angular.js - About $apply()

Question

I keep getting errors after using $apply, please answer

Answer 1

This error is Digest Already In Progress。原因在于$digest循环已经在执行了，你再次手动调用了$applyfunction.

Just remove the redundant call, you can also $apply时判断是否已经在$digest:

javascriptif(!$scope.$$phase) {
    $scope.$apply();
}

Look at this question: http://stackoverflow.com/questions/12729122/prevent-error-digest-alrea...

If you don’t know what $digest is, refer to this article:
