Javascript 角度控制器不保存对象数据
代码运行良好，直到我决定将我的登录和注册表单移动到它自己的部分，现在在我登录之后，它确实重定向到partials/dashboard.html，但我的用户对象数据不再可访问。我在script.js中登录了console.log进行检查，对象确实得到了console，但是我无法在dashboard.html上访问它Javascript 角度控制器不保存对象数据,javascript,angularjs,mean-stack,mean,Javascript,Angularjs,Mean Stack,Mean,代码运行良好，直到我决定将我的登录和注册表单移动到它自己的部分，现在在我登录之后，它确实重定向到partials/dashboard.html，但我的用户对象数据不再可访问。我在script.js中登录了console.log进行检查，对象确实得到了console，但是我无法在dashboard.html上访问它 <div ng-controller="loginController"> <a href="#/dashboard">Dashboard

在loginController中设置本地存储中的数据后。它实际上在我的Chrome Javascript控制台中记录name字段。但是没有在dashboard.html登录页面中打印，并且dashboard页面使用相同的控制器但使用不同的实例。您需要将登录的用户对象存储在服务或本地存储中，并在需要时检索它
我建议您不要使用同一个控制器，因为它可能会让您感到困惑，而且从职责分离的角度来看也是如此。通过将数据设置为$rootScope而不是$scope来修复此问题 登录控制器
myapp.controller('loginController', function($scope, $rootScope, loginFactory, $localStorage, $sessionStorage, $location) {
$scope.getUser = function(){
console.log("Entered getUser controller")
var user_repack = {
email: $scope.user.email,
password: $scope.user.password
}
loginFactory.getUser(user_repack, function(data){
$location.path('/dashboard')
$rootScope.users = data
console.log($rootScope.users, "rootScope")
});
}
$scope.logout = function(){
console.log("Logged out");
for (var i in $rootScope) {
if (i.substring(0,1) !== '$') {
delete $rootScope[i];
}
}
$location.path('/')
}
})
我按照你的建议做了，用更新的代码编辑了原始帖子。分开控制器是更好的做法我同意，谢谢。但是仍然没有变化。同样的问题。您必须错误地使用服务。把它放在一个箱子里，我会让你知道的。已经上传到github上了，这有用吗？我公开了回购协议
