I've seen a couple questions around here like How to debug RESTful services , which mentions:

I know how to deploy an applet using applet , object , embed tags and JavaScript , but I'm after the best approach (in terms of end user experience).

After a user uploads a file we have to do some additional processing with the images such as resizing and upload to S3. This can take up to 10 extra seconds. Obviously we do this in a background. However, we want to show the user the result page immediately and simply show spinners in place until the images arrive in their permanent home on s3.

I need to check if a css rule exists because I want to issue some warnings if a css file is not included.

I want to provide my visitors the ability to see images in high quality, is there any way I can detect the window size (or better yet, the viewport size - see green area ) of the browser with Javascript? Source: Tips4all

What is the best cross-browser way to detect the scrollTop of the browser window? I prefer not to use any pre-built code libraries because this is a very simple script, and I don't need all of that deadweight. Source: Tips4all

(By the way, a quick experiment indicates that the answer is "yes", but it might be "it doesn't work in every browser".) I am using a validator plugin that binds something to the submit event of a form. But I want to perform additional validation. It would seem that I can simply bind my additional validation to the submit event. HOWEVER, I worry that that might not work on every browser. Should I expect this to work or will I need to write more complex code?

I have what is a simple script to retrieve a simple message (string) from server and it appears there is no response from server, so I am wondering if JQuery is even firing off a request at all? The server side script (PHP) is so simple, basically it is just a plain echo. One moment the script is working in FF and the next moment it ain't, as for the other mainstream browsers, you can forget about it! Here is the JQuery script below, do you see anything I'm missing (considering I am new to JQuery / AJAX / Still learning)? Thanks. $(document).ready( function() { $( '.enlarge' ).click(function( e ) { e.preventDefault(); var img = $( this ).children( 'img' ).attr( 'alt' ); var url = '/pages/message/' + img + '/'; $.ajax({ url: url, data: '', cache: false, dataType: 'text...

I'm working on a site where I have input buttons (styled using CSS) that are a part of a form. For example, see below for sample code <input type="submit" name="buttonSave" value="save" id="buttonsavejs" class="button_image button_style"/> I've just found an issue where if a user clicks on the button, it moves a few pixels below and then expected action takes place intermittently . But intermittent , I mean that sometimes it works (redirects the user to the next page) and sometimes nothing happens. The developer who worked on this previously hasn't documented his code much, so I'm trying to work from scratch here (so excuse the lack of details). Anyway, after testing the code, it appears that the issue lies with how newer browsers are rendering the css and javascript. Here's a snippet of the javascript behind the button's functionality: $("#buttonsavejs").click(function(){ $(...

As Html code resides until new url request's response doesn't come .Then Browser calls BeforeUnload and Unload function. This means anywhere in the browser, the url is residing which has been hit for unloading the current one. So is there any way we can get that (new) URL in the Unload function? Actually My scenario is that I want pop up to be opened for providing the other options when user has just hit another URL which doesn't resemble to our domain , showing that he want to go out from our site.
