I Need a javascript to check if a firefox extension (not plugin) is installed.
I've created a clickonce application and I need my users can open the clickonce app with firefox, I know there is an extension from Microsoft to to this, but I need to know if that extension is installed, if not, I want to send to my users to the correct url to get the extension.
Thanks.
The only real way to do this outside of creating your own extension that reads other extensions is if the extension you are looking for injects something into the global variable scope that you can detect the presence of.
if('someExtensionObject' in window){ ... }

I am working on a OSCommerce site, and i can't figure out why is this happening.
You can check the website at the url: http://tendance24.com
The layout is completly different on IE and i'm wondering why cause all the should work for IE.
I am wondering if it couldn t be javascript.
Please let me know if you want me to upload all the css file somewhere, or anything else.
Thank you
It's because you're seeing it using Internet Explorer's Quirks Mode.
The website will only render correctly using Internet Explorer in Standards Mode.
If you press F12 when the Browser is in view and you'll be able to change this from Quirks to Standards mode.
This post will help solve the issue.

There is an option for disabling right click on the website on the computer but on the mobile I don't know which javascript code I would need.
Images have to be copied from the web server to the client system in order for the client system to display them.
There is no way to stop people from saving them.
There is an option for disabling right click on the website
Not one that can't be trivially bypassed.
There's no way to actually block an image from being copied. If it's being shown to the user, they can obtain it. The resource is already sent to them for render anyways.

Because of browser related issues (ie, the view being different), I have two versions of a script. one that works on everything but IE, and one I wrote specifically to accomodate IE.I found this other script that detects what browser someone is using when they access a website. I was wondering, if there was anyway i could:
1.run this browser detect script FIRST to determine the boolean for IE/not IE
2. then, determining on this value, run one script or the other?
So... What's stopping you from doing:
var IE = checkBrowserFunction;
if(IE) {
doStuff();
}
? I mean, that seems fairly simple.

want these things when a function call :
1.Open a text file (not visible to user)
2.Select a Text which is to be change
3.change the text
4.And save it at same place.
This is not possible in JavaScript. JavaScript is sandboxed by the browser and doesn't have access to the local computer.
Also, what you're trying to do sounds dodgy, and may well be the exact reason why it's sandboxed.

I've downloaded Canviz (it's a Javascript library for drawing graphs). I've unzipped the archive. I open, with Chrome, index.html, which is supposed to be an example. A "loading" message appears... and never disappears.
What am I supposed to do please ?
I worked with this library a few months ago.
You also need to have graphviz installed in order to create the graphs canviz will draw.
When you have installed, you have to use the function load with the url parameters in order to create the graph.
WebBrowsers have an option to enable javascript or not. make sure your browser enable it.
here's an example for Mozilla : Mozilla example
