jquery as a local resource

When I use the following header
<script src="http://code.jquery.com/jquery-1.8.3.js"></script>
<script src="http://code.jquery.com/ui/1.9.2/jquery-ui.js"></script>
There is no error in my HTML file. But I am facing a problem. Every time I am loading this page , there is the need for internet connectivity.
I have developed an webpage through which some instruments would be controlled through node.js acting as a server. This would be accesible in the intranet (between local computers in LAN) only.
Is there any method to use jquery as a local resource, i.e. If i download and save these files and use it from the local hard disk.
I saved both the files jquery-1.8.3.js and jquery-ui.js in the same folder as the html and used it with <script src="/jquery-ui.js"></script> it is giving resource not found 404 error.

If the .js file is in the same folder as the .html, then you should be able to include it with
<script src="jquery-1.8.3.js"></script>

Download the jquery and put it in your scripts folder and use like this
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script>window.jQuery || document.write('<script src="scripts/jquery-1.8.3.min.js"><\/script>')</script>
This will first check for the CDN if exist it will load from CDN other wise it will take local one

Ajax javascript n jquery src reference issue

I am new to Jquery and AJAX. I am trying to upload the file using AJAX call. When I set the script reference as from website, its working fine, but when I download it and set reference as local folder, its not working. What is wrong with my code?
When I use :
<script src="http://malsup.github.com/jquery.form.js"></script>
its working fine,
but when I use
<script type="text/javascript" src="http://localhost:8080/Upload/js/jquery.js"></script>
or
<script type="text/javascript" src="js/jquery.js">
its not working......

Add jquery.form.js library in your website folder under js folder, and
Change
<script type="text/javascript" src="js/jquery.js">
To
<script type="text/javascript" src="js/jquery.form.js">

This version points to a file on that web site:
<script src="http://malsup.github.com/jquery.form.js"></script>
This version points to a file on your LOCAL server (machine) via port 8080 (usually NOT a great idea)
<script type="text/javascript" src="http://localhost:8080/Upload/js/jquery.js"></script>
This verison points to a js folder relative to the page it is linked on
<script type="text/javascript" src="js/jquery.js">
In order to use a file locally (like the last two), you will need to download that file, and save it to your web server (or local server) in a folder. In the second example, this would mean saving it to the Upload\js folder at the root of your local servers site (that machine).
In the third example, you would need to find the page it is linked in, create (if not present) a js folder under that folder and save the js file at that location.
Note that it is always a good idea to use the original name form or something similar rather than jQuery.js - as that is often confused with the jQuery library itself.
An examples might be save it as:
jquery.form.js
malsup.jquery.form.js
malsup.version1.jquery.form.js
or some such named instance.
NOTE One way of making this as generic as might be would be to use
<script type="text/javascript" src="/Upload/js/jquery.js"></script>
This points to a folder called Upload with a sub folder js (Upload\js)which is based at the root of your web site. For instance if your site is based at your windows e: drive in a wwwroot folder it might be:
E:\wwwroot\Upload\js\malsup.jquery.form.js

javascript object expexted

I am unable to call a javascript function as it says "Object Expected". I am using asp.net and this is being used on a standard aspx page with some usercontrols. One of the user controls called CookieControl calls a javascript method setandCheckCookie() on document.ready.i.e
$(document).ready(function() {
setandCheckCookie();
)};
In the head section on my aspx page I have reference the javascript file before I add the control:
<script src="CookiesControl/js/Cookie.js" type="text/javascript"></script>
<uc2:Cookie ID="Cookie1" runat="server" />
I've event tried adding the script reference on the user control itself but when I go to my aspx page I get the object expected error.
I don't believe its the control or the js file as both these are used elsewhere in the website and they work fine but something I'm doing is stopping the js file from being reference because in firebug and IE debugger I can't see the referenced js file.
Perhaps the path is incorrect but I have dragged the script from the solution explorer and visual studio isn't complaining about the path either.
So my question is: what could potentially stop my javascript file from being referenced.

