Is it possible for me to write html/css/javascript to have a button that'll open up the terminal program on my computer and run some scripts?
The scenario I want is:
On my ubuntu laptop, run my node-webkit app, click a button on the screen, a terminal opens, and start executing some scripts.
Thanks
from web page you cant do this but you can use node.js , if you want to make a GUI app with JavaScript you can use node-webkit with it you can build cross platform software that can work with Linux and execute commands in the terminal
You can do this from a webpage, but make sure your hosts.allow (or equivalent) is set to localhost only. Just run any web server with cgi capability and drop in your cgi script that runs your scripts into the cgi-bin directory. Then just add an empty form submit button or link to localhost:8080/cgi-bin/your_script
Slitaz uses this for their entire configuration system using busybox httpd and shell scripts, but uses shell generated interactive forms instead of a terminal. See: http://hg.slitaz.org/tazpanel/file/
Another way to do it without a web server (at least with firefox/seamonkey - not tried with chrom) is to associate a file extension so that files with that extension are opened with that script. Then just make a link to an empty file with that extension.
Use child_process module:
<script>
var cp = require('child_process');
function run() {
cp.exec('gnome-terminal -x bash -c "./your_script.sh; read -n1"');
}
</script>
<button onclick="run()">your_script.sh</button>
You can also remove read -n1 and simply run
cp.exec('gnome-terminal -x ./your_script.sh');
in case you don't want to wait for any key press.

The title says everything..
I would like to execute special shell commands when a specific button is pressed in HTML or Javascript. If possible, can you also give me a test code??
I was wondering if I could make them auto-start in an arch live USB / CD installer and make those HTML pages as some shell command-executor.
You can execute linux commands only at backend (php, nodejs, etc).
I have implemented a nodejs server that serves incoming requests to use the bluetooth services of the local computer. I want the nodejs server to be packed as an windows executable file so that I can distribute it. People should be able to just install/run that .exe which will install any packages required (if any) and run the server. How to do this?. I saw and tried node-webkit etc., but they are UI-centric, that is it can pack a nodejs application that opens a html page. But I want my server javascript file to be executed, like the way it is done in command prompt : node file-name.js. How to do this?
I've a server running with nodejs and for execute this I use a .bat file.
Create a .bat file
Inside of the file put:
cd path/to/server/
node índex.js
I used JXCore for this task in the past. It basically creates one executable that includes everything.
Unfortunately active development of is halted.
Solution:
You can use nexe for that.
Create a single executable out of your node.js app
Motivation
Ability to run multiple applications with different node.js runtimes.
Distributable binaries without needing node / npm.
Starts faster.
Lockdown specific application versions, and easily rollback.
Faster deployments.
I am trying to create a JavaScript pacman game, but whenever I try and load my script files or images, I get the error:
The browser I'm using is chrome, and the files are stored in the same directory. I am running CHROME OS, so I can't just go into files and edit an existing flag.
Same for the images, except the file name is different.
Does anyone know why I am getting an error Access Denied, or how I could test the files?
The files are loaded using this format
<script src="Scripts/gamescript.js"></script>
<body>
<div class="game" id="game">
<img src="/Images/ghosts/red.png" />
</div>
</body>
Per request, here is my file tree
/Javascript_Pacman_Game/
index.html
/Styles/
stylesheet.css
/Scripts/
gamescript.js
myCustomLibrary.js
setInterval.js
/Images/
/Ghosts/
red.png

The problem isn't spelling or file permissions, and I can't run a local host because of Chrome-OS.
Try installing Web server for Chrome, telling it to serve files from your /Javascript_Pacman_Game folder, and testing your app at http://127.0.0.1:8887/
If you have to handle this from chromium OS (specially with dual boot cloud ready), follow the steps
Step 1:
Go to the shell prompt Ctrl + Alt + T on shell open the chrome_dev.conf
$ sudo vi /etc/chrome_dev.conf
The sudo default password would be 'chrome', The file may be write protected follow these steps incase if you stuck in step 1
$ sudo cp /etc/chrome_dev.conf /usr/local
$ sudo mount --bind /usr/local/chrome_dev.conf /etc/chrome_dev.conf
$ sudo vi /etc/chrome_dev.conf
Step 2:
Once you open up the file write --allow-file-access-from-files on top of the file
Step 3:
Restart the UI (if you are using windows dual boot press CTRL + ALT + F2) from dev shell
$ sudo restart ui
Once its restart the changes will get affect in chromium OS chrome, to check type chrome://gpu on your chrome browser
Under command line Argument you can find argument options.
You really should be running a local server. Apache, IIS, etc. Than you can run off localhost and have no issues.
BUT if you really want to run off the file system, you need to start up chrome to allow it.
You need to set --allow-file-access-from-files

