Html 启动警报框处于角度-空

我使用引导警报框显示成功消息。提交后带有消息的警报框显示得很完美，但问题是，提交前存在空警报框。Thnx。这是代码

$scope.resetPassword = function () {
        var data = {
            email: $scope.resetPasswordEmail
        };
        $http.post(serviceBase + 'aaaaaaaaaaaa', data).then(function (response) {
            $scope.successfullyReset = true;
            $scope.message = "Email has been send successfully, you will be redicted to login page in 5 seconds.";
            startTimer();
        }, function (response) {
            $scope.successfullyReset = false;
            $scope.message = "Failed to send mail. There is no user with requested email";

        });

    };

这里有html代码

<div data-ng-hide="message == ''" data-ng-class="(successfullyReset) ? 'alert alert-success' : 'alert alert-danger'">
            {{message}}
        </div><br />

{{message}}

这是图片，这是提交前的外观

警报框从不隐藏，因为您在回调中定义了变量

消息

，您应该在控制器的开头定义它

 $scope.message = '';

---

警告框永远不会隐藏，因为您在回调中定义了变量

message

，应该在控制器的开头定义它

 $scope.message = '';

声明

$scope.message第一个在
$http
块之外

 $scope.resetPassword = function () {
    var data = {
        email: $scope.resetPasswordEmail
    };

    $scope.message;

    $http.post(serviceBase + 'aaaaaaaaaaaa', data).then(function (response) {
        $scope.successfullyReset = true;
        $scope.message = "Email has been send successfully, you will be redicted to login page in 5 seconds.";
        startTimer();
    }, function (response) {
        $scope.successfullyReset = false;
        $scope.message = "Failed to send mail. There is no user with requested email";

    });

};
