在页面刷新时将用户数据存储到初始化rootScope

var app = angular.module('app', ['ngStorage']);

app.controller('myController', function($scope, $rootScope, $localStorage) {
  // 在控制器中初始化rootScope
  $rootScope.userData = {};

  // 在页面刷新时，将用户数据存储到本地存储中
  window.onbeforeunload = function() {
    $localStorage.userData = $rootScope.userData;
  };

  // 在页面加载时，从本地存储中恢复用户数据
  angular.element(document).ready(function() {
    if ($localStorage.userData) {
      $rootScope.userData = $localStorage.userData;
    }
  });
});

<div ng-controller="myController">
  <input type="text" ng-model="userData.name" placeholder="Name">
  <input type="email" ng-model="userData.email" placeholder="Email">
  <!-- 其他用户数据字段 -->

  <button ng-click="saveUserData()">Save</button>
</div>

app.controller('myController', function($scope, $rootScope, $localStorage) {
  // 其他代码...

  // 保存用户数据到rootScope
  $scope.saveUserData = function() {
    $rootScope.userData = $scope.userData;
  };
});
