I need to resolve a service while routing to other state using State Provider in angular.
You can use resolve object in $stateProvider while routing to other state.
For Example :
resolve: {
resolvedTheme: ['ThemeService', function (ThemeService) {
return ThemeService.get();
}]
}
Here:
Resolve is a service name and this is returning a callback function.

I have 2 different angular controllers and one of it having broadcast like this
$timeout(function() {
if($scope.modal){
$rootScope.$broadcast(DATAINPUT_EVENT.REFRESH_COMPLETED_DATA_LIST,id);
$scope.modal.hide();
$scope.modal.remove();
}
}, 3000);
And in another controller I am catching broadcast.
$scope.$on(DATAINPUT_EVENT.REFRESH_COMPLETED_DATA_LIST,function(event,id){
// some action
});
Problem is $scope.$on function getting called 3 times. I have referred
AngularJs broadcast repeating execution too many times and
Angular - broadcast , $on called multiple times in directive
but could not get solution using them. Please help me out...!!
Quick and dirty hack: use a boolean flag
var once = true;
$timeout(function() {
if($scope.modal){
$rootScope.$broadcast(DATAINPUT_EVENT.REFRESH_COMPLETED_DATA_LIST, {id: id, once: once});
$scope.modal.hide();
$scope.modal.remove();
once = false;
}
}, 3000);
and in your listener:
$scope.$on(DATAINPUT_EVENT.REFRESH_COMPLETED_DATA_LIST,function(event,args){
if(args.once)
// some action, only the first time
});
Bear in mind this is (dirty, but still) solution only if you can't find why your broadcast it's called 3 times every event.
To fix issue for a moment, I did something like follows,
if(!$rootScope.$$listenerCount[DATAINPUT_EVENT.REFRESH_COMPLETED_DATA_LIST]){
$scope.$on(DATAINPUT_EVENT.REFRESH_COMPLETED_DATA_LIST,function(event,id){
// some action
});
}
But very soon I found I have initialized my controller multiple times and I have taken corrective actions to remove the multiple declarations of controller.

I'm watching this video tutorial on building an e-commerce site with Angular and Moltin. I've gotten to the 19 minute mark where he begins creating the product.html view.
I'm not sure why, but I can console.log(product) just fine, but when I try to use variables like {{ product.title} in my product.html view, it doesn't show. Plain text shows up fine, and in my category.html view I can get my categories to ng-repeat using {{ category.title }} just fine.
I am not sure why I can log the product object, but the view will not render it.
Here's a link to my GitHub repo. Any help is appreciated.
There is a scope conflict being caused because you are declaring product to be your controller with the controllerAs statement here, and then setting $scope.product in your controller here
You need to resolve this conflict by either renaming $scope.product to something else in the controller, or renaming your controllerAs: 'product' statement.
I was able to make this work by changing controllerAs:'product' to controllerAs:'prod', but any solution resolving the conflict between the variable names should work.
Could you provide any snippets or a fiddle of when you initialize products? Just from glancing at the video it seems that the promise from your ProductCtrl might not be fulfilled by the time you are invoking the console.log(); What value are you getting when you console.log()?
Also, although this doesn't seem to be the issue- I have seen the same issue when binding to primitive types!
A simple check could be trying to instantiate the product to an empty object: $scope.product = {}; somewhere in the same context BEFORE you are setting to new value- that way angular's magic will know to watch and bind that object in the digest cycle.

I started to look into Angular JS and find this framework great so far.
I have a question about form submission best practices though.
I have an update data form which has ng-controller and ng-submit directives, it loads data from the server using get on load and posts data on submit.
My question is when a user clicks submit button how do I indicate that something is actually happening? E.g. display activity indicator while the action is being processed and some kind of success or failure message after it was processed.
I used jQuery to do this for ajax forms before, do I still use jQuery or there are other tools for that in Angular JS I don't know about?
Thanks
Working with AJAX promises in angular is much straight forward. Have a look at this post. While your request is being processed, you could show a loading icon/text whatsoever:
$scope.loading = true;
$http.post("http://example.appspot.com/rest/app", {"foo":"bar"})
.success(function(data, status, headers, config) {
$scope.data = data;
$scope.loading = false;
}).error(function(data, status, headers, config) {
$scope.status = status;
$scope.loading = false;
});
Then just hide and show whatever indicates your loading status:
<p ng-show="loading">LOADING</p>

Having trouble trying to recompile angular app.
Is there a way to unbootstrap after calling angular.bootstrap?
Once I do angular.bootstrap when already bootstrapped, causes errors
Thanks!
It does not seem like angular was designed to do this, and I can't think of any good reason why you would want to (but maybe you do). That said, from looking at the angular.js source code
it seems like the only way that this could work would be to remove the element you originally bootstrapped from the DOM and then re-add it and then try bootstraping again.
Here's a jsfiddle proof of concept that bootstraps a super simple app and then after 5 seconds bootstraps itself again. I'd be extremely hesitant to do something like this on a complex app but it does seem to work.
var bootstrapApp = function(appDiv) {
var isSecondTime = false;
if (appDiv) {
document.body.removeChild(appDiv);
isSecondTime = true;
}
appDiv = document.createElement('div');
appDiv.id = "myApp";
appDiv.innerHTML = (isSecondTime ? ' 2nd bootstrap': ' 1st bootstrap') + template.innerHTML;
document.body.appendChild(appDiv);
angular.bootstrap(angular.element(appDiv), ['myApp']);
return appDiv;
}
var createdAppDiv = bootstrapApp(null);
setTimeout(function() {
console.log("try boostraping again");
bootstrapApp(createdAppDiv);
}, 5000);
