I use routeProvider to define controlers and templates for my urls.
When I click on the link, which has the same url as is the actual location, nothing happens. I would like the reload() method to be called if a user clicks on such a link even if the location hasn't changed. In other words, if I set the location to the same value, I would like it to behave the same as if I would set it to different value.
Is there a way to configure routeProvider or locationProvider to do it automatically? Or what is the right approach to do this? This is stadard behaviour in round trip applications, but how to do it in angularjs?
I've asked it on google groups as well.
UPDATE:
This question is getting lots of views, so I will try to explain how I solved my problem.
I created a custom directive for linking in my app as Renan Tomal Fernandes suggested in comments.
angular.module('core.directives').directive('diHref', ['$location', '$route',
function($location, $route) {
return function(scope, element, attrs) {
scope.$watch('diHref', function() {
if(attrs.diHref) {
element.attr('href', attrs.diHref);
element.bind('click', function(event) {
scope.$apply(function(){
if($location.path() == attrs.diHref) $route.reload();
});
});
}
});
}
}]);
The directive is then used for all links in my app I want to have this functionality.
<a di-href="/home/">Home</a>
What this directive does is that it sets the href attribute for you based on di-href attribute so angular can handle it like always and you can see the url when you hover over the link. Furthermore when user clicks on it and the link's path is the same as the current path it reloads the route.
Add a / (slash) to the defined url in the route configuration
I met a similar problem today, I have a link in my web page and when I click it, I want the ng-view reload each time, so that I can refresh data from server. But if the url location doesn't change, angular doesn't reload the ng-view.
Finally, i found a solution to this problem. In my web page, I set the link href to:
test
But in the route config, I set:
$routeProvider.when('/test/', {
controller: MyController,
templateUrl:'/static/test.html'
});
The different is the last slash in url. When I click href="#/test" for the first time, angular redirect the url to #/test/, and load ng-view. when i click it second time, because the current url is #/test/, it's not equal to the url in the link (href="#/test") I clicked, so Angular triggers the location change method and reloads the ng-view, in addition Angular redirects the url to #/test/ again. next time i click the url, angular does the same thing again. Which is exactly what I wanted.
Hope this was useful for you.
You can add a _target='_self' on the link to forces the page to reload.
e.g.
{{customer.Name}}
Tested with version 1.0.5 and 1.2.15 on IE and Firefox.
Here's more information from AngularJS site :
Html link rewriting
When you use HTML5 history API mode, you will need different links in different browsers, but all you have to do is specify regular URL links, such as:
link
When a user clicks on this link,
In a legacy browser, the URL changes to /index.html#!/some?foo=bar
In a modern browser, the URL changes to /some?foo=bar
In cases like the following, links are not rewritten; instead, the browser will perform a full page reload to the original link.
Links that contain target element
Example: link
Absolute links that go to a different domain
Example: link
Links starting with '/' that lead to a different base path when base is defined
Example: link
you should use $route.reload() to force the reload.
I don't know if is there a 'automatic' way to do this, but you can use ng-click on these links
For people who are using AngularUI Router. You can use something like this:
<a data-ui-sref="some.state" data-ui-sref-opts="{reload: true}">State</a>
Notice the reload option.
Found the answer here: https://stackoverflow.com/a/29384813/426840
From #Renan Tomal Fernandes answer. following is an example
HTML
<a href="#/something" my-refresh></a>
JS
angular.module("myModule",[]).
directive('myRefresh',function($location,$route){
return function(scope, element, attrs) {
element.bind('click',function(){
if(element[0] && element[0].href && element[0].href === $location.absUrl()){
$route.reload();
}
});
}
});
I think it's a simpler approach.
