Answer 1

<form>标记位于ng-app / ng-controller属性行之外。 Angular无法访问$ scope.add函数中的$ scope.userForm。

Answer 2

$scope.add= 
function(userForm   put form object)
{
        $scope.user={};
};

Answer 3

HTML更改：

<md-button class="md-raised md-primary" ng-click="add(userForm)">Signup</md-button>

角度变化：

$scope.add=function(userForm){
        $scope.user={};
        userForm.$setPristine();
        userForm.$setUntouched();
    };

userForm不在$ scope中，您需要传递给添加功能。

Answer 4

您的表单标记位于HTML控制器之外

在控制器范围之外，所以请使用此

<div ng-app="myApp" ng-controller="myCtrl">
<form name="userForm" novalidate role="form" ng-submit="userForm.$valid && userlist(user)">
    <div  layout="column" layout-align="center center">
        <md-card>
            <div layout-gt-sm="row">
                <md-input-container class="md-block" >
                    <label>First Name</label><input name="firstname" ng-model="user.firstname" required>
                    <div ng-show="userForm.$submitted || form.firstname.$touched">

          <div ng-show="userForm.firstname.$error.required">your first Name.</div>

        </div>

                </md-input-container>
                <md-input-container class="md-block" >
                    <label>Last Name</label><input name="lastname" ng-model="user.lastname" required>
                    <div ng-show="userForm.$submitted || form.lastname.$touched" >
                        <div ng-show="userForm.lastname.$error.required">Enter last name</div>
                    </div>
                </md-input-container>
            </div>
            <md-input-container>
                <label>DOB</label>
                <md-datepicker ng-model="user.dateofbirth" name="dateofbirth" required></md-datepicker>
                <div ng-show="userForm.$submitted || form.dateofbirth.$touched ">
                    <div ng-show="userForm.dateofbirth.$error.required">Enter DOB</div>
                </div>
            </md-input-container>
            <md-input-container class="md-block"  >
                <label>Email</label><input name="mail" type="email" ng-model="user.mail" required>
                <div ng-show="userForm.$submitted || form.mail.$touched">
                    <div ng-show="userForm.mail.$error.required">Enter email ID</div>
                </div>
            </md-input-container>
            <md-input-container class="md-block"  >
                <label>Password</label><input name="paswd" type="Password" ng-model="user.paswd" required>
                <div ng-show="userForm.$submitted || form.paswd.$touched">
                    <div ng-show="userForm.paswd.$error.required">Enter your password</div>
                </div>

                <div ng-show="userForm.$submitted || form.paswdtwo.$touched">

                </div>
            </md-input-container>
            <md-card-action layout="row" layout-align="center">
            <md-button class="md-raised md-primary" ng-click="add()">Signup</md-button>

            </md-card-action><md-card-content>
            <span ng-repeat="x in lag">
            <span ng-bind="x.firstname" ></span>
            </span>
            </md-card-content>
        </md-card>  
    </div>
</form>
