HTML

You typically don't want any scripts in the <head /> apart from scripts like Modernizr that have feature detection. It's more of a best practice to move all scripts to the bottom of the page like so:

<html>
<head runat="server">
    <title></title>
    <link rel="stylesheet" href='<%= ResolveUrl("~/css/style.css") %>' />
    <asp:ContentPlaceHolder ID="Head" runat="server" />
</head>
<body>

    <!-- Scripts at bottom of page for faster loading. -->

    <script src='<%= ResolveUrl("~/js/jquery-1.7.1.min.js") %>'></script>
    <script src='<%= ResolveUrl("~/js/script.js") %>'></script>

</body>
</html>

SCRIPT.JS

Referencing the other script files in script.js will require the / to be appened to 'js/` like so:

$.include('/js/superfish.js');
$.include('/js/FF-cash.js');
$.include('/js/tms-0.4.x.js');
$.include('/js/uCarausel.js');
$.include('/js/jquery.easing.1.3.js');
$.include('/js/jquery.tools.min.js');
$.include('/js/jquery.jqtransform.js');
$.include('/js/jquery.quicksand.js');
$.include('/js/jquery.snippet.min.js');
$.include('/js/jquery-ui-1.8.17.custom.min.js');
$.include('/js/jquery.cycle.all.min.js');
$.include('/js/jquery.cookie.js');

if($('.tweet').length)
    $.include('/js/jquery.tweet.js');

if($('.lightbox-image').length)
    $.include('/js/jquery.prettyPhoto.js');

if($('#contact-form').length || $('#contact-form2').length)
    $.include('/js/forms.js');

if($('.kwicks').length)
    $.include('/js/kwicks-1.5.1.pack.js');

if($('#counter').length)
    $.include('/js/jquery.countdown.js');

if($('.fixedtip').length || $('.clicktip').length || $('.normaltip').length)
    $.include('/js/jquery.atooltip.pack.js');

// Slider
$('.main-slider')._TMS({

You can include a .js file either between the head tags , contentplaceholder tags or inside the body tags. This will in all cases be reflected in your other pages that include this masterpage. All you need to focus on is the way that the path is created.

The code below adds a jquery file to a masterpage in the head section of the masterpage.

<%@ Master Language="C#" AutoEventWireup="true" CodeFile="MasterPage.master.cs" Inherits="MasterPage" %>

<title></title>

<script src="jquery-2.1.1.min.js"></script>

<asp:ContentPlaceHolder id="head" runat="server">
</asp:ContentPlaceHolder>

<form id="form1" runat="server">
<div>
    <asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server">


    </asp:ContentPlaceHolder>
</div>
</form>
<script>

</script>

Relative vs Absolute URL's

By using ../ and ~/ before the url path , you are creating a relative URL. The paths of relative URL's is affected when you change the folder level of either the file that you are referring to or the file which contains the link.

../ symbol make one step out of the folder containing the link. make sure you have enough '../' to refer to the correct file.

~/ symbol creates a path that starts at the root of your project.

To create an absolute URL ,Just drag the file you intend to include in the page from solution explorer in Visual Studio to the page.

For more about the difference between absolute and relative URL's check Difference between Relative path and absolute path in javascript

Solution 3

Try replacing ~/ with ../. One of my projects was doing the same thing and that fixed it.

Also, make absolutely certain that even on the server (and not just in the project), the JS folder is directly below the root.

I am building an ASP.NET Webform application with C# in VS 2012, .NET framework 4.5

I have a MasterPage in root of application, JavaScript files are in folder named js.

Here is the problem: If page are in root folder then everything is working fine (css+js), if I put any pages in subfolder then css is worked but those JavaScripts are not working at all, obviously the reference path is wrong.

So the Css reference path is fine, but for the script no matter what I used they all are not worked (js/script.js or ~/js/script.js or /js/script.js or ../ ResolveUrl, ResolClientveUrl ... or all of method in this http://yobriefca.se/blog/2010/10/19/%3C-head-%3Eache-including-javascript-in-asp-dot-net-master-pages/ ) they all refer to root/SUB-FOLDER/js/script.js instead of root/js/script.js

in root: a single MasterPage, Default.aspx, test.aspx, js folder, css folder and Pages folder. Default and test pages are working file, but all pages in Pages folder is not display .js SO OBLIVIOUSLY the path is wrong whenever pages is not in root

In my master page:

<head runat="server">
<title></title>

<link rel="stylesheet" href="~/css/style.css" />

<%-- tried these and lot more but NOT workkkkkkkkkkk --%>

<%--<script src="~/js/jquery-1.7.1.min.js" ></script>
<script src="~/js/script.js" ></script>--%>

<%--<script src='<%=ResolveUrl("~/js/jquery-1.7.1.min.js") %>' ></script>
<script src='<%=ResolveUrl("~/js/script.js") %>' type="text/javascript"></script>--%>

<%--<script src='<%=ResolveClientUrl("~/js/jquery-1.7.1.min.js") %>' type="text/javascript"></script>
<script src='<%=ResolveClientUrl("~/js/script.js") %>' type="text/javascript"></script>--%>

<asp:ContentPlaceHolder ID="Head" runat="server">
</asp:ContentPlaceHolder>

the script.js is somthing like:

....
    $.include('js/superfish.js')
$.include('js/FF-cash.js')
$.include('js/tms-0.4.x.js')
$.include('js/uCarausel.js')
$.include('js/jquery.easing.1.3.js')
$.include('js/jquery.tools.min.js')
$.include('js/jquery.jqtransform.js')
$.include('js/jquery.quicksand.js')
$.include('js/jquery.snippet.min.js')
$.include('js/jquery-ui-1.8.17.custom.min.js')
$.include('js/jquery.cycle.all.min.js')
$.include('js/jquery.cookie.js')
$(function(){
    if($('.tweet').length)$.include('js/jquery.tweet.js');
    if($('.lightbox-image').length)$.include('js/jquery.prettyPhoto.js');
    if($('#contact-form').length||$('#contact-form2').length)$.include('js/forms.js');
    if($('.kwicks').length)$.include('js/kwicks-1.5.1.pack.js');
    if($('#counter').length)$.include('js/jquery.countdown.js');
    if($('.fixedtip').length||$('.clicktip').length||$('.normaltip').length)$.include('js/jquery.atooltip.pack.js')
// Slider
    $('.main-slider')._TMS({
.....

ok so I edit script.js file as you suggeted (basically removed /js), I still get Failed to load resource: the server responded with a status of 404 (Not Found) localhost:52403/Pages/js/jquery-1.7.1.min.js So obviously it is always point to SUBFOLDER then js/script.js rather than directly point to js/script.js Failed to load resource: the server responded with a status of 404 (Not Found) localhost:52403/Pages/js/script.js

Master page like you showed, <script> at bottom right above </body> tag, remember pages in root folder (same as masterpage) is worked fine

So, is the js folder on the same folder level as the MasterPage?

in root: a single MasterPage, Default.aspx, test.aspx, js folder, css folder and Pages folder. Default and test pages are working file, but all pages in Pages folder is not display .js SO OBLIVIOUSLY the path is wrong whenever pages is not in root