.directive ('a', function ($route, $location) {
var d = {};
d.restrict = 'E';
d.link = function (scope, elem, attrs) {
// has target
if ('target' in attrs) return;
// doesn't have href
if (!('href' in attrs)) return;
// href is not the current path
var href = elem [0].href;
elem.bind ('click', function () {
if (href !== $location.absUrl ()) return;
$route.reload ();
});
};
return d;
});
Assuming You want to make all basic <a> links (without target attribute) reload on click and You use relative links in the href attribute (e.g. /home instead of http://example.com/home) You don't have to add any special markup to your HTML (comes handy when updating a site with HTML already written).
In my case if the url is same, nothing worked including $route.reload(), $location.path(), $state.transitonTo() etc.
So my approach was Using Dummy Page as follows,
if( oldLocation === newLocation ) {
// nothing worked ------------
// window.location.reload(); it refresh the whole page
// $route.reload();
// $state.go($state.$current, null, { reload: true });
// $state.transitionTo($state.current, $stateParams, {reload:true, inherit: false, notify: false } );
// except this one
$location.path('/dummy');
$location.path($location.path());
$scope.$apply();
}
You need to make '/dummy' module somewhere, the module doesn't do anything, it only change url so that next $location.path() can be
applied. Don't miss $scope.$apply()
I ran into this issue a moment ago, except for it was the home page '/'. I wanted a simple solution with less code. I just took advantage of the .otherwise method in the $routProvider
So in the html link looks like:
Home
since there is no '/home' page specified in the routProvider it will redirect to '/' via the 'otherwise' method. page with this set up:
.otherwise({
redirectTo: '/'
});
Hope it helps someone
I tried Wittaya's solution above using directive approach. Somehow the directive keeps throwing error. I end up with this solution
HTML
Devices
Controller
$scope.stateGo = function (stateName) {
if ($state.$current.name === stateName) {
$state.reload();
} else {
$state.go(stateName);
}
}
Just tried adding this
$(window).on('popstate', function(event) {
//refresh server data
});
and it works fine

I have started building a website using Angular, and have started to use ui-router along with ngAnimation for some sick animations! All was going well until I started adding external resources such as Facebook's Page Widget (https://developers.facebook.com/docs/plugins/page-plugin) and Google Maps API for some custom map styles.
The Issue
I have the Facebook widget on the home page, and it loads fine when you first access the URL as can be seen below (Have to block the name of client, totally not just bad design...):
Once I click on another page to load it in (using ui-view to dynamically bring in a view), for example contact view and go back to the home page (where the code is to display the widget), the widget will no longer load but will load the basic header tag that Facebook provide as can be seen below:
This also happens on the contact page when loading in Google Maps API. If I click on the contact page, there will just be a large white area on where the map should be, but if you had to actually refresh the page the map will load.
I am assuming that the issue is that the website is not able to send a request to either Facebook or Google when a view is loaded in, but can only happen when the page is actually refreshed or a new page load.
My Code
Okay so I'll explain the basics of how my application works along with code. I am rather new with Angular so if I have terrible code, please let me know.
Structure
This is a screen shot of my web apps structure. The main template file is index.html, and any view are within the views directory, which are loaded in using ui-router.
Main Angular applications code (app.js)
var app = angular.module('bmApp', ['ngAnimate', 'ui.router', 'ui.bootstrap'])
.config(function($stateProvider, $urlRouterProvider) {
$stateProvider
.state('header', {
templateUrl: './assets/views/template.html',
})
.state('header.home', {
url: '/',
templateUrl: './assets/views/home.html',
controller: "HomeController"
})
.state('header.about', {
url: '/about',
templateUrl: './assets/views/about.html',
controller: "AboutController"
})
.state('header.work', {
url: '/work',
templateUrl: './assets/views/work.html',
controller: "WorkController"
})
.state('header.services', {
url: '/services',
templateUrl: './assets/views/services.html',
controller: "ServicesController"
})
.state('header.contact', {
url: '/contact',
templateUrl: './assets/views/contact.html',
controller: "ContactController"
});
$urlRouterProvider.otherwise('/'); //if no views are matched, just redirect back to home page.
})
I am using nested views to keep the header of the website static (not changing) and then loading in views under the header, with ngAnimate to make it look cool.
