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 $exceptionHandler which aids in testing.
angular.module('exceptionOverride', []).factory('$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.
$log$exceptionHandler(exception, [cause]);
