I've been working on a game in javascript for my CS course. When I open the document by hitting run in Webstorm, it loads the game correctly, however when I just try opening the html file from Finder, the webpage opens but none of the png files I'm using for the sprites load. I opened Inspect Element in google chrome, and the javascript files loaded correctly but all the png files listed as canceled. This doesnt happen when the game is run from webstorm (when I run it from webstorm, all image files load properly).
When the game is opened directly from an html file (that's when I have the problem), chrome lists the path of the html document as the webaddress, although when opened from webstorm, it lists http://localhost:63342/CS%20Week%2010/CS105_Jessica.Davis_DogGame.html?_ijt=tmrr2fndgac82h07hlvt101gi4
How can I get around this issue so that when opening the html file from Finder it loads everything correctly? All image files are in the same directory as the html file.
Because of browsers security, loading files like this might not work from a url starting with file://
What webstorm is probably is making a local web server so that instead of saying file:// you could say http://. if any website was able to load images from file:// then any webpage you visit would have been able to search for any file on your computer and send it over the internet without your consent so browser often have these settings on. So you'd need a server. If you are working on your computer, you could make a local server just like webstorm and host your own files there. or host it on another service like github pages or codepen.
Now since all images are in the same directory, make sure that every time you call loadImage you use the images name and extension instead of saying /User/user/whatever_other_directory_you_have_it_under/image.png.
Once you did that you can make a local web server for the project. To make a local server, open Terminal (an application under utilities, you could spotlight search for it as well) and type cd, drag your project folder and drop it over terminal, and hit enter. Then type python -m SimpleHTTPServer and wait till it says something like Serving HTTP on 0.0.0.0 port 8000 .... Then taking the 0.0.0.0 and the 8000 you see in the example (yours may or may not be the same) go to your browser and type http://0.0.0.0:8000 (replacing the digits with whatever you got, not this link doesn't work until you do that)
Images should load alright. If you need to stop the server you can go back to terminal and hit control+C.
Note that when presenting your p5 sketch, no one else would be able to see the website on their computers if you make your local server. The local server is secluded to the device that is running it (although if their making their own local server and have your project files it should work just fine).
If you want the website hosted so that you could share a link with anybody in the world you could use codepen or github pages. If you go to codepen.io it should be self-explanatory although you'd have to upload your images to some image hosting site like tumblr or something and add the URL source of those images to codepen or you could put everything into github for even better results!
To use github pages you'd need to make a github account (preferably with your username being whatever you want your page to be named). Make a repository named insert_username_here.github.io. add your files to the repository (make sure to try to keep all sub directories and folder exactly as they are from your project folder). After a minute or two go to http://insert_username_here.github.io to admire your brand new hosted webpage!
I have created a webapp using JSP,Html and Javascript which currently runs on my localhost using apache webserver. I want to display the files and folders and of a directory in local computer. I also want to create a download link or view link of those so that when anyone click on it it will be viewed in new tab or become downloadable as it happens in any ftp server. I know similar type of question has
been asked but none of them worked for me.
To create the download link I used
Download
this does not work as it is not in my webapp path and download attribute also does not work in internet explorer.
I'm not sure why you are exposing your local drive contents on the web but here's an option:
On the page that should display the files, in java code, list all
folders and files then for each file/folder show a link to some page
(for example "navigateLocalDrive" that sends the path of the clicked
file/folder like this:
Download
Now in that jsp, check if the GET variable is a path for a file or a directory,
if its a file, just send it back in the response, if its a
directory, list all files/folders and do the same as in step 1
Please note:
How I encoded the file path in the href in order to work properly.
The Access permissions for the webserver should allow write/read to that path (I'm already doing it on my Tomcat server on local host with the default setup no change needed)
For your reference, here are some helpers for this task:
How to list contents of a server directory using JSP?
Downloading file from JSP/Java
I am not sure if this is possible. In general the access rights are limited to the src and webContent Folder (for your html coding mentioned above for sure) . This is also reasonable, because you do not want to access or change data on your Computer in general, because after local development you want to deploy your web application to a server.
To make a test copy some file to the webContent and you will be able to download it. Within your Java coding you can use some IO package like java.io.File to navigate over folders and files. However keep in mind, that you will get some exceptions like
java.io.FileNotFoundException: C:\WeatherExports\export.txt (Access is denied)
if you want to access files outside the server.
I am Writing some php files and testing them on local server (xampp)
My problem is that when i directly open a file in browser by double clicking on it. it shows me local drive path like file:///C:/xampp/htdocs/folder/file.php i want to change or redirect url of SELECTIVE FILES to http://localhost/folder/file.php
i think i need some javascript but unable to find how?
PS: i do not want all the files to change url, but SELECTIVE files.
PHP files are supposed to be served up by the server, as such if you want to see the interpreted result of your work you need to access the file as the server outputs the file.
localhost/folder/file.php
If you are double clicking the file name and a browser is opening up, then you should configure your file editor to open up so that you can work on the php file.
