Play Framework 2.2-进行Ajax调用时处理Url参数

Question

I have a listing page to delete profiles, if the profile is deleted I need to redirect to the same page and display a message "Profile deleted".

If it was a regular form I'd use Play Framework's @helper.form and invoke the action in the controller. When that's the case:

In my action method I use Redirect(controller.action).flashing("message" -> "some message") and it works fine. I also use Ok(views.html.profile("some message",filledForm)) if I need to show the page with existing content, and it works fine.

However, since this is just a list I added a button and then perform an ajax call from javascript:

If it was successful then I redirect using: window.location.replace("/profile/prof_deleted"); I use the message (/prof_deleted) to show confirmation/error in profile template. However, if the user tries reloading the page, the confirmation/error will be displayed again since it is included in the url.

I need to pass the message but I think a session is not a good option in this case, flashing is not an option here and url parameter will always displayed.

It doesn't make sense, if you are using AJAX for sending request for deleting object why do you want to perform common page redirect after all ?

You have two better options for this scenario (I prefer second one)

1. Don't use AJAX, just common POST request with the same route as GET ie: /profiles then when sending POST it deletes object and shows message, otherwise shows list of profiles only.
2. Use AJAX properly: at success state just remove the item from HTML using JavaScript, display message box also with JavaScript but do NOT reload the whole page.
   • For deleting required item you just need to give them unique ID, ie: profile_123
   • There are some ready-to-use, nice libs for displaying info messages via JS, ie: noty
