javascript - 如何在非点击事件触发时停止重定向到页面

我正在尝试使用 Angular JS 开发一个单页 Web 应用程序。现在，当我单击 AddFilm 按钮时，它会重定向到 AddNewFilm.html，其中将显示一条消息，并且按钮将隐藏在当前 View 中，对于路由，我使用了 $routeProvider，但问题是当我手动输入 url 时 http://localhost:8088/fms/#/AddNewFilm它显示消息和按钮。

我的问题是我们是否可以在 myApp.config 或 myApp.controller 中指定条件，以便仅在单击按钮时路由到 url。

Welcome.html 是

最佳答案

是的，您只需要重定向到主页，当 myCtrl 位置发生变化并且没有任何单击的按钮时:

myApp.controller('myCtrl', function($scope,$window,$location) 
{
    // watch for location changing
    $scope.$on('$locationChangeStart', function() {
        var d = $scope.action.buttonClicked;

        // if there isn't any clicked button
        if (!Object.keys(d).map(function(k) { return d[k]; }).some(angular.identity)) {
            // redirect to main page
            $location.url('/');
        }
    });

    ...
}

并且您不应在 when 语句中指定 myCtrl 作为 Controller 。这是错误的。
