Client Name</label>
            <div class="col-sm-9">
                <div ng-controller="MyCntrl"  >
                    <select class="form-control"  name="clientname" id="clientname" class="form-control" ng-model="vm.clientname" ng-change="change(myColor)" >
                        <option value="">Select Client Name</option>                                
                        <option ng-repeat="color in colors" 
                                value="{{color.value}}" 
                                ng-selected="{{color.value == myColor}}" name="clientname" id="clientname" class="form-control" ng-model="vm.clientname">
                          {{color.clientname}}
                        </option>
                    </select>
                </div>
            </div>
        </div>

 <div class="form-group">
            <label for="inputPassword3" class="col-sm-3 control-label">Project Startdate</label>
            <div class="col-sm-9">

            <!--   <input type="text" name="prjstartdate" id="prjstartdate" class="form-control" ng-model="vm.user.prjstartdate" required />-->
<div class="container" id="sandbox-container">
<div class="input-daterange input-group" id="datepicker" name="prjstartdate" id="prjstartdate" class="form-control" ng-model="vm.prjstartdate">
<input type="text" name="prjstartdate" id="prjstartdate" class="form-control" ng-model="vm.prjstartdate" required />

    </div>

</div>

 <div class="modal-footer" ng-controller="MyCntrlsave">      
          <div class="form-group">
            <div class="col-sm-offset-2 col-sm-10">         
                <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
                <button type="button" class="btn btn-primary" ng-click="savedetails()">Save changes</button>
            </div>
          </div>
      </div>

js code:

<script type="text/javascript">

    function MyCntrlsave($scope,$http) {

        $scope.savedetails = function() {
        var vm = this;
        var  projectname=$scope.vm.prjname;
        var  cilentname=$scope.vm.color;
        var clientstatus=$scope.vm.prjsta;
        var prjstartdate=$scope.vm.prjstartdate;
        var prjenddate=$scope.vm.prjenddate;
        var prjurl=$scope.vm.prjurl;
        alert("projectname::"+projectname)
        alert("prjstartdate::"+prjstartdate)

        }
        }
