I am working on a JS application using the Flux architecture. Among other things, the application displays a list of contacts and on each of them you can add or remove them from your contact book.
The application is doing optimistic UI updates, so in this case you can click on 'add' and see 'remove' right away while in the background we are doing the ajax request to add the contact.
However I do not know how to handle the case when someone clicks on 'remove' while we are still adding the contact. The 'remove' ajax request expects an ID that we do not have yet. It is also a requirement that I cannot grey out the 'remove' button while the request is running.
My ideal way I think would be to be able to dispatch actions that are dependent on other action. Is that a good idea, how can I implement that?... :/
Do you guys know how I should handle this case in a flux application architecture?
Optimistic updates are great -- but putting a "Remove" link that is incoherent makes no sense. Why not add the contact on the page but wait to add the "Remove" until you're notified by the store that the addition was successful?

Into an Universal windows app I want to check user's authentication during page load, or after that an user as navigated to. This permits me to offer a navigation filtered by authorizations with a single page granularity.
For example, if an user didn't login and a page requires authentication, user has to be redirected to a login page.
The problem comes when I try navigate to an other page from the OnNavigatedTo event, when previous navigation is not completed and the new fails. I've searched for other events like an OnNavigationCompleted, but I don't find anything. If I use an asynchronous method without waiting it works, as if I use a timer dispatcher, but both solutions doesn't sound like so clean.
Exists a method to handle an event raised after navigation completed or I have to pre-check authorization during navigation call? I hope to avoid this solution because a wrong call could show an unauthorized page.
If you really want a separate page according to this answer https://stackoverflow.com/a/19527979/4788286 you could probably use the loaded event. But I'd test it before just to make sure.
Sidenote: also, your question implies that you're doing business logic in the view codebehinds - this is bad practice, I suggest looking into the MVVM pattern. (If you need a framework I suggest MVVMLight or PRISM)
I think the precheck would be the best method. Check if they are authorized to view the page before they can navigate to the page. If they are not authorized ask if they want to log in or purchase rights to the page
Is there a way to create a page in ClickFunnels(https://www.clickfunnels.com/) website and when I submit that page, I need to store the form details in my rails app(into a particular table). Which means I want to display my database in the clickfunnels integrations list. I googled hours but couldn't get much information on this.
can anyone suggest me if you have done this. A reference link also much appreciated.
We couldn't find any way to do this inside clickfunnels itself, if there is a easy way to add custom systems to their integrations I too look forward to seeing those answers. Until then, here's what we did: We just put our custom form on their page and used ajax to send it back out the end point in our system it needed to hand that data too.
Then, since we also needed to submit the same info to click funnels, we build a fake CF form(I think we actually put one on the page, but used CSS to hide it, then filled it out dynamically from our custom form), and call submit on that form, sending the user through the normal click funnels submission process and sending them to the next page in the funnel.
As per my project requirement i want to develop an Ajax application with GWT Ui-Binder.. for achieving page refreshing automatically while getting content from database..
Remember: withOut click Refresh button (or) any mouse motion.If u aware about this task...can you please give me with any related exmaple..
if you want to refresh automatic, so you may have any condition where you get event of getting data from database like rpc came on success method etc.. then simply call Window.Location.refresh(); there.
I have an app with 3 sections:
Main menu;
Context Menu - Related to selected item in main menu;
and Page body - Related to selected item in context menu;
"Main menu" and "Context menu" are based on membership. I don't want to load them everytime my page loads, because that would consume resources database. So, I'm using ajax to load main menu only one time, and when an item is selected, I load the context menu for that item.
My problem is: Every form's post will erase my menu.
Question: Will I have to build my entire application using ajax? I don't wanna do that, because it is too much simpler do a post in the form then send all data to controller with ajax.
Until now, I have 2 options:
Load my menus with ajax and the page body with IFRAME, so the post's will not render again my menus.
Do everything using ajax;
Is there any alternative to load my menus with ajax and be able to use form's post?
Sorry if I wasn't clear enough.
The sentence that gave me a pause is this "I don't want to load them everytime my page loads, because that would consume resources database."
You see, I've build quite a lot of apps, that display menus and sub-menus based on user roles (what you called membership). This has never been an issue from the resources or database perspective.
You can access all the membership information that you need once, when your used is being logged in. In the simplest case user's identity will be stored in the context along with the roles they have (HttpContext.User), so you do not to need a database lookup at all to get this information on every request. Note that with this scenario no ajax is required either.
If for whatever reason you can't store your membership information in the context like this, you still can store in in session (if in-memory) or in encrypted Cookies.
Now, I understand, that I don't all the details of your scenario, and that may be in your scenario what you are trying to do is warranted, however I suggest you think it through again, as under normal circumstances what you indicate is a problem (database resource) should not be a problem at all.
The bottom line is: if you alter your application that it stores the membership information when user logs on you won't have your problem to start with.
You don’t have to build all of your application using Ajax. But in this scenario Ajax may be the best way forward.
Following is my suggestion
Create your data entry for inside a dev
Have each input controller marked with a class (say ‘dataEntry’)
Create a javascript function to iterate the dev and build a list of all elements that has class dataEntry
Build a json object using the list. Use the name of each element as property name and value as the property value
Use jquery ajax to post this to the controller action
[optional] you can use .done and .fail methods to take action on success or failures of the call
I know this may look intimidating, but if you have many data entry forms, you can re-use this code.
So a user fills out a form then decides to click on a unrelated link that happens to be on the page say to a disclaimer page. Then using internal site navigation (not the browser back button) comes back to the form he was on. The link back is an ActionLink.
What is the best way to keep his data on the form. I figure I'll have to serialize the data and save it. I can do a ajax call before going to the other page. I'm looking for the sexy solution. Something that will handle it on a global scale.
Is this even a standard practice?
HTTP is Stateless. You are trying to bring some Stateful nature it !
If you really want to keep the data, You can keep in the Session variable and access it there. You need to override the click event and (in javascript) send the form data to an action via jQuery ajax post where you store it into Session. You can access it later when you come back to this page.
Do you really want to do that ? I think 80 % people knows that once they click on another link, the data will go away. You could probably show some alert message to ask "Are you sure to leave this page" like stackoverflow does.
