angularjs $ scope。$ apply（）给出了这个错误：错误：[$ rootScope：inprog]

I'm trying to update some texts on a page that is part of $scope. But I keep getting this error:

我正在尝试更新作为$ scope一部分的页面上的一些文本。但我一直收到这个错误：

Error: [$rootScope:inprog] [http://errors.angularjs.org/1.2.15/$rootScope/inprog?p0=%24apply][1]

Obviously I'm doing something wrong. :) Any ideas of how I can fix this? I want the page to update to the new variables in the scope.

显然我做错了。 :)关于如何解决这个问题的任何想法？我希望页面更新到范围中的新变量。

This is the code I'm using for updating:

这是我用于更新的代码：

medicalApp.controller('MainCtrl', function($scope, $cookies, getTranslation) {
    getTranslation.get(function(data){
        $scope.translation = data;
    });

    $scope.changeLang = function (lang) {
        console.log(lang);
        $cookies.lang = lang;
        $scope.$apply(function(){
            getTranslation.get(function(data){
                $scope.translation = data;
                console.log(JSON.stringify($scope.translation));
            });
        });
    };
});

the html:

html：

<body ng-controller="MainCtrl">
    ...
            <div class="header-lang col-xs-4">
                <p>
                    <a href="#" ng-click="changeLang('de')">DE</a> | 
                    <a href="#" ng-click="changeLang('fr')">FR</a></p>
            <div>{{ translation.text }}</div>  <---- Example variable I want updated.
    ...

I'm also using ngRoute with separate controllers for each page I load, if that has anything todo with it?

我也在为我加载的每个页面使用ngRoute和单独的控制器，如果它有任何东西吗？

3 个解决方案

#1

You are using $scope.$apply(...) inside the function changeLang so you are getting the common 'already in a digest' error. You don't need to put the call to getTranslation inside a $scope.$apply(...) block because ng-click already has you taken care of. Yank that out and it should just work. Also, I'd recommend running with a non-minified version of angular for dev so you can see better errors in your console.

你在函数changeLang中使用$ scope。$ apply（...），这样你就会得到常见的“已经在摘要中”的错误。你不需要在$ scope。$ apply（...）块中调用getTranslation，因为ng-click已经由你处理了。突然说，它应该工作。另外，我建议使用非缩小版本的angular for dev，这样你就可以在控制台中看到更好的错误。

If your template don't change after changing models and you need using $scope.$apply, You can use $scope.$applyAsync instead of this.

如果您的模板在更改模型后没有更改，并且您需要使用$ scope。$ apply，您可以使用$ scope。$ applyAsync而不是此。

$evalAsync works great:

$ evalAsync效果很好：

$scope.$evalAsync(function() {
    // Code here
});

Or simply:

或者干脆：

$scope.$evalAsync();

See: https://docs.angularjs.org/api/ng/type/$rootScope.Scope#$evalAsync
