    getCurrentPosition: cordovaReady(function (onSuccess, onError, options) {

        navigator.geolocation.getCurrentPosition(function () {
            var that = this,
                args = arguments;

            if (onSuccess) {
                $rootScope.$apply(function () {
                    onSuccess.apply(that, args);
                });
            }
        }, function () {
            var that = this,
                args = arguments;
            if (onError) {
                $rootScope.$apply(function () {
                    onError.apply(that, args);
                });
            }
        }, {
            enableHighAccuracy: true,
            timeout: 20000,
            maximumAge: 18000000
        });
    })

奇怪的事情，在我的LG4X它工作正常，但在我的三星S2它抛出上述错误。任何想法什么错？

Strange thing, on my LG4X it works fine, however on my samsung s2 it throws the above error. Any ideas whats wrong?

推荐答案

由于您呼叫 $适用现有的消化周期内，您收到此错误。

You are getting this error because you are calling $apply inside an existing digestion cycle.

最大的问题是：你为什么叫 $适用？你不应该在任何时候需要调用 $适用除非你是从非角事件的接口。 $的存在适用通常意味着我做错了什么（除非再次，$应用从非角事件发生）。

The big question is: why are you calling $apply? You shouldn't ever need to call $apply unless you are interfacing from a non-Angular event. The existence of $apply usually means I am doing something wrong (unless, again, the $apply happens from a non-Angular event).

如果 $适用真的是适当这里，可以考虑使用一个安全适用的方法：

If $apply really is appropriate here, consider using a "safe apply" approach:
