I have a simple aspx page using jQuery globalize plugin that I created based on the Demo solution from this url: https://weblogs.asp.net/scottgu/jquery-globalization-plugin-from-microsoft.
I am using Visual Studio 2013 Pro version with .Net framework 4.5.1 and the project with this aspx page is a website project.
I always get a JavaScript error when this simple aspx page renders. A screenshot of this error is as below.
The markup of this simple aspx is also given below. No code-behind code is being used for this page.
Question : What could be causing this since similar code in Demo samples from Scott's blog works without any errors? All script files are correctly loading that I verified in Chrome's Source tab, so this is very confusing.

I finally found the problem. The minified file jQuery.glob.min.js that was in the Demos solution at https://weblogs.asp.net/scottgu/jquery-globalization-plugin-from-microsoft was not correct, but jQuery.glob.js from same location was correct since my aspx page worked with it.
So I just created a new minified file using jQuery.glob.js and then everything worked perfectly with my aspx page.
This was working on Friday, and now isn't. I've got this at the beginning of a UserControl:
<link type="text/css" href="/App_Themes/css/ui-lightness/jquery-ui-1.8.11.custom.css" rel="stylesheet" />
<script src="/Scripts/jquery-1.5.1.min.js" type="text/javascript"></script>
<script src="/Scripts/jquery-ui-1.8.11.custom.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
$("#MainContent_ucSearchControl_dpPickupStart").datepicker();
$("#MainContent_ucSearchControl_dpPickupEnd").datepicker();
});
</script>
And further down, this:
<td><asp:TextBox id="dpPickupStart" runat="server" style="width: 65px"/></td>
<td><asp:TextBox id="dpPickupEnd" runat="server" style="width: 65px"/></td>
Which results in (in the rendered page) input controls with:
name="ctl00$ctl00$MainContent$ucSearchControl$dpPickupStart" id="MainContent_ucSearchControl_dpPickupStart"
name="ctl00$ctl00$MainContent$ucSearchControl$dpPickupEnd" id="MainContent_ucSearchControl_dpPickupEnd"
And yet, every time the page loads, I get an Object Expected javascript error which points to the $(document).ready location.
What am I missing?
EDIT: Firebug is reporting that:
$ is not defined
[Break On This Error] $(document).ready(function () {
Being a user control you cannot guarantee that the relative path to your JS files will always be correct depending on the location of the parent page in the file system hierarchy.
Therefore change you JS script tags as follows to use the Control.ResolveUrl method which converts a URL into one that is usable on the requesting client.
<script src='<%=ResolveUrl("~/Scripts/jquery-1.5.1.min.js")%>' type="text/javascript"></script>
<script src='<%=ResolveUrl("~/Scripts/jquery-ui-1.8.11.custom.min.js")%>' type="text/javascript"></script>
Or reference from a CDN for added performace bonus of caching.
jQuery hosted on google
jQuery UI hosted on google
That error is caused due to Jquery not available. I think Swaff's solution should work(+1). Check if you have the Jquery-1.5.1.min.js file is available in Scripts folder of your solution. Or it could also be that your Scripts folder is renamed.
HTH.
I included mootools le this
<script language="javascript" src='<%# ResolveClientUrl("~/Scripts/mootools-core-1.3.1-full-compat.js")%>' type="text/javascript"/>
It compiles but when running it's blank page. If I remove page shows up again. How to fix this ?
You have double type and also your script tags aren't properly closed, try this:
<script type="text/javascript" src='<%# ResolveClientUrl("~/Scripts/mootools-core-1.3.1-full-compat.js")%>'></script>
Because i want to set a Extender (Calendar from the AJAX Controls toolkit) on a textbox,
I have to change the code from
<%= Html.TextBox("name") %>
to
<asp:TextBox ...>
But how can i bind the attribute "name" on the element?
Thank you
Have you tried using the jQuery DatePicker? It's much more friendly with MVC than the standard ASP controls and related extenders.
<%= Html.TextBox( "name" ) %>
<script type="text/javascript">
$(function() {
$('[name=name]').datepicker();
});
</script>
It's possible to use the asp.net Ajax Beta to create a client side Calendar.
See here:
http://www.asp.net/ajaxlibrary/HOW%20TO%20Use%20the%20Calendar%20Control.ashx
Strangely this version of the asp.net ajax library uses JQuery as well.
I would personally use the JQuery version... But the new asp.net ajax library is trying to evolve so that it works better with 'pure' html and asp.net mvc.
Ok,
I included the js from the google api, also the css.
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/jquery-ui.min.js"></script>
<link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/themes/overcast/jquery-ui.css" type="text/css" rel="Stylesheet" class="ui-theme" />
Then set the datepicker like this:
<script type="text/javascript">
$(document).ready(function() {
$("#startDate").datepicker();
});
</script>
I'm trying to add a script reference to jQuery in my master page so that it will work for any page. It currently looks like this
<script type="text/javascript" src="jquery.js"></script>
The problem is that the path is always relative to the executing aspx page so this will only work if the "jquery.js" file is located in the same folder. To make it work I have to change the line to:
<script type="text/javascript" src="../../jquery.js"></script>
This is obviously less than ideal because it will only work for pages that are two levels deep from the root folder. If I try the following, IIS throws an error about an unexpected character.
<script runat="server" type="text/javascript" src="~/jquery.js"></script>
Any ideas?
EDIT: I forgot to mention as well that the script MUST be in the head tag
The current top answer throws a "ASP.NET Ajax client-side framework failed to load." error when I add it to my master page. Its thrown from javascript and not the .Net compiler. If I move the ScriptManager to the head section where it should be I get a compile error about the ScriptManager needing to be inside a form tag.
The third answer throws a "Illegal characters in path." exception from the compiler
EDIT 2: When I add that line to my head tag I get this error from IIS.
The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>)
SOLVED: I took the edited response from the answer below and put it inside an asp:ContentPlaceHolder element
You could use a ScriptManager:
<asp:ScriptManager ID="ScriptManager1" runat="server">
<Scripts>
<asp:ScriptReference Path="~/jquery.js" />
</Scripts>
</asp:ScriptManager>
EDIT: If you absolutely need this in your <head> section, you could do something like:
<head>
<script type="text/javascript"
src="<%= Page.ResolveClientUrl("~/jquery.js") %>"></script>
</head>
EDIT 2: According to the comments, if you are observing that
The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>)
you may need to change the above to use the data-binding syntax:
<head>
<script type="text/javascript"
src="<%# Page.ResolveClientUrl("~/jquery.js") %>"></script>
</head>
Try <%# instead of <%= in Master page under head section
<script type="text/javascript"
src="<%# ResolveUrl("~/YourScriptFolder/YourJQueryOrJavascript.js") %>">
</script>
Then in Code Behind of Master page under Page_Load Event
Page.Header.DataBind();
Now you are good to go with either jQuery and JavaScript as well as CSS just you need to change your path in ResolveUrl which file you want to handle CSS, JavaScript, jQuery.
If you're not going to us asp:ScriptManager or absolute paths then you can do it like this:
<script runat="server" type="text/javascript"
src='<%= Page.ResolveUrl("~/jquery.js") %>'></script>
I do not know whether you guys found the solution to your problem or not. I was facing the same problem and going nuts to figure out why do I get "jQuery is undefined" error on the plugins i use. I tried all the solutions i get from the internet but no luck at all.
But, suddenly something splash on my mind that may be the script files should be in order. So, I moved the jquery referece to first position and everything start working like charm.
Remember guys, if you're using any plugins with jquery, make sure you use the folloing order of setting reference to those fiels.
reference to the jquery library
reference to the other subsequent plug-in libraries and so on...
e.g.:
"script src="js/jquery-1.3.2.min.js" type="text/javascript"...
"script src="js/jqDnR.min.js" type="text/javascript"...
"script src="js/jquery.jqpopup.min.js" type="text/javascript"...
"script src="js/jquery.bgiframe.min.js" type="text/javascript"...
Always make sure you must put the jquery reference to first and then the subsequent libraries.
Hope, this solves your problem especially when you use with MasterPages. Its very strange that it works no matter what order you use when you don't use MasterPages but when you do, then it somehow requres the proper order.
Good luck and happy coding,

Look at How to Run a Root “/”. This should fix all your issues regarding unresolved .js file paths. You basically reconfigure the VS Dev server to run your application as localhost:port/ as opposed to the regular localhost:port/application name/ making name resolution work the same way as it does on IIS.
For absolute path of the file for any page use it following:
<script type="text/javascript" src="<%= Page.ResolveClientUrl("~/jquery.js") %>"></script>
<script type="text/javascript" src="/full/path/to/jquery.js"></script>
If this script tag goes directly to the browser, then you unlikely can substitute your site's root there. At least not on the server. So you can:
Deploy site to the root of domain
name and use absolute paths
(simplest solution).
Insert this
link with server control.
Preprocess resulting HTML before
sending it to the client (with
HttpResponse.Filter).
You can also use <base> HTML tag:
<base href="http://www.domain.com"></base>
and then all the links in header section are relative to base address:
<script type="text/javascript" src="scripts/jquery.js"></script>
It's often useful when you have multiple publishing destinations, like local dev web server, demo server, etc. You just replace that base URL.
<body>
<script language="javascript" src='<%= this.ResolveClientUrl("~/full/path/to/jquery.js") %>' type="text/javascript"></script>
</body>
