[javascript] Failed to load resource: the server responded with a status of 404 (Not Found)

I can't solve my link problem. Could you help on to this to link CSS and JS File?

CSS:

<link  href="../Jquery/jquery.multiselect.css" rel="stylesheet"/>
<link  href="../Jquery/style.css" rel="stylesheet" />
<link  href="../Jquery/prettify.css" rel="stylesheet" />

JS:

<script  src="../Jquery/jquery.multiselect.js"></script>
<script  src="../Jquery/prettify.js"></script>

Error:

Failed to load resource: the server responded with a status of 404 (Not Found) http://localhost:8080/RetailSmart/jsp/Jquery/jquery.multiselect.css
Failed to load resource: the server responded with a status of 404 (Not Found) http://localhost:8080/RetailSmart/jsp/Jquery/style.css

Refer this link Directory structure.

I have added app.UseStaticFiles(); this code in my startup.cs than it is fixed

Note the failing URL:

Failed ... http://localhost:8080/RetailSmart/jsp/Jquery/jquery.multiselect.css

Now examine one of your links:

<link href="../Jquery/jquery.multiselect.css" rel="stylesheet"/>

The "../" is shorthand for "The containing directory", or "Up one directory". This is a relative URL. At a guess, you have a file in /jsp/<somefolder>/ which contains the <link /> and <style /> elements.

I recommend using an absolute URL:

<link href="/RetailSmart/Jquery/jquery.multiselect.css" rel="stylesheet"/>

The reason for using an absolute url is that I'm guessing the links are contained in some common file. If you attempt to correct your relative pathing by adding a second "../", you may break any files contained in /jsp.

If you have resource with woff extension and getting error then add following code in your web.config application will help to fix.

<system.webServer>
<staticContent>
   <mimeMap fileExtension=".woff" mimeType="application/x-font-woff" />
</staticContent>
</system.webServer>

For Resources like JavaScript or CSS not found then provide the path of adding link or script in following way

<link ref="@(Url.Content("path of css"))" rel="stylesheet">

<script src="@(Url.Content("path of js"))" type="text/javascript"></script>

Add this below code(<handler>) on your web.config within <system.webServer>:

<system.webServer>
<handlers>
  <remove name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" />
  <remove name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" />
  <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
  <add name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness32" responseBufferLimit="0" />
  <add name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness64" responseBufferLimit="0" />
  <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
</handlers>
</system.webServer>

I was having this exact issue and this was because I was returning images from a server into component that is 1 step down the path. This what I mean. See file arrangement

*projectfolder/phpfiles/component.php*

Now my images folder was located here projectfolder/images/

Now I fixed it by adding ../ so that it could skip 1 step backwards

Goodluck

Please note , you might need to disable adblocks if necessary. Drag and drop off script path in visual studio doesn't work if you are using HTML pages but it does work for mvc ,asp.netwebforms. I figured this after one hour

Please install App Script for Ionic 3 Solution npm i -D -E @ionic/app-scripts

Add this to your Configuration file. Then put all your resources(eg. img,css,js etc) into the src > main > webapp > resources directory.

public class Config extends WebMvcConfigurerAdapter{
   @Override
   public void addResourceHandlers(ResourceHandlerRegistry registry) {  
    registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
   }
}

After this, you can access your resources like this.

<link href="${pageContext.request.contextPath}/resources/assets/css/demo.css" rel="stylesheet" />

For me the error was the files under js folder not included in the project this solve my issue :

1- In the solution explorer toolbar click Show All Files.

2- open js folder and select all files under the folder

3- right click then select include In Project

4- Save and build your application then its working correct and load .css and .js files

If your URL is:

http://127.0.0.1:8080/binding/

Update the below property in the index.html

<base href="/binding/">

In short, you need to check the locations of the files.