Just to cover the basics you need to go to the xampp control panel and click start where Apache is. Check if your firewall is blocking the Apache process from starting (I had this error when using Comodo firewall). Then if thats ok you should do what Cups said above.
If that does not work you should open up a terminal (in Linux/OSX) or Command Prompt (in Windows) and type:
ping localhost
If that give an error you need to look into your Hosts file.
I am trying to test some JavaScript on my local computer using the Chrome browser but Chrome will not load local resources. Is there an easy work around for this?
If you are trying to just test the functionality of your JavaScript file: create a blank HTML file, add a link to your JS file as you would normally load a JS file from HTML, and open the HTML file in Chrome. Go to the JavaScript console. You'll be able to interact with the functionality of your JS code as usual. You wouldn't need to set up a server for this. If still not clear, here's an example:
<html>
<head>
<script type = "text/javascript" src = "path/to/your/jsfile"></script>
</head>
</html>
You can use a light weight webserver to serve the file.
For example,
1. install Node
2. install the "http-server" (or similar) package
3. Run the http-server package ( "http-server -c-1") from the folder where the script file is located
4. Load the script from chrome console (run the following script on chrome console
var ele = document.createElement("script");
var scriptPath = "http://localhost:8080/{scriptfilename}.js" //verify the script path
ele.setAttribute("src",scriptPath);
document.head.appendChild(ele)
The script is now loaded the browser. You can test it from console.
To load local resources in Chrome when just using your local computer and not using a webserver you need to add the --allow-file-access-from-files flag.
You can have a shortcut to Chrome that allows files access and one that does not.
Create a shortcut for Chrome on the desktop, right click on shortcut, select properties. In the dialog box that opens find the target for the short cut and add the parameter after chrome.exe leaving a space
e.g. C:\PATH TO\chrome.exe --allow-file-access-from-files
This shortcut will allow access to files without affecting any other shortcut to Chrome you have.
When you open Chrome with this shortcut it should allow local resources to be loaded using HTML5 and the filesystem API.
For security reasons, modern browsers won't load resource from locally running HTML files (files using file:// protocol in the address bar).
The easiest way to get a modern browser to load and run JavaScript files in local HTML files is to run a local web server.
If you don't want to go through the trouble of setting up a Node or Apache web server just to test your JavaScript, then I'd suggest you install Visual Studio Code and the Live Server extension.
Visual Studio Code
Visual Studio code is a source code editor for pretty much any programming language under the sun. It has built-in support for JavaScript, HTML, CSS, TypeScript, and almost any kind of language used for Web development.
Install Visual Studio Code
You can get the Visual Studio Code editor for your platform from https://code.visualstudio.com/. It supports Windows, Linux, and Mac. I think it also works on your Surface Pro if that's your thing.
Add the Live Code Extension
After installing VS Code, you can add the Live Code code extension using the Extension panel (Ctrl+Shift+X in Windows) in Visual Studio Code.
Live Server Extension
After adding the extension, you should see a "Go Live" button in the bottom-right corner of the Visual Studio Code IDE (as shown in the above screenshot).
Open in Code
Open the root folder where your HTML and JavaScript files exist in Visual Studio Code and click the "Go Live" button. Optionally, you can right-click the HTML file in the Explorer (Ctrl+Shift+E) and select Open with Live Server from the pop-up menu that appears.
Open with Live Server
This should create a locally running web server and open the file or folder in your web browser. If your file paths are correct, your JavaScript files should also load and run correctly.
Troubleshooting
If for some reason, the page doesn't load in your favorite browser, check that the address and port number are correct. If the Live Server is running, it should display the port number in the bottom-right corner of the Visual Studio IDE. Make sure the address in your browser says http://127.0.0.1:<PORT>/index.html where <PORT> has the same number as shown in the status bar in Visual Studio Code.
Use Chrome browser and with the Web Server for Chrome extension, set a default folder and put your linked html/js files in there, browse to 127.0.0.1:8887 (0r whatever the port is set at) in Chrome and open the developers panel & console. You can then interact with your html/js scripts in the console.
The easiest workaround I have found is to use Firefox. Not only does it work with no extra steps (drag and drop - no muss no fuss), but blackboxing works better than Chrome.
You can do it by a feature of chrome's DevTools: Snippets
Create a new snippets
Copy and paste the file you would like to execute.
Hit CtrlEnter to run the snippet
Windows 8.1 add:
--allow-file-access-from-files
to the end of the target text box after the quotes.
EX: "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --allow-file-access-from-files
Works like a charm
Running a simple local HTTP server
To test such examples, one needs a local webserver. One of the easiest ways to do this is offered by Python's SimpleHTTPServer (or http.server, depending on the version of Python installed.)