It sounds like your permissions have been edited (or defaulted) to restrict your current user from accessing those files.
I managed to reproduce this error by creating the same file structure you have and then
right clicking red.png > properties > security > edit...
then denying access to this file from my current user. It seems that if you deny access via the directory you get a File not found error instead since the browser isn't even able to navigate to the directory in the first place.
Try checking your individual file permissions. If this is a default file permissions issue you may want to ask about how to fix that on a different forum.
The error is from your spelling, the first one you said
gamescript.js
and you called it as
script src="Scripts/gamscript.js"></script>
Check your spelling, you did not include "e"
Use Chrome Dev Editor as your IDE, then you can just hit the run button in the top left.
You could also use this Server.
javascript doesn't have access to the filesystem of a computer for security reasons do
<script src="Scripts/gamescript.js"></script>
I was wondering if it is possible to run a browser (specifically a browser engine) on the server side. I do not just mean to render a page but to keep a browser open for some time, run some JS, do some clicks or press some keys and meanwhile grab the graphical output.
Does anyone know how to accomplish this? So far my only idea was to run the browser in a VNC, RDP etc. session but this seems like an overkill to me.
PhantomJS does what you are describing. It is basically a headless browser - http://phantomjs.org/
you can run it server side via any server side language. See some integration modules below for NodeJS and PHP
NodeJS

https://github.com/sgentle/phantomjs-node
PHP

Yes, it it very possible to run a web browser on a server. Ubuntu Server, for example can run firefox by simply installing firefox and xserver.
$ sudo apt-get install firefox
$ sudo apt-get install xserver-xorg
Then to get firefox running type:
$ X
This will leave you with a blank screen because there are no applications running on the display yet. You need to shift back to a new terminal with
Ctrl-Alt-F2. Ctrl-Alt-F1 holds the X process now.
Login to the new terminal and set the environment’s display variable to :0 and launch firefox.
$ export DISPLAY=:0
$ firefox &
Firefox should now be running, but you'll notice it's got some quirks to it. If you decide that you want to go forward with this you should install a window manager. I'd go with a lightweight tiling window manager and run firefox and whatever other applications need graphical output within that window manager.
I want to create a simple Javascript program with a HTML interface. The program will run in Chrome. I will also use node-serialport and Node.js to comunicate with an Arduino. I have a HTML and JavaScript file done, but I have no clue how to run it, or how to implement Node.js or node-serialport, nor how to "start" the sever. Initially it will only be running locally, but eventually it may become a real sever. For now, how do I run all that locally?
EDIT: I'm using the sample code from http://brandontilley.com/2012/03/02/controlling-an-arduino-from-nodejs.html, with the CoffeeScript converted into JavaScript.
Lucas, glad you found the blog post useful; perhaps I should add this information to it.
Getting the sketch into your Arduino
Just fire up the Arduino application, paste in the sketch code, and hit "Upload." Should be all you need to do here.
Starting the Node.js Server
What operating system are you using this on? Finding out how to access your Arduino microcontroller via node-serialport will differ based on your OS.
In the source code, change the string value of port to be your Arduino's device (once you know it). Also, the script depends on Express and (of course) node-serialport from NPM, so run npm install express serialport in the directory where your JavaScript file is saved. Finally, run the file with node server.js (assuming server.js is the name of your file). Then you can access the server at http://localhost:8080.
You can use node.js to serve up HTML with Express. If your main Javascript file is called server.js, then run it by typing:
node server.js
at the command line.
