Any uncaught exception in Angular表达式s is delegated to this service. The default implementation simply delegates to$log.errorwhich logs it into the browser console.
In unit tests, ifangular-mocks.jsis loaded, this service is overridden by mock $exceptionHandler which aids in testing.
angular.module('exceptionOverride',[]).factory('$exceptionHandler',Function(){returnFunction(exception,cause){exception.message+=' (caused by "'+cause+'")';throwexception;};});This example will override the normal action of$exceptionHandler, to make angular exceptions fail hard when they happen, instead of just logging to the console.
$log$exceptionHandler(exception,[cause]);
