I'm new in AngularJS Community and I'm developping my first app with this Framework.
I created a new controller with this code :
.controller('AccountCtrl', function($scope, $location) {
alert('test');
})
And my route :
.state('app.account', {
url: "/account",
views: {
'menuContent': {
templateUrl: "templates/account.html",
controller: 'AccountCtrl'
}
}
})
The alert popup is shown the first time I access to the controller. But, if I change URL and I come back to AccountCtrl (with a classic html a), the alert popup is not shown again.
Could somebody explain to me why ?
Thanx for your help !
In Ionic Framework views and controllers will be cached by default. You ma add a listener to the views scope to receive a notification when the view is re-active again. For more information see: http://ionicframework.com/docs/api/directive/ionView/
and http://ionicframework.com/docs/api/directive/ionNavView/
You may also disable the cache on a view <ion-view cache-view="false">
.controller('AccountCtrl', function($scope, $location) {
$scope.$on('$ionicView.beforeEnter', function () {
// update campaigns everytime the view becomes active
// (on first time added to DOM and after the view becomes active after cached
alert('test');
});
})`
to reload Controller each time in ui router, use reload: true option on the .state
$stateProvider
.state('app.account', {
url: "/account",
reload: true //forcefully reload route and load controller again
})
I want to reload the controller I'm linking to in a menu in an ionic angular app. How do I declare the link in the markup so that it refreshes the destination route every time the link is clicked?
I saw this bit of code
$state.go($state.current, {}, {reload: true});
Which I suppose I can wrap in a controller method but I would prefer to do it in the markup if possible.
Wrap it in a function in your controller:
$scope.reload = function () {
$state.go($state.current, {}, { reload: true });
}
Then use it in your view:
<button ng-click="reload()">Reload</button>
I have an AngularJS app starting at index.html and using ui-router. Based on a trigger I want to reload the complete page. I tried:
$state.go($state.current, $stateParams, {
reload: true,
inherit: false,
notify: true
});
But that does not work. It doesn't reload my initial index.html.
I can do:
window.location.href = "index.html";
But then I'm on my initial page, not the current state.
Should a set window.location.href to index.html with query string parameters specifying current location? If I do that, how can I navigate to this location?
The current trick is:
$state.go($state.current.name, $state.params, { reload: true });
Everybody seems to have ignored what Serge van den Oever appears to actually be asking, and that's that he wants entire page to reload, and not just the route.
The solution for that is pretty simple if you inject the $window service into your controller:
$window.location.reload();
If you just want the route to reload (which seems to be much more common), and are using ui-router, then just inject the $state service and do:
$state.reload();
This should reinitialize controllers now that the bug has been fixed, although I don't think it reinitializes resolves.
This worked for me in a similar scenario.
$state.go('root.state').then(function(){
$state.reload();
});
If you include the $route service in your controller you could try $route.reload();
Try this:
$state.transitionTo($state.current, $stateParams, {
reload: true,
inherit: false,
notify: true
});
My app uses $state.go when switching between tabs and this cause to re-initializes the controllers and scope variable in those controllers get updated and causes memory leaks. Is there a way to stop re-initializing the controllers but change URL on state change?
Example below is routes.js in my app.
.state('home',
{
abstract : true,
url : '/home',
templateUrl : 'scripts/home.html'
})
.state('home.summary',
{
url : '/summary?userId',
controller : 'SummaryCtrl',
views :
{
summary:
{
templateUrl: 'scripts/home/summary.html'
}
}
})
.state('home.summary.detail',
{
url : '/detail/:id',
controller : 'DetailCtrl',
views :
{
detail:
{
templateUrl: 'scripts/home/detail.html'
}
}
})
How to stop reloading DetailCtrl but change URL when going to state home.summary.detail if the DetailCtrl is already loaded for unique id???
Also tried to $q.reject in resolve of child state, it stops reload of controllers but doesn't change url.
Also tried reloadOnSearch=false it stops reload of controllers but doesn't change url.
You can use $state.transitionTo instead of $state.go . $state.go calls $state.transitionTo internally but automatically sets options to { location: true, inherit: true, relative: $state.$current, notify: true } . You can call $state.transitionTo and set location: false . For example:
$state.go('.detail', {id: newId})
can be replaced by
$state.transitionTo ('.detail', {id: newId}, { location: false, inherit: true, relative: $state.$current, notify: true })
You can have a abstract controller that contain your memory leak code.
And a abstract controller will not update when url change.
Here is the doc from official github repo
https://github.com/angular-ui/ui-router/wiki/Nested-States-%26-Nested-Views
look at the Combination part.
here is the plnkr, contacts controller will only call once in this demo
contacts.detail controller will update every time you change state but share the scope with contacts controller

I'm using Angular UI Router and would like to reload the current state and refresh all data / re-run the controllers for the current state and it's parent.
I have 3 state levels: directory.organisations.details
directory.organisations contains a table with a list of organisations. Clicking on an item in the table loads directory.organisations.details with $StateParams passing the ID of the item. So in the details state I load the details for this item, edit them and then save data. All fine so far.
Now I need to reload this state and refresh all the data.
I have tried:
$state.transitionTo('directory.organisations');
Which goes to the parent state but doesn't reload the controller, I guess because the path hasn't changed. Ideally I just want to stay in the directory.organisations.details state and refresh all data in the parent too.