# 1. Install Python 3 & use:
python3 -m http.server
# On windows, instead of "python3" try "python" or "py -3"
# If you installed python version 2 then use:
python -m SimpleHTTPServer
# 2. To serve a specific folder use the --directory flag:
python3 -m http.server --directory /Users/junaid/WebstormProjects
# Note: I use MacOs & I have given the absolute path to my projects folder & I was able to serve my desired folder.
Here's what I did by creating 2 files in the /sandbox directory:
First file: sandbox.js
Second file: index.html
const name = 'Karl'
console.log('This is the name: ' + name)
<html>
<head>
<script type = "text/javascript" src = "file:///Users/karl/Downloads/sandbox/sandbox.js"></script>
</head>
</html>
You can then use Chrome or any browser to inspect and debug/console your code!
setup
You will want to serve the file from a web server. Everything else will be quirky workarounds that might differ greatly from the final result. On the web, files are being served via web servers. You'll want to mimic that locally.
Since you're apparently (at least part-time) being a web developer, do yourself a massive favour and install node, if you haven't already. It comes bundled with the npx binary, which we'll use. Make sure you have a recent LTS version. Bonus points for using n, which will make it easy to stay up to date with your versions, and even switch them as you need.
steps to take
Inside the folder where your file is located: npx http-server -c-1
You can now access the file at http://127.0.0.1:8000/filename
Last thing to do is make the browser load the file. Magesh's answer works well for that, but I would recommend putting that snippet into a "custom js" extension. This one has served me well so far.
With everything in place, simply reload the page to get an updated version
of your local file.
Note: this question comes top on google when you search for "chrome read local css without server". So...
If you really want to serve a local webpage and load its CSS and JS, and you really do not have or don't want to use a http server, then don't load the scripts nor styles; inline them.
Instead of something like this:
<link rel="stylesheet" href="somefile.css">
Define the style like:
<style>/*Here goes all the CSS file content*/</style>
And the same with the JavaScript files. The HTML file will be larger, but it will work.
Basically you just have to copy the file contents and paste it inline.
You really should use a server, but if you are forced to, you can use this method.
If you still need to do this, I ran across the same problem.
Somehow, EDGE renders all the scripts even if they are not via HTTP, HTTPS etc...
Open the html/js file directly from the filesystem with Edge, and it will work.
for my use case, i need to startup a local server, create working an interactive html page, and open it for the user to be able to interact with it. the problem was how to set the local server's web root to my temp working folder where i create these dynamic files. this was a quick and dirty solution.
In the below code, LOCAL_WEB_DIRECTORY is essentially the root. and i then create/copy the files i want to open in the brower to that directory + /templates
import webbrowser
from http.server import ThreadingHTTPServer, SimpleHTTPRequestHandler
httpd = ThreadingHTTPServer(('', 8001), lambda *_: SimpleHTTPRequestHandler(*_, directory=config.LOCAL_WEB_DIR))
server_thread = threading.Thread(target=httpd.serve_forever, daemon=True)
server_thread.start()
webbrowser.open('http://localhost:8001//templates/' + work_html)
while True: sleep(1)
Not sure why #user3133050 is voted down, that's all you need to do...
Here's the structure you need, based on your script tag's src, assuming you are trying to load moment.js into index.html:
/js/moment.js
/some-other-directory/index.html
The ../ looks "up" at the "some-other-directory" folder level, finds the js folder next to it, and loads the moment.js inside.
It sounds like your index.html is at root level, or nested even deeper.
If you're still struggling, create a test.js file in the same location as index.html, and add a <script src="test.js"></script> and see if that loads. If that fails, check your syntax. Tested in Chrome 46.
The easiest way I found was to copy your file contents into you browser console and hit enter. The disadvantage of this approach is that you can only debug with console.log statements.
Look at where your html file is, the path you provided is relative not absolute. Are you sure it's placed correctly. According to the path you gave in the example above: "src="../js/moment.js" " the JS file is one level higher in hierarchy.
So it should be placed as following:
Parent folder
sub-folder
html file
js (this is a folder)
moment.js
The double dots means the parent folder from current directory, in your case, the current directory is the location of html file.
But to make your life easier using a server will safe you troubles of doing this manually since the server directory is same all time so it's much easier.
How to open an .exe application which is hosted on different server using html ?
var w = new ActiveXObject("WScript.Shell");
w.Exec("C:\Program Files\Adobe\Photoshp.exe");
I tried the above code but it's working with local .exe bt nothing is working with external .exe
Assuming this is an intranet stuff, try this:
w.Exec("\\\\Your_server_name\\C:\\Program Files\\Adobe\\Photoshop.exe");
or:
w.Run("\\\\Your_server_name\\C:\\Program Files\\Adobe\\Photoshop.exe");
Your_server_name can also be an IP address. Notice also doubled backslashes, and the fact, that the path must be absolute, you can't use any drive letters mapped in local workstation. Notice also, that usually server name is not the root of the server (like C:), rather it's pointing to a folder in the server.
Both examples work great for me, no matter, if the HTA is saved in the server or workstation. Only I could imagine why they wouldn't work (additional to a wrong path), is a case, when you have not rights to the referred folder. Or... you're trying to run exe from an external WEB server, which afaik is not possible.
I dont think you can do that using JS on client side directly as this will be a security issue. The best way to do this will be first download the exe file, via http and then run it. Once you try to do this user will also be prompted for it.
