Question

Return a JavaScript's confirmbox response to a ruby program.

Answer 1

A:

Sure, it´s easy. Just send an XHR back to the server. If your are using jQuery you could do something like this:

$.getJSON('/path/to/check', {client_data: stuff}, function(response) {
     //e.g. server returns
     if (response.ask && window.confirm("Sure?") || !response.ask) { 
         sendMyStuffToServer();
     }
})

An XHR request (aka AJAX) is basically the same as a normal one except that it's performed in background (which looks like what you are looking for).

It is very difficult to call JS form from Ruby (not sure what you mean here). For jQuery doc look here: http://api.jquery.com/jQuery.get/

glebm 2010-10-23 06:54:46

but is it possible to call JS from ruby or not??

AMIT 2010-10-23 07:00:18

What is exactly the problem you are trying to solve?

AMIT 2010-10-23 07:09:54

In my given code i would like to call javascript instead of messagebox

AMIT 2010-10-23 07:12:09

But surely that message box pops up as a result of some action from the user? Or you want to show it right after the page loads?

glebm 2010-10-23 07:12:23

OK, I looked at your code (for a bit, cause it's scary). You can ask the server with AJAX, *get the response*, *and then display the box if necessary*

glebm 2010-10-23 07:14:46

as soon as this condition is true i would like to call js is it possible if $L=(name.eql?(k[i]) == true)after that condition i would like to see that confirm box and thats box respone should be get in my ruby code is it possible glebm??

AMIT 2010-10-23 07:21:40

The idea is to make two separate actions. One would check your condition and return the result to the client (this is the action you'd call asynchronously). And then you can have the second action which javascript would call if the user clicked OK in the confirm box.

glebm 2010-10-23 07:27:15

any way Thanks glebm for your kind help i will try what you said and let you know its is working or not??

AMIT 2010-10-23 07:27:55

then where i call my

AMIT 2010-10-23 07:31:51

post = DataFile.save(params[:upload])

AMIT 2010-10-23 07:32:06

For the first action you can subscribe to `change` event on the file upload input. For the second action is the actual upload in your case.

glebm 2010-10-23 07:40:30

could you please explain how i did n't get you or by some example