In my main template, index.html, I have a simple <div ui-view></div> to load in the view that is requested. I also have the required script to request Facebook's API just after the . My controllers do not actually currently have anything in them. I did have some vanilla JavaScript in some, but do not currently need it anymore. I also tried to wrap the code provided by Facebook in a function, and call it within the controller for the specific view but that just had the same results of having it within the body on the template (index.html) page.
Pulling my hair out at this, can't seem to find a solution. I hope I have explained my issue without missing out on anything. I appreciate any help you could give, would be so awesome.
Edit: I should have probably mentioned that my main template is index.html, I then inject the view in to /views/template.html AND THEN inject it into index.html. Not too sure if this is best practice, but felt like it would work well (I don't think that is the issue).
I will give you only half of an answer, but maybe it will point you to right direction. I also struggled with Google API in SPA application once. I had the same issue - after entering the contact page, a white box appeared instead of map. The solution turned out to be simple - I just needed to force map reload, when I entered contact sheet. This function was attached as onclick event to contact page link:
function reloadGoogleMap() {
if (counter == 0) {
document.getElementById('google-map').src += '';
counter++;
}
}
I used the counter to make sure it happens only once - you won't need it probably. With Angular, you might need to make sure the reload happens after element is rendered. Maybe a simple directive would work, however I didn't test that:
angular.module('your_directives_module')
.directive('mapLoaded', [mapLoadedDirective]);
function mapLoadedDirective() {
return {
restrict: 'A',
link: function (scope, elem, attrs) {
elem.on('load', function (event) {
// Force reload
elem.src += '';
});
}
};
}
It could be used like:
<!-- Div/iframe with google map -->
<div map-loaded></div>
Maybe Facebook API also has some simple way which you could use to force widget reload when the partial view is loaded, however I've never tried to use that with Angular.
Don't you have to wrap it in a $rootScope.$apply function in order to update your view?
$rootScope.$apply(function () {
// some code
});
I am using, Angular.js 1.3, with ui-router.
I have 3 pages, page1.html, page2.html, page3.html.
When user click on page1, page2 will open, but I want to save the scroll state of page 1, where user was before clicking, so that after clicking on back button he lands on same scroll state.
To solve this I opened the page2.html over the page1.html, in iframe, and giving it absolute position to display over the page1.html, and I am using the:
history.pushState({}, '', '/page2.html');
to change the url. This implementation working fine.
Now when user click on link on page2.html, it should open the page3.html, like a normal link, for which I used :
$state.go("page3")
The problem is now the state chages, and page3.html loads, but url is still the /page2.html, url is not changing.
I even tried:
history.pushState({}, '', '/page3.html');
Still url is not changing. Anyone know why it's happening.
Even though the solution you are trying to implement is very creative, I would really choose another direction.
You've got various option, all of which rely on caching the scroll position somewhere. For example:
var scrollTopData = {};
function changeState (toState) {
var currentStateName = $state.current.name;
scrollTopData[currentStateName] = window.scrollY;
$state.go(toState);
}
Then the question remains what to do with the scroll position you have cached. $state.go returns a promise, so a solution would be:
var scrollTopData = {};
function changeState (toState) {
var currentStateName = $state.current.name;
scrollTopData[currentStateName] = window.scrollY;
$state.go(toState).then(function () {
if (toState in scrollTopData) {
window.scrollTo(0, scrollTopData[toState]);
}
});
}
Depending on your implementation, you could also use the answer of asgoth:
I haven't used it before, but angular has a $anchorScroll service. As to reloading the data, you could cache it using $cacheFactory, or store the data on a higher scope.
Another solution would be to use a stateChangeEvent. For example:
$rootScope.$on('$stateChangeSuccess',
function (event, toState, toParams, fromState, fromParams) {
// Do magic
}
);
My advice would be to use the promise returned by $state.go.
