Now my task is to rewrite $exceptionHandler provider so that it will output modal dialog with message and stop default event.
What I do:
in project init I use method .provider:
.provider('$exceptionHandler', function(){
//and here I would like to have rootScope to make event broadcast
})
standart inject method does not work.
UPD: sandbox - http://jsfiddle.net/STEVER/PYpdM/
You can inject the injector and lookup the $rootScope.
Demo plunkr: http://plnkr.co/edit/0hpTkXx5WkvKN3Wn5EmY?p=preview
myApp.factory('$exceptionHandler',function($injector){
return function(exception, cause){
var rScope = $injector.get('$rootScope');
if(rScope){
rScope.$broadcast('exception',exception, cause);
}
};
})
Update: add .provider technique too:
app.provider('$exceptionHandler', function() {
// In the provider function, you cannot inject any
// service or factory. This can only be done at the
// "$get" method.
this.$get = function($injector) {
return function(exception,cause){
var rScope = $injector.get('$rootScope');
rScope.$broadcast('exception',exception, cause);
}
};
});
My way of doing this - using a decorator and reverting to the previous exception handler on unknown errors:
app.config(function ($provide) {
$provide.decorator('$exceptionHandler', function($delegate, $injector) {
return function (exception, cause) {
if (ICanHandleThisError) {
var rootScope= $injector.get('$rootScope');
// do something (can use rootScope)
} else
$delegate(exception, cause);
};
});
});
You need to inject the $rootScope:
.provider('$exceptionHandler', '$rootScope', function(){
//and here I would like to have rootScope to make event broadcast
})
Is this what you tried? And if so do you have an error message or a jsfillde/plnkr to see why it failed?
