I'm writing an AJAX app, but as the user moves through the app, I'd like the URL in the address bar to update despite the lack of page reloads. Basically, I'd like for them to be able to bookmark at any point and thereby return to the current state. How are people handling maintaining RESTfulness in AJAX apps? Thanks in advance....
I've got an web application that I'm trying to optimise. Some of the controls are hidden in dialog-style DIVs, so I'd like to have them load in via AJAX only when the user wants to see them. This is fine for controls that are mostly Literal-based (various menus and widgets), but when I have what I call "dirty" controls - ones that writ...
I have a problem with maintaining state in an ASP.NET AJAX page. Short version: I need some way to update the page ViewState after an async callback has been made, to reflect any state changes the server made during the async call. This seems to be a common problem, but I will describe my scenario to help explain: I have a grid-like c...
Jeff mentioned the concept of 'Progressive Enhancement' when talking about using JQuery to write stackoverflow. After a quick Google, I found a couple of high-level discussions about it. Can anyone recommend a good place to start as a programmer. Specifically, I have been writing web apps in PHP and would like to use YUI to improve th...
I have a simple page with my ScriptManager and my UpdatePanel, and my ContentTemplate has one ListBox and one Label. I am just trying to catch its OnSelectionChanged so I can update the text in the Label. No matter what settings I try to tweak, I always get a full-page postback. Is this really not going to work, or am I just screwing thi...

The Setting: The program in question tries to post form data via an AJAX call to a target procedure contained in the same package as the caller. This is done for a site that uses a secure connection (https). The technology used here is PLSQL and the DOJO JavaScript library. The development tool is basically a text editor. Code Snippet: ...

Hi everoyone, Yesterday, a friend of mine asked me to suggest to him an interesting Ajax based project to do in his spare. I first thought that it'll be an easy task but no idea came out! So is there any interesting idea out there? The difficulty level wouldn't be a problem as he is willing to learn Ajax and for me, nothing better tha...

I have an Ajax.Net enabled ASP.Net 2.0 web site. Hosting for both the site and the database are out of my control as is the database's schema.

I've got a div that uses overflow:auto to keep the contents inside the div as it is resized and dragged around the page. I'm using some ajax to retrieve lines of text from the server, then append them to the end of the div, so the content is growing downwards. Every time this happens, I'd like to use JS to scroll the div to the bottom so...
Hello, I wonder if someone knows if there is a pre-made solution for this: I have a List on an ASP.net Website, and I want that the User is able to re-sort the list through Drag and Drop. Additionally, I would love to have a second list to which the user can drag items from the first list onto. So far, I found two solutions: The Reor...
What's the best practice for making sure that certain ajax calls to certain pages are only accepted from authenticated users? For example: Let's say that I have a main page called blog.php (I know, creativity abounds). Let's also say that there is a page called delete.php which looks for the parameter post_id and then deletes some ent...
I love the ease that the ASP.NET Ajax control Toolkit provides to ASP.NET developers. However, I've not found it to be a scalable solution at all. I have a page with 2 date input fields. By putting a TextBox and an CalendarExtendar control attached to it for each date field, I get several (11, in fact) external Javascript calls to /Scrip...
If you're building an AJA~Xy app, are there any downsides to using JSONP requests/responses even if you're not planning on any cross-domain requests? The only thing I can think of is that there are a couple extra bytes for the callback wrapper... Edit: I found this which also suggests security and error handling as potential problems....
Of course I am aware of Ajax, but the problem with Ajax is that the browser should poll the server frequently to find whether there is new data. This increases server load. Is there any better method (even using Ajax) other than polling the server frequently? ...

I have a script that retrieves objects from a remote server through an Ajax call. The server returns objects in JSON notation. However, in Adobe AIR, there is a restriction on using eval() for security reasons. So I'm able to get replies from the remote server, but can't turn them back into Javascript objects. Is there any workaround fo...
For an application I'm building in my spare time I am looking for (arguably) the correct way to return data from an XmlHttpRequest. Options I see are: Plain HTML. Let the request format the data and return it in a usable format. Advantage: easy to consume by the calling page. Disadvantage: Very rigid, stuck with a fixed layout. XML. L...