Visual Studio complaining or not about a path is not always saying what you'll get in the browser. To check if the script is referenced ok, try to get the script file in the browser. For example, if you page is at http://yoursite/yourpage.aspx and your script reference in the html code (by View Source, not what you see in Visual Studio) is folder/scriptFile.js, put this address http://yoursite/folder/scriptFile.js and see if you get the file. If not, then it is not referenced ok.
To solve issues like that, put the full path after yoursite, like:
<script src="/ScriptVirtualFolder/CookiesControl/js/Cookie.js" type="text/javascript"></script>
where ScriptVirtualFolder is in your site root folder, and it is a virtual folder, means it is accessible by the browser in this path.
Also, you can use asp.net to resolve your path by using the ~ sign and runat='server'. For example:
<script src="~/ScriptServerFolder/CookiesControl/js/Cookie.js" type="text/javascript" runat="server"></script>

Edit external JavaScript file after breakpoint is hit

In the VS2010 IDE when a breakpoint (or an error) is hit, it opens a read-only [dynamic] version of the external JavaScript file I referenced. My workflow would be vastly improved if I could immediately edit this file, and refresh the browser. That is as opposed to digging up the original JS file opening it, finding the correct line and editing there.
I only know that this is possible because I was able to do this on my old work computer configuration, but for the life of me I can't duplicate it at home.
Has anyone made this work? Perhaps an extension? or maybe it has to with the way the files are referenced, or my basehref tag, or url rewriting.

This happens when the base href specifies a domain other than localhost. My issue was that to enable a local environment for Facebook JS, I need my domain in the url. So I set up my host file to remap localhost.mydomain.com to localhost.
When the Visual Studio IDE encounters a file reference which is something other than localhost, it does not attempt to grab the local file since it assumes (correctly in most cases) that it is being served from another site. In these cases it loads a file as [dynamic] and readonly.
Here is the test case:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<base href="http://localhost.mydomain.com/virtual-directory/" />
<script type="text/javascript" src="test.js"></script>
</head>
<body>
</html>
Any breakpoint within test.js will result in opening a readonly dynamic file.

how are you referencing your files? whenever a script block is written inside the html or is dynamically inserted the debugger will open the instance of the page where the code stops. If you reference the script using tags vs should open the original script file (at least that's what it does on my machine). could you upload an example of your current structure?

web application root operator and script tags

Is there any way to use ASP.NET's 'web application root' operator ~ in a script tag? If not, is there any way to mimic such behavior?
My application uses nested master pages for different sub directories; A content page uses its directory-specific master page, which uses the root master page. I'd like to be able to include my <script> tags in the root master page, so I'm not repeating code all over the place, but since I don't necessarily know the depth of the path for any given content page, I can't reliably provide paths to the scripts folder.
I considered using paths in the form /scripts/jquery.js, but since the Visual Studio development server starts the application in a subdirectory of the server root, this will not translate well to the live server. To illustrate:
<!-- dev server path -->
<script type="text/javascript" src="/my_project/scripts/jquery.js"></script>
<!-- live server path -->
<script type="text/javascript" src="/scripts/jquery.js"></script>
You can, of course see the issue. Since I am not the only developer on the project, I have very little control over what happens in the "go live" process; otherwise, it could just be a matter of removing /my_project in the "go live" process.

There are some possible cases on that.
1) For large project use the local iis5.1 or other local iis, and not the VS web that runs.
2) You can avoid the first spash and use relative paths... eg:
<script type="text/javascript" src="scripts/jquery.js"></script>
<script type="text/javascript" src="../scripts/jquery.js"></script>
so you do not force him to start from beggining.
3) You can place a literal control there and just render the script tag on Page_Load with the correct path every time
4) and you can just render the src on page
<script type="text/javascript" src="<%=ResolveUrl("~/scripts/jquery.js")%>" ></script>
I am using the 1 and 3.
