well, I have a comment system that is updated every second with jQuery, but I want to update only if there are changes, that is, only if there are new records in the database. is there a way to do this?
Excuse my English, but I'm using google translator
You may create two function in JS. First function ask php script, which check changes, and, if data changed, run second JS function, which get data and update DOM.
Php is not may send info on loaded http page independently, without request from client side.

Posting data to the server needs a form-tag.
But do I also need a button of type 'submit' when I use ajax/jquery?
Can I not just interrupt the button click and do my own ajax request?
No, and technically you don't even need a form tag if you want to serialize the POST data yourself.
If you are using Ajax then you don't technically, need a form tag or a submit button.
Having them gives you convenient, semantic elements with logical events to bind the JavaScript to.
Having them is needed for the JS to be unobtrusive (which is a best practise).

You can use javascript's setInterval method to periodically send something to your server
For example:
setInterval(function(){
sendToServer()
},1000);

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.

So i'm using phonegap build with, html5 jqm and javascript and css obviously.
i have a local rss feed in xml format that has been made and will be updated with new events etc.
i want the RSS feed to show like a list basically at the moment i'm no bothered with anything fancy look as i've not even managed to get it to show up, all my efforts have been futile.
Any answers accepted. For practicality lets call the feed rss.xml.
Thanks!
You may use jfeed, for example
jQuery.getFeed({
url: 'rss.xml',
success: function(feed) {
console,log(feed.title);
}
});
Also, you can use $.get, here is an example for PhoneGap and an article worth reading.

This is most likely a very simple question but i am new to server-client programming i am used to only a client. I want an action that is taken on one person's browser to effect the state of the screen to all people that are looking at it.
I doubt it is that hard but i have no idea. And after some googling i can't find anything.
Take a look at websockets, which allow you to open up a constant connection between the client and the server.
Basically you will need the "host" to send its screen data to the server via websocket (or possibly AJAX), which can then transfer the data to the "viewers" (which is where the websockets will be superior to AJAX).