You can not have a change in url if you change the default behavior of angular. The part in url after hash changes automatically. You do not have changing urls because you force the browser to /somepage.html
try some thing like /#somepage.html
note the hash(#) added here.
From my AngularJS Home Page I need to scroll to an anchor tag in another page. Both these pages are coming as partial html's into the ng-view component, based on the url. On starting the server, the home page is loaded and from there in need to go to the faq page. I used the normal href with #, but that didn't point to the correct div in the target page. Here is what I tried with $anchorScroll
Here is the controller method
$scope.scrollToFaq = function(id) {
$location.path("/faq")
$location.hash(id);
$anchorScroll();
}
Here is how I use it in the home.html
<a ng-click="scrollToFaq('HERE')" href="" class="link">Here</a>
But this is not working properly. If I load the faq page directly and then come back and click the anchor link from the home page, it works. Is it possible to do this with `$anchorScroll
Try to use Angular's $timeout service.
$scope.scrollToFaq = function(id) {
$location.path("/faq");
$timeout(function(){
$location.hash(id);
$anchorScroll();
}, delay);
here delay would be the time you would like to wait until the anchor scroll happens. I have read about 300ms / 400 ms working for people. When I had this issue, I just had to call the $anchorscroll inside the $timeout. So use what's best for you case.
Note: I am on the lookout for a solution without the use of $timeout. Will update when I find one.
Sounds like a history related issue. If the div has already been loaded once it is found immediatly. This solution worked for me in the past. Maybe an idea to wait for the page to load.
$scope.scrollToFaq = function(id) {
$location.path("/faq");
$(window).on("load", function(){
$location.hash(id);
$anchorScroll();
});
};
Had the same problem. But fixed it :)
Idea is to change to the URL, wait a halfsecond and than jump to the anchor.
HTML:
Links
Controller:
angular.module('exampleApp').controller('NavbarCtrl', function ($scope, $location, $timeout, $anchorScroll) {
$scope.goToAnchor = function(path, anchor){
$location.path('/');
$timeout(function() {
$anchorScroll(anchor);
}, 500);
};
});
I want to do a custom modal asking if user wants to save changes before leaving a page, using ui.bootstrap.
I'm not using angular route configuration (so i guess i can't use '$locationChangeStart'or '$routeChangeStart').
I can't use window.onbeforeunload as you can't custom the popup window ( apart maybe from the messages displayed ).
Any idea ?
Thank you,
Add a directive, something similar to this:
app.directive('a', function() {
return {
restrict: 'E',
link: function(scope, el) {
$(el).click(function(e) {
e.preventDefault()
alert('Do your modal stuff here');
});
}
}
});
Here is a working example. You can pass the href to the modal, and if they click through, you can use the href to redirect the page to their final destination.
I have an app with angularjs routing, but on some view i want to scroll to some specific div and i use anchorScroll but sometimes (not all times) it refresh all page even i stop event propagation.
Did anyone had this issue?
$scope.redirectTodiv = function(divname,event) {
event.stopPropagation();
event.preventDefault();
$location.hash(divname);
$anchorScroll();
};
Try like this
$scope.redirectTodiv = function(divname,event) {
var id = $location.hash();
$location.hash(divname);
$anchorScroll();
$location.hash(id);
};
The way to ensure navigation with one click is to combine $location.hash() $anchorScroll and setting routeProvider reloadOnSearch property to false i.e.
In your controller code:
$location.hash("editor");
$anchorScroll();
In your route provider:
$routeProvider.when("/masters/voucher", {
templateUrl: "views/card/voucher.html",
reloadOnSearch: false
})
I've two use cases on the same page :
When clicking save, if the response is an error, scroll to the errorDiv that displays the error to the user.
David Kabii's answer did work for me.
However, on the load of the page, in the controller, I want to scroll to a specific area of the page where the user's input is expected. This wouldn't work. I had to use window.setTimeout to workaround this. (there's probably a better way)
window.setTimeout(function(){
$location.hash("anchorForm");
$anchorScroll();
}, 300);
