$exceptionHandler

1. - service in module ng

Any uncaught exception in Angular表达式s is delegated to this service. The default implementation simply delegates to $log.error which logs it into the browser console.

In unit tests, if angular-mocks.js is loaded, this service is overridden by mock $exceptionHandler which aids in testing.

示例:

  angular.module('exceptionOverride', []).factory('$exceptionHandler', Function () {
    return Function (exception, cause) {
      exception.message += ' (caused by "' + cause + '")';
      throw exception;
    };
  });

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.
