引用此代码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
        });
    })

奇怪的是，在我的 LG4X 上它运行良好，但是在我的 samsung s2 上它抛出了上述错误.有什么想法有什么问题吗?

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在现有消化循环内调用 $apply.

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?除非您从非 Angular 事件接口，否则您永远不需要调用 $apply.$apply 的存在通常意味着我做错了什么(除非再次发生 $apply 来自非 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 在这里确实合适，请考虑使用安全应用"方法:

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