similar to: application/json request defaults?

Do I need something like this: eval(''('' + this.header(''X-JSON'') + '')'') (taken from Cody Swann, http://ajaxian.com/archives/prototype-extension-dynamic-script-pattern-support ). I''m guessing my problem is simpler, and I''m leaving something small out related to the header though. Thanks for any help -Mark 1. evalJSON:

I''ve the following situation (which actually works in Rails 2.3.8 and this is a result of the migration of our app to rails3): I have a partial which is rendered a few times (imagine tr''s in a table).

Hello Friends, What is the best way to send json from your controller, and await for a response? Ajax? Ruby''s net/http? The JSON server that I am sending the request to only accept POST methods, and sends a POST back. If I use Ajax, is it possible to get the POST response? Is there a scriptaculous or YUI function that handles this well? Thank you for your help - Jin

I''m using jrails and I found when I use the authenticity_token in certain javascript calls, that the url works differently in that the paramters in the :with clause get dropped if they are in a json type syntax. Below is an example of a remote_function() call from JS that used to work fine without authenticity. When I enabled authenticity it adds the authenticity token automatically, but

I am trying to send a POST request ( ''remove_tag_named'' )and getting a simple OK back on success ; it doesn''t work.. the post is correctly sent , but after then it''s looping on sending a GET request to the same url, with the error 301 Moved Permanently I should not be far fro the solution, but I am stuck : In my routes.rb *namespace

Hi everyone. I love JSON and using Prototype has help me reduce the code to handle AJAX responses. But one thing keeps me confused and sometimes even frustrated. I don''t really understand what is going on with the headers, so if someone could take some time to explain what is going on, I (and probably a lot more people) would be very thankful. The thing is this. On my local server (Mac OS

Hello all, I''m trying to send some json data from the browser to the server using prototype without success. On the server side ActiveSupport::JSON.decode isn''t decoding the data. Here is the code: Javacript: <a href="#" onclick=''send();return false;''>click</a> <script> function send() { var send_data_url =

Hi, I am using JQuery in my rails app. I''ve taken the approach outlined in Ryan Bates''s Railscast on jquery to do the following: jQuery.ajaxSetup({ ''beforeSend'' : function(xhr) {xhr.setRequestHeader("Accept", "text/javascript")} }); to set my ajax call request Headers to text/javascript so that my respond to block for javascript is

Hi, I have a long list (~50) of items which should each be clickable and will send an Ajax request to the server. Now, each item will be calling the same action, just with a different id. Ideally this looks like a clear case of putting the Ajax javascript in application.js. It''s in one place, just call a single function onclick and pass through the id. However there are 2 issues: 1. I

Hello list! I am taking my first steps with AJAX and decided to give prototype a try. - I add a reference to the script to my page - Then somewhere near the bottom of the page I fire up: new Ajax.Request(''ws_adrestype.php'', { method:''get'', requestHeaders: {Accept: ''application/json''}, onSuccess:

Hey, this is great to see this in trunk. It answers some questions I''ve been having about what is the best way to use JSON on the client side; it seems like the :callback approach is becoming the standard. A related question -- Prototype has this support for an "X-JSON" header that allows pure JSON to be sent in a response header and it gets evalled and passed to ajax

I''m not the best when it comes to javascript so this is probably a simple mistake. I''m using the following code to read an external json file and print out its values. The problem is when I try to write the value to the browser it causes the browser to load like it hasn''t finished the javascript code. Its writing the value to the screen so I think its hanging after that

Hello everyone, Just a note, I have to pass my JSON in the response body. I''m aware of the X-JSON header, but am passing too much data to use it. No problem and I have code that has it working well. While I''m getting my JSON data back and can do whatever I''d like with it in "setMakeVars", I''d like to set it to a global var "gljson" below,

My Java servlets can generate both JavaScript objects, like JSON, and XML. I can generate both pretty easily. What''s best practice for AJAX responses? Return scripts to be evaled by the Ajax control, or return XML documents and iterate them using XML DOM? Thanks. -- Alan Gutierrez - alan@engrm.com - http://engrm.com/blogometer/index.html -

I''m using Ajax.Updater to update a select element, and have just discovered that IE doesn''t like having its innerHTML set. I figure instead of a bunch of option tags I can return JSON and parse it to add the options, but I''m not quite sure of the best way to do this.... or any way to do it really :) Could someone point this out to me? Or am I using a totally antiquated
