是否可以判断现在处于一个digest cycle中？直接用$rootScope.$$phase判断吗？我想判断如果没有处理轮询中就手动调用scope.$digest(),这个可以用$evalAsync解决吗？
$rootScope.$$phase
scope.$digest()
$evalAsync
闭关修行中......
目前AngularJS未提供公开的API判断，不过我翻了一下源码发现：ngModelDirective 指令写法中有这么一段
if ($rootScope.$$phase) { scope.$evalAsync(modelCtrl.$setTouched); } else { scope.$apply(modelCtrl.$setTouched); }
通过$rootScope.$$phase判断当前如果在digest循环中，调用scope.$evalAsync，不在则调用 scope.$apply
scope.$evalAsync
scope.$apply
