Jquery Drag and Drop Issues

I am having a problem with bringing Jquery over to iPad. I made a drag and drop puzzle using Jquery, and on my computer it works fine. When I try to move that over to the iPad, the drag and drop functions cease to work. I have tried many a third party fix for this problem with no avail. Does anyone know how to solve this problem on iOS5? Or is there a better way to code it in HTML5 that works or a Jquery solution I do not know of? Any tutorials on the issue would be appreciated as well. Thanks.

Gathering segmented data via jQuery with FOR loops

How to extract relative URL from argument values from request string?

I have a request url / string var like http://ip_or_url:4773/image_renderer.service?action=resize&from_format=png&from_url=http://ip_or_url:4773/my_file.user.file&to_format=jpg&w=1920&h=1200 It looks terribly scary. I wonder how to extract from_url=http://195.19.243.13:4773/my_file.user.file argument pair from it and then extract relative file url from that pair value my_file.user.file ?

get the true type prototype vs constructor?

I wanted to see the real type of [] . I always thought that i can use the apply method or the constructor . so i tried : [].constructor ->(showed me) function Array() { [native code] } and [].constructor.constructor ->(showed me) function Function() { [native code] } and Object.prototype.toString.apply([]) ->(showed me) "[object Array]" questions 1) Whom to believe ? 2)why line 2 is different ?

The best way to write Javascript / jQuery

I'm not new to web dev but I was just wondering if you guys have some advice for me to improve: Always when I write js or jQuery I write all the code like this in the <head> on my page: <script> $(document).ready(function() { //All my functions and animations goes here… }); </script> Now, when I look around the web I see that most people have their functions and animations in a separate ".js"-file. And they often create classes aswell. How does that work? What is the advantage of creating classes and have your functions in a separate file? Thanks, VG
