如何使用AngularJS和show message在提交后清除表单数据？

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.7.9/angular.min.js"></script>

<div ng-app="myApp" ng-controller="myCtrl">
  <!-- 表单内容 -->
</div>

<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
  $scope.formData = {}; // 表单数据对象

  $scope.submitForm = function() {
    // 提交表单的逻辑

    // 清除表单数据
    $scope.formData = {};

    // 显示提交成功的消息
    $scope.showMessage = true;
  };
});
</script>

<div ng-app="myApp" ng-controller="myCtrl">
  <form ng-submit="submitForm()">
    <!-- 表单内容 -->

    <button type="submit">提交</button>
  </form>

  <div ng-show="showMessage">
    提交成功！
  </div>
</div>
