Linking to javascript in a view subdirectory? - javascript

I have a view folder called 'HelloWorld', inside it I have another folder called 'table' with stuff inside it, I have something located here: table/media/js/jquery.js under the helloworld directory, I've set it to 'copy always' and its build action i s'Content'.
In the index of the view control I do this:
<script type="text/javascript" language="javascript" src="table/media/js/jquery.js")></script>
But for some reason it can't find it, if I try to manually go to it via the URL (i.e. http://localhost:XXXX/HelloWorld/table/media/js/jquery.js) the server still can't find it.
Any ideas how I'm supposed to make this work?

The View folder is not browsable for security reasons, then you cannot serve files like your javascript file.
See the web.config inside the View folder, the handler BlockViewHandler does this,
create a similar structure within the content folder if you need to organize files.

Assuming you have created the following folder: ~/HelloWorld/table/media/js/jquery.js where ~ is the root of your web site I would recommend you using url helkpers in order to generate proper url:
<script type="text/javascript" src="#Url.Content("~/HelloWorld/table/media/js/jquery.js")")></script>
On the other hand the Views folder is a special folder in which you should put only your MVC views and not static files such as css and javascript that are intended to be served directly on the client.

JavaScript path doesn't load on Live Server extension (VS Code)

HTML and CSS files are working perfectly on my live server. But every time I lead to a .js script it will not be shown on my live server. If I try to load the .js file directly through the URL it shows "Cannot GET /line.js". I already tried out everything I've found on the internet but it's still not working. Here are the points I checked/did:
Installed Code Runner
Installed Node.js = node.js system path done
Settings = Live Server Config = specified browser
"liveServer.settings.CustomBrowser": "chrome" on JSON settings
.js file is in a separate folder and accessed via <script src="line.js"></script> on index.html
Chrome is set as default browser on my system
Thanks for your inputs.
If the js file is in a separate folder, you need to provide the exact route to the folder in the script tag, since in the current form it is trying to find the js file in the root directory. The script tag should look like this:
<script src="FOLDER_NAME/line.js"></script>
It's possible that your javascript file is being loaded before the HTML page is rendered. You can try adding "defer" to your script tag like this:
<script src="demo_defer.js" defer></script>

Load a directory in a js with flask

I would like to declare in a script, a directory.
$images_dir = '{{url_for('.../pictures')}}';
My flask application directory looks like:
Root
-wep.py
-templates
-gallery.html
-static
-pictures
The picture are located inside the pictures folder, and the html page that contains the script is gallery.html which located in the templates folder.
The purpose of that script is to list all the images that are located in the pictures folder and present them as a gallery view when the gallery.html page is loaded.
The script works fine if I run it in a normal apache webserver though.
When I run the web.py, the debuger gives me the error:
BuildError: ('../pictures', {}, None)
So I think the problem is to declare the directory in flask.
UPDATE:
Im using this guy's script : http://davidwalsh.name/generate-photo-gallery
As you can see in the source code:
/** settings **/
$images_dir = 'preload-images/';
$thumbs_dir = 'preload-images-thumbs/';
Im trying to adjust those line to work with flask.
I think you're misunderstanding the purpose of url_for. url_for is for generating a link to one of your application's HTTP endpoints/view functions. You don't need any flask-specific method to get a list of files. You might find glob or os.listdir() helpful for this purpose. Then you can pass a list of the relevant paths to your template for rendering.

How do I link JS external files outside of my PHP project root directory?

On my site I have my resources folder outside of the root, for example:
/var/www/html/ is the root directory
/var/www/resources/
I currently have a config file that sets the location of the library so I can include it with php like so:
defined("LIBRARY_PATH")
or
define("LIBRARY_PATH", realpath(dirname(__FILE__) . '/library'));
which works perfectly when I use:
<?php include_once(LIBRARY_PATH . "/file.php"); ?>
but it doesn't work when trying to add Javascript files:
e.g.
<script src="../resources/library/js/test.js"></script>
links to 'www.website.com/resources/library/js/common.js'
or
<script src="<?php echo LIBRARY_PATH; ?>/js/test.js"></script>
links to 'www.website.com/var/www/resources/library/js/test.js'
neither of which work.
Any suggestions on how I can do this without having the js files in or above the root?
Your JavaScript files have to be accessible to the browser because they are executed by the browser and not by the server.
This requires that they have a URL.
Putting the files under the webroot is the standard way to give a static file a URL.
Alternatively, you could write a program (e.g. in PHP) that will read the file and then output it's content to the browser. This is more complicated and makes dealing with cache control headers more fiddly and is not recommended.
Assuming you understand what you're doing and security implications of that!..
You create the linkjs.php script that takes the relative path to the script (from some root dir, perhaps /var/www/resource/js) as a parameter, like:
<script src="/linkjs.php?p=test.js">
In your PHP script you resolve the full file path, check that it's indeed a file under the root dir (to protect against ../ in the parameter), that it's readable by you PHP user, read the content and output it into the response. Don't forget to set content type to text/javascript of course.
Ideally, you should also provide proper caching headers based on the source file modification time, but that is a topic in itself. See the guidelines in other SO questions about proper caching headers for dynamic content.
The upside is that you can do on-the-fly script minification/combining/wrapping/substitutions if you like/need.

Add a Javascript File to BigCommerce Template

I am attempting to add a javascript file to a BigCommerce template that will enable a function needed. I am not familiar with BigCommerce but was contracted to add this functionality.
How do I add a javascript file to a BigCommerce template?
I tried create a custom folder like so:
/template/_custom/my-javascript-file.js
but when I insert that file path into the template it throws a 404 error IE:
<script type="text/javascript" src="/template/_custom/my-javascript-file.js"></script>
How do I add an external javascript file to a BigCommerce Template?
First you need to upload your JavaScript file via WebDav. I would add it to /templates/js. If this folder doesn't exist, create it.
The file path would be:
<script type="text/javascript " src="/templates/__custom/is/my-javascript-file.is"></script>
Note that __custom does not actually exist in the folder structure.
Upload your javascript to js folder
Use webdav bro and copy the HTTP URL like this one --> http://store-d17df.mybigcommerce.com/js/jquery.fitvids.js
or the big commerce way--> < script src="%%GLOBAL_TPL_PATH%%/js/common.js">

PHP code-igniter

I'm having troubles calling my external js files from my views php pages. The js files are saved in the "resources" folder in the root folder i.e "root/resources/scripts/myfile.js" just like the "root/application" and the "root/system" folder.
so in one of my php files in the views folder i am using this code:
<script type="text/javascript"
src="<?php echo base_url();?>resources/scripts/welcome.js">
and this php file is located in "root/application/views/welcome.php"
and still my page cannot link with the java script so i am stuck big time.
regards
k..
Try this:
<script src="<?= base_url('resources/scripts/myfile.js')?>"></script>
Looking at your question and the comments below your question, it seems you are using "resource" in one example and "resources" in another example.
Once fixed, view the source of the page (I use FireFox, as it makes the links clickable), search for "welcome.js". Once found, click on the link for that file. If you see javascript, it means the file is found, alternatively you will see a 404 error.
First of all check if the resource folder is available,
The java script file is available and the file naming is in the same small or capital case, and server has public permission of the file and folder.
by the way your code has missing end tag
</script>