I have also tried:
$state.reload()
I have seen this on the API WIKI for $state.reload "(bug with controllers reinstantiating right now, fixing soon)."
Any help would be appreciated?
I found this to be the shortest working way to refresh with ui-router:
$state.go($state.current, {}, {reload: true}); //second parameter is for $stateParams
Update for newer versions:
$state.reload();
Which is an alias for:
$state.transitionTo($state.current, $stateParams, {
reload: true, inherit: false, notify: true
});
Documentation: https://angular-ui.github.io/ui-router/site/#/api/ui.router.state.$state#methods_reload
This solution works in AngularJS V.1.2.2:
$state.transitionTo($state.current, $stateParams, {
reload: true,
inherit: false,
notify: true
});
That would be the final solution. (inspired by #Hollan_Risley's post)
'use strict';
angular.module('app')
.config(function($provide) {
$provide.decorator('$state', function($delegate, $stateParams) {
$delegate.forceReload = function() {
return $delegate.go($delegate.current, $stateParams, {
reload: true,
inherit: false,
notify: true
});
};
return $delegate;
});
});
Now, whenever you need to reload, simply call:
$state.forceReload();
for ionic framework
$state.transitionTo($state.current, $state.$current.params, { reload: true, inherit: true, notify: true });//reload
$stateProvider.
state('home', {
url: '/',
cache: false, //required
https://github.com/angular-ui/ui-router/issues/582
Probably the cleaner approach would be the following :
<a data-ui-sref="directory.organisations.details" data-ui-sref-opts="{reload: true}">Details State</a>
We can reload the state from the HTML only.
#Holland Risley 's answer is now available as an api in latest ui-router.
$state.reload();
A method that force reloads the current state. All resolves are
re-resolved, controllers reinstantiated, and events re-fired.
http://angular-ui.github.io/ui-router/site/#/api/ui.router.state.$state
$state.go($state.current, $stateParams, {reload: true, inherit: false});
$scope.reloadstat = function () { $state.go($state.current, {}, {reload: true}); };
if you want to reload your entire page, like it seems, just inject $window into your controller and then call
$window.location.href = '/';
but if you only want to reload your current view, inject $scope, $state and $stateParams (the latter just in case you need to have some parameters change in this upcoming reload, something like your page number), then call this within any controller method:
$stateParams.page = 1;
$state.reload();
AngularJS v1.3.15
angular-ui-router v0.2.15
Silly workaround that always works.
$state.go("otherState").then(function(){
$state.go("wantedState")
});
For angular v1.2.26, none of the above works. An ng-click that calls the above methods will have to be clicked twice in order to make the state reload.
So I ended up emulating 2 clicks using $timeout.
$provide.decorator('$state',
["$delegate", "$stateParams", '$timeout', function ($delegate, $stateParams, $timeout) {
$delegate.forceReload = function () {
var reload = function () {
$delegate.transitionTo($delegate.current, angular.copy($stateParams), {
reload: true,
inherit: true,
notify: true
})
};
reload();
$timeout(reload, 100);
};
return $delegate;
}]);
Everything failed for me. Only thing that worked...is adding cache-view="false" into the view which I want to reload when going to it.
from this issue https://github.com/angular-ui/ui-router/issues/582
Not sure why none of these seemed to work for me; the one that finally did it was:
$state.reload($state.current.name);
This was with Angular 1.4.0
I had multiple nested views and the goal was to reload only one with content.
I tried different approaches but the only thing that worked for me is:
//to reload
$stateParams.reload = !$stateParams.reload; //flip value of reload param
$state.go($state.current, $stateParams);
//state config
$stateProvider
.state('app.dashboard', {
url: '/',
templateUrl: 'app/components/dashboard/dashboard.tmpl.html',
controller: 'DashboardController',
controllerAs: 'vm',
params: {reload: false} //add reload param to a view you want to reload
});
In this case only needed view would be reloaded and caching would still work.
I know there have been a bunch of answers but the best way I have found to do this without causing a full page refresh is to create a dummy parameter on the route that I want to refresh and then when I call the route I pass in a random number to the dummy paramter.
.state("coverage.check.response", {
params: { coverageResponse: null, coverageResponseId: 0, updater: 1 },
views: {
"coverageResponse": {
templateUrl: "/Scripts/app/coverage/templates/coverageResponse.html",
controller: "coverageResponseController",
controllerAs: "vm"
}
}
})
and then the call to that route
$state.go("coverage.check.response", { coverageResponse: coverage, updater: Math.floor(Math.random() * 100000) + 1 });
Works like a charm and handles the resolves.
You can use #Rohan answer https://stackoverflow.com/a/23609343/3297761
But if you want to make each controller reaload after a view change you can use
myApp.config(function($ionicConfigProvider) { $ionicConfigProvider.views.maxCache(0); ... }
If you are using ionic v1, the above solution won't work since ionic has enabled template caching as part of $ionicConfigProvider.
Work around for that is a bit hacky - you have to set cache to 0 in ionic.angular.js file:
$ionicConfigProvider.views.maxCache(0);
I had this problem it was wrecking my head, my routing is read from a JSON file and then fed into a directive. I could click on a ui-state but I couldn't reload the page. So a collegue of mine showed me a nice little trick for it.
Get your Data
In your apps config create a loading state
Save the state you want to go to in the rootscope.
Set your location to "/loading" in your app.run
In the loading controller resolve the routing promise and then set the location to your intended target.
This worked for me.
Hope it helps
