到此代码 http://pastebin.com/B9V6yvFu

    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
        });
    })

$ b它抛出以上错误。

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

您收到此错误是因为您正在呼叫 $ apply 在现有的消化周期内。

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

最大的问题是：你为什么要调用 $ apply ？你不应该需要调用 $ apply ，除非你是从非角事件接口。存在 $ apply 通常意味着我做错了（除非，$ apply发生在非Angular事件）。

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 $ apply 真的适合这里，请考虑使用安全应用方法：

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